Hey guys,
Suddenly today my USB stopped working (only charge, no mass storage). So i thought that the device might be bricked so I tried following this guide:
http://forum.xda-developers.com/showthread.php?t=751265
But USB is not even recognized in FASTBOOT, so I dunno where to start. I'm thinking that it might be a hardware problem.
My problem is identical to this thread: http://forum.xda-developers.com/showthread.php?t=1678512
Any help would be greatly appriciated.
Bump
It once happen to me but afterwards I findout that it was a problem with my data cable.
I hope it might help you.

Happened to me too. Had to replace the USB board.
I have the same problem, searched the same forums but it did not work... tried with another laptop, tried with two other data cables, but still not working... I feel it must be a hardware problem...
Now for flashing ROMs, I remove my SD card and plug it directly into the laptop to save the ROM...

You may try and clean the USB-port on the Legend. It does accumulate quite a bit of dust over time and may prevent good contact.
I got a replacement unit after 15 months because of a broken camera and noticed that the usb cable fit much tighter and went in quite a bit deeper than on my old Legend.
A needle should work just fine. =)

Seems like the USB port for my X10 is not working. Last night I found myself having to wiggle the usb cord a bit to get the phone to detect but now it just won't detect at all. I've tried restarting, taking the battery out, using different cords, connecting to a power outlet and to my computer to no avail. Anyway to fix it? My immediate guess is to just take the phone apart and resolder the USB port but I'm not sure. Any input or tips would be appreciated.
Thanks.
Same here USB dead not charging neither communicates with pc
I'm having the same problem with my SGS, after updating to froyo. Very frustrating

Send it for repairs.
same problem here
I have the same problem, cant charge/connect since 2 days. Didnt do anything wrong with the cables....
solutions are welcome, sending for repair can always be done, but i prefer another solution, so i dont have to miss my phone for weeks.
how do i fix the "Usb not recognize"
Did you install the Samsung drivers?
nope, but i know this is a problem with rom? cause yesterday it's fine but when i reinstall bionix usb can't recognize now... what should i do?

But CD ROM on Vibrant?? how to remove this?
USB not recognized - how I fixed my problem
I've been beating my head over this for about a week. I've installed/uninstalled drivers a dozen times, cleaned the registry, deleted application data, etc.
The puzzling thing for me was that it had worked reliably for me at one time, and I had gotten it to work on a couple of other occasions through all of the gyrations above. The phone also works fine on another computer. WTF?
After a fair amount of googling I pieced together enough to start questioning the integrity of the USB connection. Some people said using a different cable worked, others said plugging into a different USB port worked.
What worked for me was moving the USB cable from the front panel connector on the computer to a back panel connector (soldered directly to the mother board). As I said before, others have said changing cables worked for them.
I suspect that the phone's USB signal integrity is marginal (possibly bad impedance matching). Add to that questionable quality control on cabling inside and outside the computer.
Anyway, try connecting to a different port on the computer and/or changing your usb cable.

Sorry, I missed that you had fixed the connection issue. No, I don't have a fix for the CD problem.

Fix USB Device Not Recognized
I went through the biggest search to try and fix this issue. Connected my Vibrant on different computers(different OS's) and found not a single solution along with drivers. Tried different usb cables and nothing but the same error. Look inside the usb port of the phone.....ah ha!!! small amount of lint managed its way in there and stuck to the pins. I was able to charge so it never occurred to me up until last night when I wanted to put in a new ROM. I used a thumb tack and carefully cleaned the port( REMOVE THE BATTERY FROM THE PHONE BEFORE DOING THIS!!!)
Also make sure the cable didn't suck up some of the lint too. this happened to me too.
Good luck
Hello, guys.
Well, I have MiniCM7-2.2.0 on my X10 Mini Pro, and the rom is perfect, except for one issue: the phone is not charging anymore.
It's been some days since I plug the cable on the phone and it does not recognize it. Them, I have to reboot the phone, with the cable pluged, for it to be able to charge. Sometimes, even rebooting it won't fix the problem, and I stay with the battery off until it magically star working, after a thousand times.
What can I do?
I have searched the forum, but found no similar threads.
Sorry for my bad english. Hope you can help me.
ok first things first, change your rom and kernel, and if that doesnt work change your cable, and if that doesnt work it is your usb port that is stuffed for your phone, because i have exact same problem, dont keep trying because it will make your usb port smoke, literally it has happened to me ! if none of those work, you'll have to buy a external charger about 4 bucks off ebay hope i helped

I've tried with 3 or 4 different cables, and the problem continues.
Let me try re-installing the kernel and rom and see if that works.
If doesn't work, I don't know what i'm going to do, 'cause there is another issue, besides the charging problem: the memory card. I can only access the files through the usb cable. How will I move the files on the memory card?
Anyway, thanks for the help!
Urghh maybe your USB charging port got a problem?
A month or two ago I started experiencing problems while connecting my S2 to the PC or laptop using the data cable.
When I connect the cable to my S2 on the PC or laptop it comes up with the balloon messages in the system tray:
USB device not recognised.
Then a short while later it comes up with another balloon message:
This device can perform faster.
Sometimes while transferring data, it will disconnect and the file transfer fails.
Sometimes if the cable is moved slightly it will cause the device to disconnect from the PC.
And, of course, the file transfers are much slower than they should be and much slower than they used to be.

I haven't touched any ROM or flashed anything on this in like over 8 months so it's nothing to do on that front.
I removed micro SD card and tried reconnecting again, still the same problem.
I've tried different computers, still the same problem.
I've used different cables, still the same problems. Tried enabling and disabling USB debugging. Same problem still remains.
The USB cables and computer and laptop work fine with my S3.
All the correct drivers are installed for the S2.
I'm resigned to thinking it's a hardware issue as I've exhausted other options. Is there a simple fix or will this need sending back to Samsung?
I've had the phone over a year now but someone told me the warranty is two years?
All help appreciated guys. Thanks in advance.
Why don't you upgrade to ICS?

Probably because his USB port doesn't currently work properly.
@OP, this is often caused by a dirty or faulty USB port. You can try cleaning it, but you may need to replace it.
Try cleaning it out with a dry toothbrush first.
If that doesn't work, take the battery out, and try cleaning the port with a small q-tip with a small amount of isopropyl alcohol; let it dry for a while after that, then replace the battery.
If THAT doesn't work, you'll probably need to replace the part for the USB port.
If your warranty is still good, you could try to go that route, but you'll need to unroot your phone. Otherwise, I've heard it runs about $15 for the part, and you can replace it yourself. If you don't feel up to it, you can have a cell repair shop or Samsung service center do it for you, but it will probably be significantly more expensive than $15.
My opinion based on your description is the USB socket on the phone is wearing out/damaged. The USB socket is on a small circuit board separate from the main logic board. It's easy to replace and the part is cheap on EBay. Search for a disassembly/tear down video and judge whether you can do it yourself.

Thanks for the very quick responses guy. They were very thorough as well.
I will look into cleaning the port and if it still doesn't work I'll consider having it repaired. My soldering skills were excellent but I haven't done it for a few years, so may leave it in someone else's hands.
I haven't upgraded to ICS as I was very happy with my phone at the time. Also, a couple of friends who had upgraded to ICS on their S2 regretted it due to numerous problems, which put me off upgrading.
You can still use mobile odin and theres no soldering needed with the usb,it comes as a board with a ribbon cable.

I've had a look on the Samsung website here:
w ww.samsung.com/uk/support/warranty/warrantyInformation.do?page=POLICY.WARRANTY
It seems as though the warranty period on my phone is 24 months so I might just get it done via Samsung.
I'll contact them in the morning and see where I stand. If not, then the replacement USB board connected by a simple ribbon cable sounds like a doddle. I've seen a grade A condition part on ebay for about £8 delivered.
Thank you once again.

This is a Cable problem. The USB port of your device is wider now, that's why the cable doesn't fit well. Buy a micorUsb cable for blackberry, it's always very full and thick, then use it to connect your phone. The issue should be resolved.
I once had the same problem with my Nokia N8 and using a Samsung cable (which looks fuller and thicker) solved it.
Yeah warranty should be 2 years BUT youll have to unroot it first if your sending it to them.
They may also wipe your phone and stick on 4.0.4.
If you get the board yourself,check the number is going to be the same i.e the spare one I have here is GT-I9100 rev2.2.
Also other people have got a replacement board and the mic doesnt work(think the boards are sold as refurbished).
So its up to you which option you go for.

Hey all,
I thought my USB port was broken given that it didn't charge and I couldn't connect it to the PC.
So I bought a nice one and replaced it.... no dice. Still doesn't work. However, the odd thing is, I also bought a USB jig and that does work. Anyone got any clue what could be going on?
Cheers
Maybe the wrong USB board, there's a couple of different ones, best way to work it out is match up with the one already in the phone. Search for similar threads in Q&A over the past few mths; there's been detailed discussions (and pics from memory) of which board is which.
Check on this thread.....

As you said that even after replacing the port.... it didnt work. And it worked out after you connected it to your new USB jig. This means that there might be a problem with the original USB wire which comes with phone when you Buy it. It might even be a problem with the Connectivity Board in the phone as it must have been damaged. I'm not really sure about this but it might even be a problem with software... Maybe you should have tried to atleast wipe the whole system... maybe then you would get to know more about the problem.
Cheers
heh, yeah, I did check that and ordered a 2.2, but they sent me a 2.3.
However, I stuck my old 2.2 one back in, and tried it with the jig, and the jig works :S
So no my USB doesn't work, but the USB jig does... that's really got me confused
EDIT: Yeah, I did think about software, so I tried to install a different ROM and then I got scared and thought I bricked the phone (it didn't like that wrong USB version was there I guess). I'll see how that goes.
I tried a different cable. The weird thing is it sort of slowly died, and I had to stick the cable in at a weird angle and stuff, so that's why I thought it was the USB port.
As I understand it, there are 5 (?) connectors in the socket. Each connector when paired with the common or ground contact (probably the shielding on the outside of the socket) will perform a different task (that's probably an over simplification of the sockets functionality.........but you get the idea)....eg/ data transfer in, data transfer out, charging, jig resetting, usb docking, usb otg.....that sort of thing.
When you get the situation you're in, it simply means that the relevant connector for the required task is damaged or worn out.....but that doesn't mean that ALL the connectors are affected.... ..that is why some functions work while others don't.......
