try different USB cable
I think you said you did this but make sure usb debugging is enabled. Go to settings, click applications and then click development and make sure usb debugging is checked. You have done everything I would recommend doing. I used to have the same exact issue. My phone would charge but I could not connect to the computer, my friends vibrant connected fine though (weird).What fixed it for me was a new usb cable from the tmobile store, it costs around $15. They have a 30 day return policy, if it doesn't work you can just take it back. I was really close to replacing my usb port on my phone but I figured I would try a cable from tmobile first and it worked thankfully. If a new cable doesn't fix it then you may have to replace your usb port unfortunately. I recommend www.mobiletechvideos.com if you end up having to replace your usb port, good luck.

I also have multiple usb cables but the only one that works is the cable from the tmobile store. All four of my other cables work fine on my friends vibrant too. Like I said in the post above yours, you can always take it back if it doesn't work either. If that's the case then you could try cleaning your phone's usb port with a Qtip and some isopropyl alcohol.

What ROMs did you try flashing?
Does your pc recognizes your mobile connected when in recovery... you have tried almost all possibilities so i have no idea... You can try flashing stock rom and then format(factory reset) whole device...

It's called JFD. If your phone is detected in download mode then you can use this software to return to stock - http://forum.xda-developers.com/showthread.php?t=954509

Try a new USB cable I used a PSP USB cable for a while when my HTC hero USB cable stopped working properly. Just find some more USB cables and test them all.

You probably damaged the USB controller with ESD. You can try another USB port, but it's likely that all the ports are damaged (at least all the ports on that controller). Check the other ports on the PC. Most modern PCs have at least a couple of USB hubs built in. It is possible that a port on another hub or controller may work. Otherwise, you might be able to use a USB add in card in the computer if all the built-in ports are dead. They are relatively cheap if you have the slot in the machine to install one.

mount to PC is a known issue methinks. What is your current setup? Rom/kernel? and how are your settings? USB debugging set on/off? auto connect set to "ask on connection"?

Its common with the 2.2.1 roms. What you need to do is replace the vold.conf, and the vold.fstab files in system/ect. I have attached the ones you need. Just use root explorer and drop them in the ect folder, reboot, and test.

you should download toolbox from development section and the first option is to install drivers. once u run the program. install it and then test the usb cables. by the way i never charge my phone from a computer i like separate chargers so im using the charger for BB to charge my battery. its quicker as well.

Hey, so when I try to connect my GS2 to the computer (via USB), it doesn't connect for some reason. After connecting it, it takes about 5 secs and it starts to charge but doesn't connect to the computer. I've tried a couple of different ROMs and also on 2 other computers and its the same result. I need help please. Thanks
First make sure drivers are installed if so then try another cable that could be the problem.

You are missing the drivers. Search via Google for the hardware ID or simply by the model of the phone.

I have had the drivers installed, and I tried my brother's HTC usb cable and it still doesn't work.
My thread is right above yours. There are USB port issues with this phone. Although I feel for you, I'm glad to see I'm not the only one. If you have insurance take it back cuz it only gets worse. Flash stock while you still can, if you're not already running it. Trust me.

Hey everyone,
I have been having troubles connecting my phone to my computer through USB. I used to have to push the micro USB cord to the side for the computer to recognize it. Now my computer will not recognize my phone at all, but charging through the USB connection works fine. Is there anything that I can try to get my computer to recognize my phone? (I have the drivers and have connected it to the computer successfully in the past) and if there is no fix, then will warenty cover it? I have had this since late October. I am running galnet miui if that helps.
Thanks,

My suggestion is to try another cable. USB cables can be real finicky. Or try a different USB port on the computer.

I did not replace anything - I just cleaned the port and all was good again.
Oddly enough - today it started acting up again. Going to try cleaning it again, if that does not work its time to get it exchanged under warranty.
I get an error saying usb device is not recognized. I tried different cables and pcs how can I fix this?

I hate when i spend hours trying to fix something then i find out its something simple like the cable. so always check the simple stuff first. I have found good cables at cableforge.com with lifetime warranty. so if i ever have one go bad they ship me another. plus use this coupon code for 80% off. G5WJXH4F22MN
I had a mate with this problem with his S2.He tried everything from reinstalling keis to full wipe installing the rom to stock rom and nothing.In the end he solved it by plugging his old i9000 into his PC and when it said it was recognized he unplugged it and plugged in his S2 and it recognized his S2....simple but true.
Try plugging in another S3 or better still an S2 or S1 so the PC recognizes the drivers and then plug in your S3.It may work like it did for my mate.
Use stock ⣔ cable came with your phone
shouldn't need kies. Obviously if nothing else is working give it a shot but I've never had to use kies for anything.

Have you installed the device drivers for your phone? If you haven't I would recommend downloading the device drivers for your phone from here. If you have already installed the device drivers for your phone I would recommend uninstalling then reinstalling the device drivers for your phone. Also, is the usb cable a decent quality cable and are you able to connect other devices to your computer (And Windows recognizes them) using this cable?
Thank you for your feedback and yes ive been through the motions of uninstalling amd reinstalling the drivers multiple times. The cable im using is for an LG smartphone and its in mint condition . It alsocworks with other devices except mine. My samsung would have a usb icon pop up on the phone whenever a connection is made but now it just charges.

You could also try using a different usb cable and also make sure your plugging your phone into a USB 2.0 port as sometimes USB 3.0 ports can be problematic. Another thing you could try that very likely won't make a difference but you could try is going into developer settings and making sure USB debugging is enabled.
Ive tried every usb port on my laptop and i tried the usb debugging feature but nothing seems to be working. I will get a new usb cable specifically for my phone to see if it makes a difference because im running out of options.
