[Q] USB does not connect to PC / ODIN / KIES - unable to detect - Galaxy S II Q&A, Help & Troubleshooting

Hi. I want to fix my USB connection.
S2 I9100 charge via USB to PC work (however, Kies or Odin is unable to find and connect properly).
Action steps done:
1. Updated Windows 7 with Samsung drivers - still does not see it
2. *#7284# -- checked settings to see if USB is in PDA mode.. - YES
3. Unplug and replug USB.. still nothing pops up via PC and device.
4. USB utilities settings does not do anything when selected
Q:
1. Where can I go to fix it?
2. Is it a missing driver?
3. What is the hardware or software called (terminology so I can search)?
4. Is there other samsung codes I am able to use to fix it?
Thanks in advance.. It's driving me crazy ...

Sounds stupid but did you try a different cable? I've seen many (mostly cheaper) cables which sometimes work for charging but don't work for data connections and sometimes it's the other way around. Also it sometimes helps to try a different USB port.

I have the same problem of no communication with Kies on one of my devices.
I have the benefit of two I9100's, one will connect the other will not, so in my case the cable and drivers are confirmed as good. Is it a hardware issue?

I used the SAMSUNG cable and nothing....

I think you must change the USB connector from your phone! Its a known Problem of 9100! Its cheap and easy to change!

My device is able to charge via USB to PC, would it be hardware issue to be replace?
Is there another reference to show how to change it?
thanks for responding! appreciate any help!

I had the same! On pc my 9100 was only charging! I changed the USB connector and now it works! Here is a video in German! https://www.youtube.com/watch?v=fWeZv4DMZ0Y&feature=youtube_gdata_player

[Q] SGS2 can't get along with my computer, desperate!

My SGS2 keeps disconnecting and reconnecting the usb with my computer. This is hapenning for quite a long time now.
I keep hearing the windows connect/disconnect usb sound when my phone is plugged in, making it unable to recognize the device.
Today, it finally didn't had this problem for a while, so I took my chance to get back to stock ROM (because I need to send my phone to Samsung for camera problems). So I flashed stock ROM with ODIN, but I encoutered a problem: it didn't get further than the boot animation.
When I tried to reflash, ODIN didn't recognize my phone anymore, just like before. When I plug in my SGS2 to my computer while on download mode, it just keeps reconecting the USB, so the device can't be installed.
Tried a different computer. It kept being connected, but that comp sucks and it couldn't recognize my phone at all. My own computer also has problems recognizing the SGS2, but also has the problem that it can't stay connected.
Things to know:
- Other usb devices do stay connected, it's just for my sgs2
- I've tried different USB hubs etc., reinstalling Kies, uninstalling drivers.
- It does keep charging the phone, even when the computer makes the disconnect sound. That makes it even weirder!
Basically I'm seriously out of clues how to revive my phone
I don't want to send it to Samsung, scared of losing warranty.
You guys are my last hope!
to start the ball rolling, YOU SHOULDNT BE connecting sgs2 to a HUB, thats probably the fault, second, have you tried a different usb lead or a different computer with the same lead to either verify if its the phone or lead at fault??
No one on here can answer your question because it sounds like a hardware issue, wire or hub or charger port, but it is an elimination process and only you can do that.
If you try everything and still get no joy, restore your pc to an earlier point, uninstall the samsung drivers and re-install them etc etc.
I very much doubt its a software problem tho, looking at what you tried already, lots of people use hubs, if youre flashing roms and your connected to a hub then ya play a dangerous game and risk soft bricking your phone, most of the time odin wont recognise your phone through a hub, same if ya usb lead is too long, itll charge but no data. always connect it directly to the pc usb 2 port.

Ow, I think I used the wrong word. I meant to say port instead of hub.. Translation fail there. So that's not the problem, I've put the cable directly into the USB port.
I think you are right about the hardware problem. I'm just not sure where the problem is. I only have one cable, so I can't test that atm. But like I said, the connection problem does NOT occur on another computer. It keeps the device connected (as an unknown device though).
So it's weird: it looks like a SGS2 hardware problem, but on the same time it has a different problem on a different computer. It's really confusing...
Thanks for the quick reply by the way

Then please explain me how I could ever do that when there is no working ROM on my phone. I'm stuck on the 'restore with Kies' screen, like I told in my post (yes, still). And how it will ever work with ODIN? It won't...
Now not any computer is connecting with my sgs2. It just doesn't show anything (not even unknown device). I'm going to try to buy a new cable. Is it needed to buy a Samsung cable? Because it's harder to find than just a regular usb to micro usb cable (and more expensive ). This is my last hope. When it's not working, I need to send it to Samsung.

You need to replace your usb board within your phone. New part can be found on ebay for around $10. It's a really simple task replacing it. No soldering or anything.
It's been well documented on these boards.

[Q] Galaxy SIII USB Connectivity Issues

Hey everyone, I have a Samsung Galaxy SIII (LTE Version) and no matter how hard I try I can't get it to solidly connect to my computer!
What happens whenever I plug the Galaxy SIII into my PC (Windows 8) is a follows:
I hear the device connected sound from my PC and the charging indication from my SIII. So far so good, but most of the time when I go to "My Computer" the phone isn't listed anywhere. After a couple of times plugging the USB cable in and out it shows up on the PC, but almost instantly after being listed I can hear the device disconnected sound and the window closes. If I move the cable for the SIII even a tiny bit I can hear the device connected sound almost instantly followed by the device disconnected sound and a message from Windows telling me that the USB device malfunctioned.
This makes the task of copying photos or movies to and from the device near enough impossible. The phone is only a few months old and is completely unmodified! The USB cable is also the stock out-of-the-box one. This doesn't seem to be a new issue either! It's been happening almost out of the box but I assumed it was down to drivers (which were updated but made no change) and now it's starting to annoy me very much!
Any help would be much appreciated

Basic troubleshooting required.
1) Change USB port on the computer*
If not resolved
2) Change USB Cable**
If not resolved
3) Test on another computer***
if not resolved
4) 2+3****
If not resolved
5) Factory reset the device*****
If not resolved
6) Send for repair******
* If resolved, dodgy port on computer
** If resolved, dodgy cable
*** If resolved, driver / OS issue
**** If resolved, probably was cable and driver/OS
***** Issue with phone settings / data / corruption
****** Faulty hardware (phine)

I'll be sure to give these a shot! Thanks!
No probs.
Beware if you dont know already, factory reset wipes your internal sd card. Maybe use dropbox to auto upload all your photos before you get to that stage.

Alright, so I went digging in the cupboard and found the cable from my old Xperia Play. Upon using that as opposed to the one Samsung shipped with the phone, the connection issues seem to have vanished. (I'll update here if they return)
I suppose this goes to show badly made the stock Samsung cables are which is quite a shock considering Samsung expect people to rely on them.
The cables are crap. The s3 has built in stability detection. If connection unstable with cable, lowers charge to 100mA.
Almost all the "slow charging" threads are down to crap sammy cable

Ha! I was also suffering from really slow charging with that cable! Again though, thank you for your help
I had the same issue, new cable did the trick!

[Q] Unable to connect to pc (no it's not a driver issue....)

Hi,
Having a problem since a few weeks with my s3.
Normally i could connect wiht my phone to any pc,, without any problems. Either it be unix, win, whatever...
Suddnely it stopped working, only thing that happens is charging when i connect it to my pc. Different cables tested, original one, etc..
Connecting it to different pc's resulted in a no go.. so it must be phone related.
No windows pop up, or anything!!
So I figured: Let's install a new rom.
Tried ultima 15 rom, got a different CM rom now (sentinel)... all to no avail.
Is it possible that this has something to do with my radio?
rom info:
android: 4.3
baseband: CEEMG2
Anyone have an idea what to do? Even ADB push ain't working..
See your identical post
I experienced the same problem when m using the Galaxy Nexus S But it was solved by using the app from play store named SD booster... In this app m just set the value of sd card to 1024 give root access and Boom my phone is connected as normal
If this not help then i seriously recommend you to replace the charging port of the mobile through samsung outlet
Go into developer settings, some ROMs may have different ways to get into develop er setting and after you get in make sure USB debugging is enable ^.^
Sent from my SPH-L710 using XDA Premium 4 mobile app
Usb debugging is not required for phone to pc connection see basic faqs and guides .
But as OP has ruled out drivers and cable that only leaves the phone so its worth trying .
Usual replies are
Drivers
Cable
Dirty USB Ports
Not connected to main-board usb port .
I had same issue with my Galaxy SII and when i took it to service center they said mother board needs to be replaced.
So after that SII was good as new.
Got same problem here.
phone is charging over usb , but no data connection (tried different usb cables, different usb ports, different pc etc) but nothing..
also.. tried in download mode and so (after reading forums..) but without success.
then i decided to dissasemble that phone and look, what's inside that beast
cleaned usb port (inside, with contact cleaner), resoldered all pins and etc..
reassembled it back to one piece again and still, no data connection, but only charging
so, here i am, what to do next ? change the usb port on motherboard ?
(visually, everything looks right, good solder points and etc.)
Thanks, Martin

if anybody interested:
i've got it working again :victory:
basically, the problem was the hard way (crap usb data connections on motherboard)
soldered new ways for data+ and data-, and now it's back alive again...
(pictures of ways in attachment)
Martin
see you fixed it already but a note to others :
try using usb port right on the motherboard instead of the case front panel usb ports.....connecting to the front usb ports didn't work for me on some roms, but the rear one always connected so I just have a long cable running out of the back to connect my phone and it works on all roms I've used so far
Nice work hani93, i unfortunately do not dare to desolder and solder this stuff
I've noticed another thing though which is weird!!
When i tried to charge my phone via the power charger (the ac one?), when i check my battery view it still says that i'm charging via USB.
I don't think this is correct, i thought it should say AC or something and when charging via USB port on pc it should display USB?
I think this might be one of the issues that it's also not popping up on the computer.
Anyone know what is causing this or someone can confirm that when charging via power supply it should say something else then USB?
Just confirming your question when charging by PC it says (USB) and when its charging from the Mains it says (AC).
hmmm... guess it must be a hardware issue then?
Either usb port or mainboard... christ...
open it up and cleaned the contacts a bit of the usb port...
Still not functioning..

try to go into Download mode (volDown+Home+Power) and then connect usb, same situation?(eg, no data connection to pc ?)
if nothing again.. try to clean usb port inside (where you plug usb cable), sometimes there is dust and etc. then it stops working.
also, how did you clean contacts on motherboard ? i suggest to take soldering iron with clean bit, and drag iron along the pins.

[Q] Computer not detecting Gear S

Hello, I am having trouble with my computer recognizing my gear s, and yes it has the USB debugging option checked. I have tried on my Mac and my PC-Windows computer. Is anyone else having this issue..or does someone know a solution?

A - 85%. The usb cable is not compatible or is defective. I have 5+ microUSB cables that are known good charging cables but they don't work for data. They are like that by design as they are for charging only, they come with things that will never use a data connection, such as a battery powered keyboard w/rechargeable internal battery or bluetooth headphones that only adopt the microUSB connection for power but look just like every other microUSB cable.
B - 10%. No drivers installed*. Have you checked down by the clock in windows to see if its trying to install drivers? If its an older PC where Windows Updates are disabled and the pc is set to not look online for drivers, this is possible, but highly unlikely since it doesn't work on the MAC. Also, usb debugging isn't needed in most cases. Even with that disabled, you should still be able to see the watch and the 4 basic folders.
*in the highly unlikely event that you really do need windows drivers, download here.
C - 5%. Have you messed with the watch before? eg; rooting or anything like that? If so, its RARE but has happened where in 1/30 cases after trying to flash something or rooting that the watch becomes unresponsive to data on the usb connection. If thats the case, rebooting into recovery mode will very correct your issue.
There ya go..... in order of probability.
I also have quite a few of cables. The ones that I use for data I have them marked. As stated by cipher.....cables might look the same but don't function the same.
Thanks

Phone wont connect to computer via USB

For some reason my phone will not connect to my computer through my USB. I have tried everything and my debugging is on as well. yet still it does not connect. It charges the battery very slowly with USB, much faster with wireless charging. Adaptive fast charging does not work either.
No contact even with Odin via download mode. Have all the drivers and have tried different USB cords.
When you do not make contact with Odin, is it the hardware that is broken?
Have tried different roms in my phone.

Buy new cable because original samsung are defective. They work ok when charging, but usb data transfer is a hell. With new cable it works perfect but I am so disappointed with samsung. We have 2 s6 edge (32 and 64gb versions) in house with same cable issue ( I previously owned 3 S tabs and galaxy s, s2, s3 mini, s4, s5 mini and now s6 edge)...This is really really disappointing from Samsung. After S2 they started making lousy mobiles (s4 was ok)........Will not buy Samsung again!!!
