So I was hoping some of you guys could help me out.
Recently my Vibrant started to give me trouble with my computer. But it's only my vibrant with my computer. I can connect to any other computer no problem. Any other device is easily recognized by my computer except the vibrant.
It started after using PDANET's tethering app. I was at one point tethering all the time putting my phone in usb debugging mode and running pdanet on my computer. Then I also started using the bluetooth tethering. Once I finally got internet at my new place i stopped using the tethering option. But then I realized when i tried to get files off my phone my computer wouldnt recognized my phone anymore.
The error I get is
USB Device Not Recognized.
One of the usb devices on this computer has malfunctioned and windows does not recognized it.
Usb Root Hub Unknown device.
Try Reconnecting the device if windows still does not recognized it replace the device.
In the device manager the properties of the "unknown device" says
Status: Windows has stopped this device because it has reported problems. (Code 43)
I've tried the solution posted under here
USB Fix - Win7 x64 - USB Device not Recognized
and I've used both drivers from Samsung Kies and here
[Drivers] MS Windows x86 and x64 USB Drivers for Samsung Galaxy S
(Sorry can't post links apparently)
When I try to update the driver manually for the unknown device it says that it has already selected the best driver for the device. So i don't know if it really updated it.
Any Suggestions would be really helpful. Thanks!

I have the same problem on my PC. I would plug in the phone and my mouse would stop working. No tethering app installed or anything.
Anyway, I just tried the ports on the back of the PC and those worked. Try a port closer to the MB
I've tried all my ports. It's still not recognized.
Check the cable and power source. Be sure cable is with good quality. I hade the same issue. I fixed it with original HTC cable and back panel USB from my deskop computer. Front USB of desktop computers often are not enough to power that consumption.
After updating to Froyo it started working again. Thanks though. I still have no clue what caused it.
Bumping to confirm, I found this thread after getting the same error. I had tried several of the USB ports on my computer but after reading this tried the 2 I hadn't yet, they both worked. Not sure why only those work now, but they do work.
Hope this helps someone.
I have a bricked galaxy s which doesn't do anything. Windows 7 reconizes an unknown device and it's not possible to install the samsung driver. Windows says that it allready has the right driver.
I can't seems to reincarnate my galaxy s. Only this small sign of live in windows 7.
It happened when I was flashing 2.3.5 and the connection went down just seconds after the start of flashing so I guess the bootloaders are corrupt.
Anyone any idea how to solve this one?
Vibrant UnBrickable Mod
The same thing is happening to my Vibrant. Tried Rooting and installing various ROMs and it is still "Not Recognized". Tried all ports on all PCs (4) and Laptops (1) and non of them work. espy1988, how did you upgrade to Froyo 2.2 if you could not connect to PC and Kies? This used to work without an issue.
Thanks

have u tried Odin back to stock using Odin or hemidal ?
I have the same problem now. I have had my Vibrant for over a year never with an issue. I have Odined it back to JFD dozens of times but now it will not recognize the usb device.
I have GB bootloaders, but never a problem before. When changing Roms I usually Odin back to JFD first and start clean.
My problem started with the phone getting stuck in landscape mode. I was running a 2.3.4 GB rom Sensation. I reflashed a few times but whenever a restored anything from Titanium it would revert back to landscape only. I decided to go back to a 2.2 rom and plugged in the phone to Odin and it was not recognized, also not as a mass storage device, no go. I used Samba to copy a 2.2 rom, Trigger, to the phone and flashed from there. The phone is good now except the computer still won't recognize it. I can use Samba to access the SDCard but I hate not being able to use Odin if things go south. Tried all usb ports and a new cable, no go. Really wierd.
Looking for suggestions......
If you're still under warranty claim it & send it.
Had same problem. There is no fix short of replacing USB port.
I found my problem. It was dirty/corroded usb port. I carefully cleaned it out (took a few times) and it's all functioning again. I also cleaned the contacts on my original usb cord and it is working again also.
I'm just now having this problem for the first time. I've tried all USB ports and cleaning the port on the phone with no luck so far. Can someone point me to the unbrickable mod mentioned early in this thread?

Have you tried installing the installing/re-installing the Samsung drivers (LINK), using another USB cable, or even another computer? I just want to make sure you've tried it all before attempting to do a hardware mod.
Anyhow, you can find a link to the unbrickable mod and other hardware mods in the "Official XDA Vibrant Bible Thread", under the "MODS/SCRIPTS" section (LINK).
Mine is the cable btw. My wife has a GSII and I was able to use her cable.
Hi.
I wanted to update my x10 mini pro to the latest firmware. It didnt work throught the updater, it said I had the latest but I didnt (i had Baseband 006 - kernel 2.0.A.0.504). So I followed this rendeiro2005 "[FLASHTOOL GUIDE] HOW TO for n00bies" I downloaded the nordic version, but nothing happend, tried to update it but still said there where no updates. So then I downloaded the UK version, then It found the new update, it worked halfway through the update and then the computer died.
Now either nothing happens, I mean it doesnt find the phone via usb, or the computer dies. I tried to uninstall/reinstall PC companion with revo uninstaller, didnt work. Then I tried to start the computer in safe mode and that didnt work either. And I have tried all three different ports. I tried to turn of the phone and connect it and then the computer snap shutdown. (the usb worked fine all day today before I tried to upgrade).
Thanks
Now I¨ve tried to uninstall flashtool and the drivers installer that comes whith it, also uninstalled PC companion. And used the guide "how-to-remove-old-unused-device-drivers-in-windows-7" to deleted some drivers that I suspected have something to do with the phone. At least the computer doesnt die now. But still it doesnt find the phone when I plug it in. I tried the "silent mode trick", but didnt work either.
I dont think theres something wrong with the phone. I did a backup with titanium before but I cant get to it now since the phone isnt rooted anymore after the FW update.
Do you have the Debugging mode enabled? if you have it, try disabling.
Ya tried that to. No success. Even formatted my computer. Nothing. Then I wanted to charge the phone, ordanary rechargeching, that didnt work either. So it must be something with the phone. Have no clue how to get around it. Tried hard reseting it also. Nothing. I guess is something with the new firmware upgrade. Is there any way to go back without using usb?
Is there a way to update/downgrade it wireless?
If the usb is broken, can I send it to SE and have it repaired? (The phone is secondhand without reciept)
You can send it to the SE care centre to get it repaired but you will have to pay because it is out of warranty.
regarding your pc, does usb work other than your phone? im wondering how a connection like that to the phone makes the pc go dead!
There maybe something with the pc or the phone. check with the hardware wires are connected properly and try some other usb device (pendrive etc) and check if the usb works well. then you dont need to doubt about the pc next time.
if pc works then you have to check with your phone and see if that doesnt work.
Other than that i dont know if it will be software (windows xp,7, or other s/w) matter but something on hardware. doubting the phone. so please check it out.
Thanks and good luck on your search!
Do you know how much it can cost to get it fixed?
Ive tried to reinstall windows, didnt work. Tried linux, didnt work. Ive tried other usb devices and they work. After reinstalling the phone doesnt kill the computer anymore atleast. So I guess its the phone. I wont charge when its of either.
Everything worked fine halfway through the update with pc-companion. After that the phone lost connection and never got it back since. What do you think, any chances?
I am owner of the Galaxy S2. I updated yesterday to SuperNexus Jelly Bean ROM, didn't liked it. I restored my device to CM9 which i was using for a month without any problems. Then it started, computer couldn't recognize the phone anymore. Its like that SuperNexus broke something i don't know. I reformatted my Win 7 Ultimate x64 and installed fresh new CM10 - but after all my computer and S2 don't like each other - USB device not recognized. Chaos. I asked my friend to come over just to test with his S2 (he's on stock ICS 4.0.3 or 4.0.4), and when i plug his phone into my computer, everything works flawlessly. I tried mounting in recovery, i tried with and without usb debugging, Odin doesn't find phone neither, tried updating drivers - no luck... Dialing *#7284" just gives me "connection problem or invalid MMI code". Need help on this please!
You can check THIS thread. The one HERE , and also THIS thread.
I've read them all, tried every advice, but phone still isn't reacting to anything. So my problem is that phone couldn't connect to a computer, well it connects but it states "USB device not recognized", it charges but that's all. Everything started with Custom ROM SuperNexus. I've done these steps so far:
1. Reformatted my computer OS, which is Windows 7 Ultimate x64
2. Downloaded CM10 over my phone, get into recovery --> factory reset, wipe cache, wipe dalvik, format system, install ROM, wipe cache, wipe factory
3. I tried on my computer, tried on my old computer with Win XP x86
4. My friend's Galaxy S2 is working like a charm with MY cable on MY computer, which makes me believe that there is some defectiveness in my phone
5. I tried cleaning MicroUSB port with tooth pick, ear-cleaning pick (or how do you call it), needle with some paper wrapped around it, tried blowing in it
6. I tried with different USB ports, front ones, USB 3.0 - still no luck
7. I tried flashing Wanamlite and Neat ROM-s, still the same problem
I'm using Airdroid now, but i really need to know what's the problem! I have already ordered a new parts on E-Bay and I'm having high hopes about that solution. Im not able to post link to E-bay item, but search it under Item Number: 150904945773. Any other advice is really highly appreciable. Thank you
Try downloading the Rom over WiFi, or Hardline instead. Have you tried a different USB Cable ? Also I'm not able to check that Ebay # right now.

eBay item is this: New Samsung i9100 Galaxy SII S2 Charger Charge Port Flex Cable Replacement parts
OP, I'm hoping it works for you. You seem to be going in the right direction with your troubleshooting.
Well, i've downloaded this ROM (CM10) via WiFi, now i can do it over Airdroid too. But is there a way to flash Stock Original Samsung ICS in recovery? Or is it only available in Kies and Odin? I came across "Mobile Odin", do you guys have some experience with it, is it safe to use? How big are chances anyway that USB will work with stock ROM? Someone told me "your USB port on phone is OK, if it's charging it's not broken", so I'm thinking that it is not a hardware issue after all? And BTW i used several cables, and three different computers. My girlfriend have SGS3, i tried it like 2 hours ago with her cable on her computer with no luck (and of course her phone have no problems to connect to that computer using that cable). Thank you
I would try a Stock Rooted Rom, and see if that works correctly. If not try connecting the Device, and reboot the PC with the Device plugged in.
How to install stock ROM if i cannot get Kies or Odin to recognize phone? Via Mobile Odin?

Try USB solutions from My Android Solutions or Mobile Odin like http://forum.xda-developers.com/showpost.php?p=28302093&postcount=4789 ( procedure is same but written for Korean SGS 1
Guys let me tell you that I'm grateful to you, cause this Mobile Odin worked and my Stock Rooted ROM worked in connecting with PC. But not on first try when i got into a newly flashed Stock Rooted Firmware, i've let it to do his stuff, update what he needed to update blahblah. Then i tried to connect my cable - it didn't work. I cursed, i cursed so bad. Then i considered to give it another shot, rebooted the phone - and voila! Everything works, i tried 2-3 times and its working. Obviously SuperNexus started my problems, they couldn't be repaired by any other ROM i tried (i tried CM9, CM10, Wanamlite, old Wanamlite with MTP enabler, Neat ROM)... Then with Mobile Odin everything just worked. Dunno what really was the problem. Thank you all
Glad you got it sorted

I put a stock sammobile I9100 xwlse 4.1.2 jelly bean rom on my Galaxy s2 worked fine for 2 days now I have problems charging the phone saying after half an hour its charged when its not also windows 7 will not reconise the device anymore tried factory reset still no joy even when I unplug the charger or plug it in its go's slower to start charging or stop chargeing its annouying the hell out of me tried on windows to uninstall the drivers and reintsall to no avail any ideas
Ok first of all, punctuation - use it.
About the battery problem, it seems like it's out of "sync", you should let it from exactly 0 to exactly 100. That should fix it.
About the not recognizing, have you tried different USB port on the PC? Tried on another PC? Tried with another phone? Tried with a different USB cable?
You have many options, now go try them.

I am having a similar issue, when I plug my phone into a windows PC through USB the MTP driver is buggy, have to reconnect and change to media device a few times until it installs, and then the issue afterwards will be the phone will seem as if it is being plugged and unplugged multiple times after its been disconnected (usually when I have media player running too) ... this issue was non-existant before the software update so I'm sure its gotta be an issue.
comas & latest kies.

The thing is that it doesn't make any sense
You are not rooted are you?
Your usb flex must be dusty/busted.
Nope not rooted tried uninstalling drivers and reinstalling even tried Keis not a thing I get error code 43 on my pc even though the drivers are there it says usb device not reconised so for some reason which is doing my head in I cannot get it to connect with my pc on windows 7 also tried it on another computer with XP on and get the same problem tried driffrent usb ports and usb leads as well
Error 43 is a start.
Disable the antivirus and don't install the drivers, install kies.
Try a laptop.

Hello,
I have a very big problem with my Samsung Galaxy S3 I9300.
The problem started when my battery ran down very very fast. I can use my phone for no longer than maybe 6 hours, and that is in stand by. If I want to charge my phone till it's completely full it might take two days on the charger as well, even when my phone is off. I tried to reset my phone to factory defaults, but that didn't fix the problem. I even bought a new battery, hoping that would solve the problem, but even no luck with that. The phone also becomes hot in the bottom. Now I wanted to bring it back to the store for warrenty but there lies the next problem, my phone is rooted.
I know it is possible to unroot the phone, and it's nog too hard to do. But every time I connect my phone with USB to my computer, my computer doesn't recognize it. I get the next error message "USB device not recognized". I tried different cables, I tried on an other computer, but still I get the same error. I also tried the S3 of a friend on my computer and with his phone I do get a connection. So I know there is nothing wrong with the drivers on my computer or something like that. There must be something wrong with my phone.
Now the problems won't stop here because there is even a third problem. Like I said before I have rooted my phone, but I can't use SuperUser. When I start SuperUser it says "The SU Binary needs to be updated. Continue?". Then when I press continue I get the message "Installation failed !". I can't use CWM as well. I wanted to use Triangle Away before bringing it back for warrenty, but I can't use it because I can't use SuperUser.
If some one would have an idea to unroot my phone without using USB so I can bring it in for warrenty. Or find a way to get my USB port running again, I think that would fix my problems.
I spend a few hours trying to fix these problems, but now I've come to a point I don't know what to do anymore, I hope anyone of you is willing to help me. I'll be for ever gratefull.

Hi.
If i was you, i would try to install a official version, using Odin.
Also, my advice is not to use the original charger, Even chinese have better one´s...
Did you install Kies and drivers on your PC? Check that too.
Consider install leaked 4.2.2 version of Rom, since it uses Odin to do it.
I hope i gave at least some clues....

Thanks for your reply,
I forgot to mention that I have the official ROM installed, I only rooted it. But even if I would want to install a new ROM, my computer doesn't recognize my phone throug USB. So I can't install a ROM using Odin unless my USB port is running again.
I tried several chargers already, I don't think the problem lies in the charger because the battery drains very fast when it's of the charger.
I did install Kies and drivers, I even uninstalled them and reinstalled them again a couple of times. I even tried it on different computers. And the Galaxy S3 of a friend of mine does make a connection. So I don't think the problem lies there.

Hummm....
Did you try hard reset? Definitely without USB recognition, you can`t go to next stage....
In setup did you check optinos like USB debugging?
At this moment im out of options....maybe a poweruser can help you better:highfive:

What exactly do you mean with hard reset? If you mean powering on with home button and volume up button pushed, and then select "wipe data/factory reset". Then yes, I tried that.
In setup I did check USB debugging. The thing is, when I power on with home button and volume down button, I enter download mode. But even in download mode my computer does not recognize my phone. I'm not sure, but I think the computer should.
I'm really stuck here :crying:
