So I have a Galaxy S 4G that I can not get to be recognized by my computer via USB. It charges fine but always get "USB device not recognized". It's on stock froyo and I have tried several cables and computers as well as versions of drivers so I assume it's a faulty usb port on the phone.
I looked at this thread : http://forum.xda-developers.com/showthread.php?t=1099374
And it seems that it was possible to flash cwm from recovery and then flash a custom kernel that gave root access? But links have been removed and thread closed and replaced by one that requires gingerbread. Does anyone know of any way to root on froyo without usb cable? or have the files that were removed from the thread above?
Any suggestions at all?
Fix your USB port.
try heimdall?
Visit your local library and use a computer there to root. Having fun isn't hard when you got a library card.

Most free-to-the-public computers are so locked down that I doubt he'll be able to get drivers installed.

The ones in smaller towns usually aren't, or their security is easily bypassed with ctrl-alt-delete or similar combinations
thanks for the responses but it seems that I need to clarify that it looks like it's the usb port on the phone that is defective and not the computer. My Galaxy s3 and tab 7.7 connects just fine with odin using same computers and drivers that I can't get to recognize this phone.
And yes I did try heimdall but since the computer does not see the phone heimdall won't either
Nothing else I can do to get root? I would not mind about being stuck on froyo I just need root to install vodoo sound.
^ How do you charge your phone if your USB port is busted?
If it is charging well, then I suspect there is a conflict in drivers.

If the power and ground pins are active, it will charge, but if the data +/- pins arent' connected, you can charge but not transmit data. My USB cord did that to me, will charge, but won't show "usb mode" to connect for usb storage. Thought it was the rom, flashed 4 times, realized the cord must have a break in the VCC+/- wires.

hi. i'm having problem in connecting my device in bootloader..
i used to be able to connect with PDAnet in bootloader without any problem, but now all i have is "connecting to your phone". I've downloaded the USB driver package from the sdk but still no luck..
any idea ?
*yes i search the XDA forum and try following the guides but i still have no luck*
have you tried the connection on another computer?
sometimes the computer USB ports tends to go crazy and wont work with the device no matter what
there's an utility (forgot the name) that lets you delete all the bugged USB associations in the PC
if you can find that, then you can try it as well

Hey. My captivate has been working beautifully with these new GB roms until about a week ago when my computer won't even recognize my phone. and all the phone shows that it charging but no notification about USB connection? ive tried different ports and reinstalling drivers all that good stuff and restarting my computer and turning on and off usb debugging and the cable still works with other devices so can anyone help?
Also can you tell me if samsung will replace my phone with a custom ROM on it? im thinking of doing this because i cant flash back to stock without the USB working!
Are you sure the cable is 100% functional? What other devices?
Try plugging it in to another computer as well

I have had that problem on a few gb roms too. Go into USB settings and change them to kies and then plug your phone into the computer using your USB cable. Just leave it plugged in for a few seconds, you don't have to wait for your phone to be detected. After unplugging the cable, restart your computer and phone. Once both are running again, go back into USB setting and change them back to USB storage and then plug your phone back into your computer, making sure you use a USB port directly connected to your motherboard. Works for me everytime.
Edit: If you suspect that your USB cable is not working, see if Odin will detect your phone in download mode. Don't flash anything, just see if it says connected in Odin.

it didnt work if i just go to samsung and give them the phone with the custom rom on it what would they do?
Download kies and see if your computer will detect your phone in kies mode. You could always get an SD card and put all the files on the card then move them to your internal SD. If you have a custom rom installed you can flash stock using cwm. Did you try connecting your phone in download mode to your computer running Odin??? If it doesn't detect it then your USB port is not working or your USB cable is broken. If it is working flash stock and start again. It could be a bad flash.
i have had the same problem a couple days ago, plugged in another captivate into my computer it recognized it. then plugged in my phone and everything was working fine again.
try plugging in anothe android phone running froyo or whatever version you have
Can you get your phone into download mode?

Sounds like it could be, try plugging it into the back of the computer and see if that helps.

The USB drivers for download mode are in the bootloaders and has nothing to do with the USB drivers for the rom. Even if you had a bad flash and the USB portion of the rom was corrupt, your computer would still be able to detect your phone in download mode. See if you can plug your phone into a different computer either at a friends house or at work to see if they can detect your phone with your cable. If not, you will need a new cable.

So what if that didn't work and nothing was wrong with the cable? Would it be my USB port on the phone because the cable wiggles when I put it in.

Hi all,
My Droid charge decided to do something weird today; it no longer will USB mount! This problem is particularly bad because, while I can put the phone in download mode, my computer will not recognize the USB and ODIN (1.2 & 1.8) cannot wipe the phone.
Any suggestions? I really need my phone back, but I'm not sure what to do.
Tried reinstalling the USB Samsung Drivers, using the original data cable, and two different computers (Win7). SD card will mount in an external drive (aka without the phone), and the phone will charge via USB. I have the most recent form of CWM on it, and the EP4P debloated and rooted rom.
Thanks,
frak

That happened to me a while back. Mine had the added bonus of going into desk dock mode and staying there. It was a hardware issue with the USB port. It would charge, but nothing else. Mine did become intermittent though, and cycling the cable in and out seemed to help it some, but ultimately, I had to send it in for replacement

What cable are you using? I accidentally grabbed my charging-only cable the other day and didn't realized it only had the wires for positive and negative. No data pins.
Is it the cable that came with your Droid?
Another thread similar. Check it out and try some.

Had that yesterday. A different port worked fine for me. Maybe a couple of power cycles will do the trick.

Can you point me to the drivers you installed? Thanks in advance.
I am having same problem and going nuts. I have Galaxy S2. I CAN connect to windows and Kies when phone is booted up but can not connect while in download mode. On Andoid System Recovery <3e>, I tried to do factory reset and wipe cache but no vain. Still getting usb not recognized.
so, my phone is bricked, I bought a jig since I couldn't access download mode. The jig works perfectly, but no matter what cord, USB port or computer or operating system I still can't get the phone recognized. I always get "USB device not recognized, it may have malfunctioned...etc." I thought it was the drivers and etc, but my friends Galaxy S works in download mode and gets recognized...I thought it might be the USB port, but the jig works everytime and the charger turns the phone on when plugged in.
So I'm out of options, the unbrickable mod is just not in my skill set, what else can I possibly do?
I know you said it was coming up as USB device not recognized...buy did you run Odin and see if it was there?
Yes, neither hemidall or odin detect it.

I can't tell if you tried this, but when I was flashing with the Captivate and Odin, I always re-installed the drivers. Everytime. I also had better luck running Odin as Administrator. Again, couldn't tell from OP if you did all that, so hope I'm not preaching to the choir

then try to go in download mode u can go in it by
1.take out the battery
2.hold the 2 volume keys (not the power key).
3.put battery inside..
4.then while holding the 2 vol keys plug the usb cable in the phone and to the pc..

Have you tried just putting cable in PC then in reg mode hook to phone...let it find and recognize. Then unhook from phone. then put in d/l mode then hook to computer....then open odin.....
EDIT: the cable that comes with the phone is really not such a good cable...i went out and bought a nice thick one..just casue the sammy one works for charging and USB mass storage doesn't mean it will for ODIN...I ran into that with my Captivate and Infuse...I went out and got a nice thick 25$ cable...no issues...also try a diff port...>?
I swear the op never gets read. the phone is bricked, I can't get past the Samsung screen, I have stock 3e recovery, and the only way to get to download mode is the jig. I have tried kies mini and the exe for drivers but none of the multiple computers ive tried recognize the phone, I have tried several different cords as well, I think my only option is Jtag.

No that's not your only option..... If the phone turns on at all ths sts great, diagnosing kies fire the drivers is crucial first off, then use the jig to get into dl then hook up to computer and open heimdall one click back to stock by Ulster, if heimdall still doesn't recognize it, unplug micro USB from phone and plug back in, again the RIGHT drivers for windows or Mac are CRUCIAL! Just went through a huge ordeal with my infuse thinking it was gonna be dead, if you can get to Samsung letters its not bricked, bricked is if it does nothing....read my last post.

I had to install the 4.3 firmware on my S3 since it got soft-bricked, but it seems that even though I installed the Samsung USB Drivers and installed Odin, my phone won't connect to Odin. I tried using different charging wires and different USB ports, and that doesn't work either. Even my friend's phone, which was an S3 as well, managed to connect to Odin with the same charging wires. Is it something to do with my phone? I need help with this.
My S3 updated to 4.3 (locked bootloader) and I can't make it connect via USB, it won't connect. I've tried everything, every link I can find, reghacks, drivers (countless installs/etc). I know what I'm doing, I've been using computers longer than a lot of posters here have been alive.
The thing is the device isn't telling the PC what type of Hardware it is, let alone the PC having drivers. I actually think my phone is toast - I'm glad it still charges and you can (if you're not rooted) root via Towelroot without a PC.
Good luck.
