[SOLVED] No USB connected. How to solve? - Galaxy S III Q&A, Help & Troubleshooting

My Galaxy S3 doesn't connect any longer to my PC using a USB cable.
Better said, when I connect it, it makes a sound but nothing else happens, no change in the notification panel, and under settings USB tethering is unselected. Needless to say, my PC does not see the device.
I exclude a cable problem as I have two cables (one original) that were both working. I also exclude a PC problem as the situation replicates on both desktop (Win 7 x64) and notebook (Win 7 32-bit),and the latter has not been updated or had new software installed.
What I attempted:
un/select USB debug mode
un/install Kies
un/install Samsung USB drivers
wipe cache/dalvik/data reset+ format system + restore old backup from CWM
Does anybody have a suggestions on how to proceed? Thanks for your help!

Just on top on my head-do you maybe connect it to or thorugh a usb hub to a pc.
If so try directly into a usb on the pc.

Before I had been using with success a USB hub (only the desktop only, not the notebook), since I have been experiencing the problem I have also tried a USB port to no avail.
As I stated, I am pretty sure the problem lies with the phone, in fact since my original post I have seen a similar thread at here at xda

I tried everything and at the end brought the phone in for assistance.
Turns out the problem is hardware-related, on connector pin was burned. The connector has 4 pins out of which two are sufficient for charging (which is why it was being charged by the pc) but all 4 of them are necessary for the phone to be recognized as usb device.
According to the technician to whom I spoke, it happens occasionally but is not a systemic problem.

Problem using the SGS2 as an External USB drive !

As per the heading, I abandoned carrying a USB memory stick years ago, instead I have a 16GB memory card in my phone and carry a 15CM micro USB to USB cable in my pocket, this way I can use my phone as a USB drive when ever I need it, but I have a problem with my SGS 2
1) the drive seems to randomly disconnect itself whether or not it is transferring data
2) the option to ask me what I want to do every time I connect my USB cable is missing, forcing me to go to settings--> wireless and networks---> USB utilities, just to use my phone as a USB drive ....... VERY IRRITATING
does anybody else use this feature, if so what are your findings ?
I have a similar problem, it will disconnect randomly but also when trying to update and some times when trying to transfer files. I do however get the option to view files pop up when I plug it in. I made a post earlier but no one replied, hopefully it can be fixed easily. I wouldn't really know where to start though

Um, there must be something wrong with your phone. I have not done anything special to use my SGS2 as a USB drive. It's litterally plug it in and away you go.
I just plug it into the computer, the phone says something like MTB in progress, Kies connection or whatever.
Then I get the option to view all files and folders in My Computer (windows 7).
No problems whatsoever.

I don't normally use the "MTB in progress" version as the majority of computers I plug it into do not have kies loaded.
I use the standard USB drive option in settings
Bump
Anyone else having this issue

Hi,
i dont have any USB connection issues, loaded my 32Gb SD and the internal Storage full and i do use a lot the Mass Storage funktion, somtetimes the connection lasts for hours, so (Win7 32Bit).
Totally agree, the settings--> wireless and networks---> USB utilities ... tapping is verry annoying. Have to do this many times a day
Maybe someone knows an solution how to set the "Mass Storage" connection as an default?
Greetz Tokl
try multimount off the market.
You need to enable usb debugging (to prevent the keis rubish launching).
then anytime you want mass storage mode, click the multimount widget.
-- Actually just enabling USB debugging seems to set mass storage mode as default.
I have the same problem but I think it's the problem of the USB port on your PC. I plug the phone in another port and everything is ok now. You can try this on another PC or another port and you'll see. Hope this helps

1) Doesn't happen on mine. Have you tried using USB ports on other computers as it could be due to a particular USB port on a particular computer doesn't supply enough current?
2) It's irritating.

So you don't have a usb icon in the notification area? Otherwise, you just have to select it to enable usb storage.

Thanks Mate!
USB Debugging prevents Kies and bring up the Mass Storage directly
One more (very small, but annoying) issue of the SGS2 solved
Greetz Tokl
When I enable debugging mode, I does indeed turn on mass storage mode and it works. However, every time I unplug the phone it reboots. I do press the disconnect USB drive button and I do eject it on my PC. It still crashes. Does anyone else have this problem?

This happened to me today, and the reason was the Android browser application running in background. Using the task manager I killed browser and then I faced no problem thereafter.
So, to sum up I guess an application running in background might be the reason.
Hope this helps somebody...
It's funny you should say that, as I hardly ever get that problem anymore, and I mostly use dolphin hd browser now

If it is connecting in download mode then the cable is perfect. Flash the firmware again to check if it is working or not

This was an issue since i had gingerbread. I upgraded to ics, didmt solve. Jelly bean, nope! I flashed neat rom, still the same.

[Q] Usb problem.

Hi everyone.
I got this problem with my Galaxy: when connecting with usb cable to my pc, the phone isn't recognized at first try. Sometimes it starts the explorer on pc but I can see no files in the phone memory nor in sd memory. After unplugging and plugging back again 3 or 4 times it eventually works properly.
Can you help me?

Try to clean USB port in your phone or use different cable.

R: [Q] Usb problem.
Already tried it. I've also tried all the ports on pc..they all get the same problem. May it be because of the lock pattern?

Clean install of USB drivers .
jje
I'm having trouble connecting to my Windows 8 laptop. I have reinstalled USB drivers and whatnot, but usually my phone is not recognised at all. However, if I use SGS3 Easy UMS app from Play Store to toggle MTP off and on while connected to USB I get the PC to recognise my device after a short while. It's so strange.
Usually I just use Samba server to transfer stuff because getting a USB connection is so complicated. USB (MTP) works normally with my Windows 7 PC at my workplace, though.

I'm going to try Easy UMS.
I don't have the possibility to connect wirelessly bc I don't have any wifi router at the moment.

[Q] Can't connect to PC in anyway, shape or form!

Can anyone help?
I am a newbie to Android, but a bit of a pro with IOS!
My Brother in Law has been passed down a Galaxy S II by his Father, and want's it unlocking to all networks, so once again I have been dragged in to do it as with anything tech related.....
I have read the forums and understand how to root and unlock etc., but here is my problem.
I can't connect the phone to the PC in any way, shape or form.
It is locked to T-Mobile and is model GT-I9100 on 2.3.3 Gingerbread.
It won’t connect to Kies, Odin, or show up in explorer as a USB device etc. I have tried the suggested methods of debugging mode etc., tried various cables, different PC's, drivers.
I believe the fault is the phone, as if I plug my friends S II in Kies see it right away and installs drivers no problem, however they and on version 4.x.x.
The phone will charge via PC USB and also when I connect the cable it brings a screen up showing a USB plug and says MTP Application at the top and says connected, press the home key to quit Kies. But other than that nothing.
I also tried to update the software from 2.3.3 to the latest software via Wi-Fi from the phone, but again it gets as far as connecting to server for about a minute then just says connection failed.
I can only think it either has a software corruption or a faulty dock connector? Or perhaps I need drivers compatible with Gingerbread 2.3.3 and Windows 7.
Any help please!
I'd be replacing the USB board/port; quick/easy/cheap (~US$15) to do - search for KeithRoss39's guide in the General sections, has all the info you need.
Thanks for the reply.
Just had the back off and gave it a good clean, but no joy, so that may be the next step.
However when I connect the USB cable from the PC to the phone, the phone does pop up the MTP USB Application image on the screen.
But it isn't detected by PC at all.
Any ideas?
Yes. Replace the USB board/port. It often will show only a few faults (like you're seeing) rather than crap out completely. This is what I would do if I was in your situation.
As @MistahBungle says.....these ports do fail......
There are a number of specific connectors within the port.....each one controls a different function. So it IS possible for the port to remain functioning for charging while failing for PC connection (for example).
There really is no other option than to replace the whole port/board assembly.........

Question Problem with file transfer on windows

Does anyone have issues with transferring files to a windows PC? I plug my phone in and under USB preferences its grayed out. I've tried the xperia companion and it seems like my device isn't recognized because the option to browse my files is grayed out too.
It happened to me because I was using the usb-c cable that comes with the same phone.
What I did was look for another usb-c cable that I had at home (from my Xperia 5) and when plugging it into Windows 10/11 it recognizes it perfectly and on the phone you put "Allow" and you can transfer files.
Apparently the cable that comes by default in the box with the Xperia 1 Mark III does not support data. Greetings

The cable that came with my Phone (Phone bought from sony partner from official site) wrk for file transfer without problem (under win 10 e win 11).
Maybe different market, different cable bundled in?
Yeah, I also bought it from the official Sony store via Amazon. When I plugged it in and saw that it didn't work for data (or for recovery via Xperia Companion) I started googling and investigating and the same thing happened to several users. Mine is the UK Bundle version.
It seems a normal problem on different phones. Usually, it will be solved when we change an offical USB cable. Or if your computer and your phone are in the same network, you can also try WiFi connecting. A third-party tool like Coolmuster Android Assistant allows us to do that. With its help, we can do that data transfer via WiFi connecting directly.
use adb push/pull commands much better.
I have the same problem in Linux, enabling USB debugging in developer options sometimes solves it. Very flakey however, its 10 years since I had as much trouble connecting a phone to a PC

Question Couldn't connect my device to computer.

I am using usb cable to connect my phone to laptop but the phone doesn't show any transfer notifications. My device only charges.
I tried uninstalling usb drivers and reinstalling them on laptop which didn't work.
I used the same cable on other laptop and it worked fine.
Is this the fault of my laptop or my device? Can someone provide solution to it?
If it works on a different laptop it sounds like your laptop is the issue. What make and model is it, and running what OS?
