is there any one know?
I have huawei E170 3G modem and disable flashdrive mod. I disabled with DC-Unlocker client
But Tablet S did not recognize the 3g modem (Unsupported USB Device Connect)
Please Developer Friends Help me.
Thank You

Here you've got some info. Unfortunately you will have to wait for a root solution.
yes I tried some posts but nothing else
Yes we are waiting developers friends
Tried it using an aircard but android only picks up the usb stick.
I dont know if it actually help but I saw this on tech republic when they open the tablet.
3G-ready motherboard and case: Sony left an open spot on the motherboard and inside the case for a 3G or 4G card. The internal mounting bracket even has screw holes for it.
Dont know if it is possible to add an internal modem or install driver for that.

At least worked for me. It disables other functions of USB 3G sticks and leave them to be acting only as 3G modem, which then tablet recognizes.
Is there anything new? I have got rooted ICS on my tablet. Is it possible to use 3G USB Modem on my tablet? I have got 2 USB-Modems. The first is ZTE K3565-Z and the second is Option 4G Systems XS Stick P14. Is there a solution?

If darkjesus's method didn't work, then I'm not sure anything will. These modems are not easy to work on a lighter system like Android.
I'm happy to be proven wrong, of course.
In a german forum, i found an app called "UMTS Manager". With this app you can connect with 3G Networks with some Huawei-Sticks and maybe some other devices, too. They use mode-switch to switch device mode to modem only and then it works for them. Here's the link:
http://www.android-hilfe.de/asus-ee...-stick-zum-laufen-kriegen-17.html#post3236187
Of course, a lot of pages But some of them got ZTE K3565-Z working. For me it doensn't. Maybe we can find a solution
I found the reason, why it does not work on Tablet S. Our Tablet does not create ttyUSB*-devices when attaching 3G Modem to the Tablet. Normally it creates ttyUSB*-devices, attaches the Modem there and you are able to connect. I think it's a kernel issue or Sony modified the kernel. But with Custom Rom and Kernel which has got this "feature" it is possible to connect via 3G Modem. Maybe one of us could create this custom Rom..
So how?
Hi there friends
So any tablet s user here found a way to use 3G on this tablet?
About a year...is this question solved? I just bought sony tablet s 32gb wifi and of course hoping usb modem work

You will have better success looking for a portable 3G-to-WiFi hotspot device. Not only will you not have to worry about installing USB modem drivers, the device will work with a non-rooted tablet. Also, if you have a 3G smart phone, look into WiFi tethering.

Yup, finally I bought portable 3g/4g wireless n router. Easy to use. Thanks by the way.
Wondering if anyone here has been able to use a 3g dongle using otg cable and y-cable? Does ICS have any drivers built in?
Thanks
Bump anyone?
What is an otg cable and y cable?
Otg. Cable is basically micro USB to USB cable and y cable is required in order to provide power to the device you'really using.
I'm pretty good at figuring out bad lingo but I'm not quite sure what you're trying to accomplish. Are you trying to get 3g on your touch pad or power the 3g dongle like a hotspot? I'm assuming the micro USB to USB plugs into the touchpad and part of the USB "Y" cable and the dongle into another part of the "Y" but what does the y cable plug into? Being detailed and descriptive goes a long way to getting answers on the interwebs.

Figured the people that would know if it works/how to get it to work would already know what the cables are seeing as its the same equipment required to hookup any USB device, be it a keyboard, USB flash drive or external hdd to the touchpad.
Basically I want to use the 3g dongle to get internet on the TP. To do this would require external power to the dongle as the TP doesn't have a powered USB host. Most likely require drivers as well.
wouldnt tethering to a cell phone that already has a nice data plan be much better than a franken-dongle setup?

At least in the US, tablet device plans tend to be cheaper than tethering plans and carriers are starting to crack down on such practices. Its a valid request.
Not really sure if its possible on the touchpad, but I know some other devices are capable of it like the Archos G9 series and some Chinese tablets so I would not be surprised if it were.

I think most US carriers would be unhappy if you used a 3G USB Modem with a tablet plan since the modem could be used with a laptop too. Pretty sure it would be against ToS to do so.
In any case, if that's the route someone wants to go, then wouldn't some sort of 3G Wifi hotspot still be better than a "franken-dongle"?

Good point on both accounts. A mifi type device would probably be the way to go, less cables, more universal usage, etc. Only downsides being that its pricier than a 3G dongle and the battery life would not be as good, but it would be guaranteed to work.

Yeah, i tether via wifi to my android phone all the time, i also use it as an external gps receiver for my touchpad. It just seems much easier, i'm already paying for the data plan why the hell should i pay some ripoff carrier another 30 bucks a month for data on my tablet. This would however be nice to see if an external dongle will work.
all valid points. I currently tether to my phone as required, however work has issued me with a 3g/4g(LTE) usb dongle that i would like to be able to use (in addition to all the other 3g dongles i have lying around).
I've seen the wifi adapters on ebay that you can just plug the usb dongles into, but to avoid shelling out extra $$ i thought i'd see if there was any in-built or easily implemented support for usb dongles.
Having seen the cheap chinese/ebay tablets running GB with usb dongle support i figured surely there must be drivers out there that could be adapted to work with ICS.

Looks like someone did it with a wired dongle for the Touchpad...
http://forum.xda-developers.com/showthread.php?t=1552102
So maybe someone could do the same for a 3G dongle?
And it also looks like there's a way to a 3G dongle working with an Asus Transformer on Honeycomb...
http://forum.xda-developers.com/showthread.php?t=1151097
although it takes quite a few steps and doesn't work on ICS yet.
I also found this...
http://it-depot.net/pages/3G_Setup
But the guide doesn't mention what tablet or version of ICS this should work on. On my Touchpad running CM9 nightlies I don't have a Mobile Networks options. Between the vagueness of the guide and CM9 being an alpha, it's kinda hard to figure out what the issue might be.
I guess your original question was, has someone made this possible for a Touchpad already? And it seems to me that the answer is no, but it eventually might be done. It looks like you're not alone in wanting to get a 3G USB modem to work on an android tablet, if that gives any hope.
Thanks gmkelly.
I'd seen those links before and tried to find that mobile networks option. From what i can tell, it looks like ICS might actually have some drivers built it, but whether they are in CM9 is a different question.
I also kept a close eye on the wired lan adapter thread posted yesterday (?). If a wired adapter can be implemented, maybe it wouldnt be too much effort on getting the wireless 3g implemented...
Forget US carrier restrictions. This feature would be an absolute godsend in a country like Nigeria where a 3G dongle is pretty much the best way to get online in most places.
The only issue I see with this is that a lot of 3G dongles are only Windows / Mac compliant. Meaning that they hate linux or anything that isn't Winbl0wz XP (or 7) or Mac OS X 10.5+. And Android definitely doesn't fall under that category. Just like consoles (which I have seen people try and use the dongles for, too).
However, if you CAN get them to work, you'll be a hero in the tablet community.
3g dongle works with hp touchpad now. Check Josh's PPPWidget forum. I am using a ZTE MF110 with it on CM9 and get better performance than on a win7 machine.
Hi fellow owners,
I am considering to buy, but I'd prefer to be a cheap and get the 16GB WiFi version. However, it would be nice to be able to use a USB dongle for 3G from time to time. Anybody tried?
Thanks!

good advice. I can certainly do this as well as use a 3g wifi router i have. but using the phone's hot spot drains phone's battery and using a router adds to the bulk. that is why I'd like to try a dongle.

I read in the GSMArena review that the XTZ can be tethered to a phone using Bluetooth:
Even if you get a Tablet Z without 3G, you can still use mobile Internet, provided you have a data plan on your droid phone and the Xperia Link installed. The app simplifies the tethering process. It puts a widget on the homescreen that lets you turn tethering on and off.
You might be thinking that you can just use your droid's Wi-Fi hotspot feature to do the same (and you could). The difference here is that Xperia Link uses Bluetooth to share the Internet connection and not Wi-Fi. This should be more power efficient than a Wi-Fi hotspot especially considering you can keep Bluetooth on all the time, which will let tablet and phone hook up automatically once they are close enough (you can't do that with a hotspot as your battery will be dead in a couple of hours).

I haven't been able to try that yet -- my pre-ordered XTZ has yet to ship -- with my Nexus 4 but it could be a solution to Wifi Hotspot battery drain issue.
-- Edit to add --
Well, found the official Sony Xperia Link in the Google Play Store and it's incompatible with non-Xperia phones apparently. Although, the Bluetooth-tether idea still sounds promising. Is there a way to get around the Sony lock-in?
Works!
So I've got the tablet this week and tried just now to stick the USB modem into it.
Naturally you have to be rooted, then you need a dialer :
PPP Widget
from the author of usb_modeswitch (ubiquitous linux tool to change the usb modems from CD to serial mode)
then you need the usb drivers unsurprisingly missing from the stock rom:
On author's forum
then insmod the modules in the zip file:
cdc-acm.ko
usb_wwan.ko
option.ko
(option requires usb_wwan to be loaded first), drop the widget on the home, it should do its magic and ask you for the APN. Then it works.
what a joy.
p.s. apparently the dongle I have needs more power than there is on the tablet port, so you need a powered hub (clumsy) or an external battery and a Y cable to power it.
Supported list (GA models. Says 4.2, but same for 4.4.4 iirc)
http://i.sbo2.com/page/GA Series Android 4.2 Manual_EN.html
You may need to change/add apn settings. Install this app to get to the settings: https://play.google.com/store/apps/details?id=diewland.settings.mobilenetworks&hl=en
I use this one: http://www.eonon.com/Others/Others/V0049.html (is cheaper on ebay)
Also make sure that the cable is connected firmly to the back of the headunit
Useful information:

Could someone direct me to where the support list is found? The top link doesn't work. Just wondering if there has been any additions.
I'd like to have 4g ideally, is this even possible with these units (I own a huifei)? Can pick up a huawei e3372 for £15 on eBay

You can get other USB broadband modems working if you use the PPP Widget 2 app (https://play.google.com/store/apps/details?id=de.draisberghof.pppwidget2&hl=en). I found it to be pretty annoying though so I came up with an alternative solution.
I now use a TMobile Z915 mobile hotspot. I plan to install a switch to the battery so I can still use it when travelling, but I can otherwise leave it installed in the car and have it powered by the radio. When the car is turned off, it should kill the power to the hotspot. When power is restored it will power up and have instant wifi.
I'm tempted to try my 4G USB broadband modem again just to see if it works now that I've installed the Malaysk ROM. With my portable hotspot, everything is great except that the radio thinks it is always on wifi so it doesn't mind wasting data.
Hello,
I use the Huawei E1750 USB 3G dongle. I see it run not stable and do not know the reason. I usually used this dongle in PC before take it to my car.
Sometime, the HU did not recognizes the dongle, most of times, the problem happens when I start the engine from the HU running by battery's power.
I guess the power supply for the USB port is not enough.
My HU is Klyde MCTB-KLD. RK3066, 800 X 480, Malaysk newest 4.4.4 ROM
Is there someone met this issue before? Please kindly share your experience to help me solve this.
Thanks!

Hi guys,
I am also using a HUAWEI E1750 in my Carjoying HU and had the same problems but maybe I found a solution.
At least the behavior of the dongle improved dramatically.
1. At first I updated the firmware to version 11.126.13.00.00.B418
2. I think this is the important point .... I disabled the CD-ROM and SD-CARD function on the dongle.
You can use for that the DC-Unlocker.
In the white window on the bottom I used this command
AT ^ SETPORT = "A1, A2; 1,2,3,7"

I have a Huawei E160 and unfortunately the AT ^ SETPORT command doesn't work on my dongle. In the past I've tried AT^U2DIAG=0 which stopped it from working with my HU - fixed by reset using AT^U2DIAG=276.
Based on the above advice, I'm now trying AT^U2DIAG=3. It works with the HU but time will tell if it has fixed the reliability issues. I'll update this when I know more.

I tried and successed!
The AT-comand must follow this instruction from http://www.3g-modem-wiki.com/page/Huawei+AT-commands
The code for the "AT^U2DIAG=n" command depends on the model of dongle (Support by/Not support by)
The modem did fix quickly and more stable. But bases on the new firmware update feature: "More saving power" with your suggestion: "Disable CD and SD card reader", I think the main reason is the weak power of USB port. So, increase the USB power is more necessary because we may use any other device on it, not 3G modem only.
Thank you!
It hasn't completely fixed mine, the connection still drops out, but it MIGHT be better than before. Can't be sure though. Based on the above advice about firmware reducing power usage, I'll try that next.
This is for the benefit of anyone who owns a Huawei E160:
Do not install the latest firmware 11.609.10.02.432.b418.
After doing this, it wouldn't work with my HU at all. Unable to add APNs - they're not saved as the dongle is not recognised by the HU. It worked on my PC so wasn't broken, but the HU just didn't like it.
I downgraded to 11.609.06.02.94.B409 (was originally on 11.608.02.02.55 so is still an upgrade) and it now works once more.
I'm going to try out the different AT^U2DIAG commands to see if I can improve reliability.

Hey people,
I have a question. I have a 3g Stick Huawei E1750. It works very good, but I need 4G, because here at the most time only EDGE, and 4G is not supported by the stick. Does anyone knows a compatible working 4g STICK, not a Modem. Thanks

Hi there,
At 4pda, they are writing, that some PX5 units have troubles with WiFi/USB below 0°C.
It looks like my Witson unit (MX2 MCU, PX5, Android 8) suffers from exactly this problem. The last days we had warm temperature and USB and WiFi worked perfectly.
Now I went outside and the issues are back. It's 0°C now here!
Can anyone confirm this issue?
At 4PDA, they suggest a fix by adding a screw-whole + screw to better fix the proccessor unit:
https://4pda.ru/forum/index.php?s=&showtopic=883219&view=findpost&p=77467642
It looks like the processor unit is only fixed by 2 and not 3 screws and especially the two most outside pins, which are responsible for wifi and usb suffer from loosing contact with cold temperature.
I'm keen on trying to hardware fix. But I'd like to know if someone has experience with this?
Christian
Seems like a easy issue to check for and then apply if your unit has this issue. You might help others by testing the solution and posting result/images.

I now read the whole post in an ugly into german translated version.
The theory with the processor unit is not confirmed, the people over there discuss about powering issues for the usb ports, temperature-related problems etc. No finally confirmed fix seems availbale yet.
As my unit is less than two weeks old, I am claiming warranty. At least I purchased trough an UK dealer with paypal, so first I hope for a replacement.
If I don't make progress with that, I'll open the unit and look for the issue.
If someone elso would have a confirmed working fix, I'd try it.

There's another thread where a few of us have been researching this problem. The fix is posted HERE. There's no need to open the unit.
There's links in that thread to the 4pda forums where they explain what the issue is also. Long story short, it ends up being a manufacturing defect relating to the USB host controller. Newer versions of the board don't have this problem. But I can confirm the above fix does work like a charm, I've tested it several times.

Hi there, will comment in the thread you linked. I have running that fix with tasker already but still have partial drops of the host controller. I'm also working on a tasker task to switch WiFi on as soon as it gets off.

If anyone is still interested in a hardware fix, my KSP units have a 5-pin IC for USB current limiting and I found if the part is cooled, the USB will not turn on when it wakes up. I replaced one with a TPS2001DDBVT, same package and pinout but better specs. It passed the bench test. I haven't gotten around to installing the HU yet.
Update: I installed the unit with replaced ic, and it behaved differently, though not yet correctly.
It's worth noting, a Dasaita HU which has not exhibited the low-temperature wifi issue has the same USB hub chip, but a different (much larger) crystal attached.
I installed the newer usb hub chip as mentioned in the other thread. No more low temperature problems, however if I reboot the unit via software (with a rooted app), the wifi does not come on. One must reboot with the reset hole. Do not try this while driving.

Update: I installed the unit with replaced ic, and it behaved differently, though not yet correctly.
It's worth noting, a Dasaita HU which has not exhibited the low-temperature wifi issue has the same USB hub chip, but a different (much larger) crystal attached.

Hello
Can you make a photo of crystal and send it here?
Dasaita change something in board design (usb hub for sure) and currently doesn't exhibit cold temp bug.
Info confirmed with my friend with new unit.
I have older unit (from September) with older usb hub and need to make an upgrade.

Thanks for the info and question, I will send a picture, I can also compare to an earlier model, that's much easier than trying to trace the current circuit.

Hi
I have the same problem on my Dasaita bought on september 2018!
which upgrade do you suggest? hardware or software?
the problem occurs only with the dab module connected to the cable with 2 usb, while the single USB cable, which I connected the 4G wi-fi router, always works.
If I will installed the hal9k ROM, could I fix the problem?
thanks

I'm going for HW repair. I've ordered GL852 sop28 from ALiexp (0,55+3,4USD shipping).
Dasaita knows about problem with GL850, but they proposed to replace chip by myself or to send them SOM board and wait till they resend it back. well, i'm definitelly not happy with their response.
I hope that replacing USB hub will solve at least one other problem - random unmounting usb drives and problems with copying files from usb to sd-card.

How could I know if I have GL850 or GL852?

You need to open-up your HU to check. Also there is a thread on xda regardig WiFi/BT issues;

https://forum.xda-developers.com/showpost.php?p=78204931&postcount=70
and I think that you can check a type of the hub with app USB HUB

Ok. I'm going to check the chip model.
I haven't problems with the Wi-Fi or BT.
when the temperature is low the DAB module connected to the double USB cable doesn't work, everything else are fine.
could I have your same problem?
I changed the gl850 ssop28 with the better version gl852g. Now I have no real problems anymore with my xrc unit. There is a software fix in hal9k 3.1.1 in the mod settings but it was only working when it was not to cold. I had in cold days allway to wait and reboot the system ...

Change the chip is simple?
Which are items do you suggest?
There is a tutorial?
Thanks so much

No, it's not really easy, but without no skills before I did it. I just watch some desoldering and soldering videos and tried a bit with an littel another broken board with a ssop8 socket on it. I desoldered a lot and soldered a lot on it and then I change the chip on my mainboard.

I used a soldering iron beacuse I din't had a hot air station.

Judging from the comments you've bought this right? https://www.aliexpress.com/item/10P...96-43df-b7c8-2d03f857b97b&transAbTest=ae803_5
I might give that a shot.

Yes, I did. It's my picture at the feedbacks.
For me was it a good shot.
