I encountered something perculiar. I plug my phone into the usb cable connected to my PC, the device icon showed up in My Computer and I clicked the gt-9300 icon.
Instead of showing 'Card' and 'Phone' icon, nothing is display. It has been happening to both my pc and laptop randomly. I had already reinstalled my kies and drivers, flashed a new rom and it is happening still.
by any chance has anyone encountered the same problem as I did?
Probably no USB drivers.

If your phone is locked with a PIN etc., then you have to turn the screen on and unlock it or the phone won't expose the cards.

Today i plugged my phone to the usb cable and instead of getting the usual connection option screen... nothing... The phone charges but no Data transfer. Did hard reset, still nothing.. now im stuck with the old firmware... any help plz?
might be the cable that you're using. i used before a cable that is not the original and the same thing happened to me, i.e. pc cannot recognize device.
Try Settings-->Other-->USB To Pc-->UNCHECK (enable faster data sync) this should help...
cable : original came with the phone (used to work up until b4 yesterday) also tried another micro usb cable that came with me N900 but still nothing.
I did the un-check "enable faster sync" still nothing
Did soft reset, hard reset using volume keys, and factory reset from phone setting itself. still nothing.. the phone charges.. but no data transfer.. its something to do with the phone because i tried multiple PC's the phone doesn't bring up the connection type option page

No harm in checking.Infact i faced similar issue once and the USB2 was disabled.It took me an entire week to diagnose the problem.These PCs have got a mind of their own and do mischievous things on their own without our knowledge.
But since its not working on multiple PCs,i am not sure.We'll hav 2 wait 4 a solution i guess...
hmmmm.. would a full system format and re-install be possible? and would it fix it? (talking bout on the phone)
HELP, HELP
SAME PROBLEM WITH HTC2 T0MOBILE
even on the boot loader screen, it charges but no USB stuck on serial.
even when on sleep mode and plug the cable orange led is on but it didn't wake up for choose (active syn or stoeag memory)
PLEASE HELP
i can do nothing, HSPL or rom upgrade
the cable and the USB drivers are tested more than 100 times
Most horror problems I had with the USB sync have been down to not having the latest version fo Activesync from microsoft. Uninstall the old version thwen reboot - now download the 4.5 version which I think is the newest and last version they made (unless im out of date) and then reboot the machine, then connect up the phone - but not immediately after the machine has booted wait a couple on mins, Windows takes longer than it often appears to be ready to go. One your hard drive led flashing light has settled down it is probably time to try. Then see if it finds all the devices in your phone.
If it doesnt go into the control panel and double click system, hardware tab, then select device manager and see if there are any devices with a yellow sign with a "!" in them. If there are delete them and then unplug the phone and plug it back in again. It might get past some stuck things. If it doesnt see anything new on device manager theres a menu at the top and look for "scan for hardware changes" this gives teh device manager another look at what its got connected.
If that fails open up the USB section under in device manager - its got a little plus next to it, press that plus and it open up all the names of chips you have for your USB control on the pc's motherboard. Write down the numbers and go and get the correct up to date drivers for that type of USB and install them. Then try the process again. Sometimes deleting the USB drivers and just doing a "scan for hardware changes" again, will reset the USB drivers and start things working, however it can get tricky if your using USB mouse and Keyboard to select anything if you delete the USB, because thats what the KM/mouse relies on to control teh machine, so have a PS2 mouse plugged in if you can. If that fails I would suggest reinstalling windows as its probably knackered. It amazing how things start to work wonderfully on a fresh copy of windows.
I have been where you are! And tried every suggestion that was given here. It all came down to the cord. I actually went through 3 different cords before I found one that worked and found that by accident. I bought an external drive and that cord works. For whatever reason, that is the only cord that now works for me. I only use it for data transfers. i use the other cords for charging.
I read this post here:

I wasn't able to get it to work. Phone shows as connected to usb in the top bar when cable is unplugged. Phone shows spinning battery icon and refuses to boot unless usb is connected. Anyone else has this issue? Any ideas? Not sure where to go from here anymore.
Currently running Fusion.
I have the same problem, No USB connection to PC. also.
A new Vibrant is comming to replace the actual one, I try almost everything wi=htout sucess, I can't ODIN or ADB.
I had to get a new phone sent. It kept saying, connected. Disconnected. Connected. Disconnected.

Rub a pin on the USB port on your phone. And try blowing on it.
I had the same problem. Reset my phone, called customer service, etc. I now have a new phone coming but I think I found the problem. Open adfree and revert, then uninstall. Fixed my problem. I then went back to my dropbox and found an old version and I'm running that just fine now.

Are you getting "usb device not recognized" from your computer?
You've installed the samsung drivers?
Was it working at a given point in time and now it doesn't work all of a sudden?
I had a similar issue this week where i got "usb device not recognized" from my computer everytime i plugged in the device. I thought i had not installed the samsung mobile drivers properly, or my usb drivers on my PC was messed up, etc etc.
It turned out that my USB charging cable was the issue. It charged my phone fine but did not let me connect it to Odin or even transfer files.
So my suggestion is to try to find someone else's cable and give it a shot.
I used an AT&T captivate cable from a coworker and that's how i found out it was my cable.

from desktop, windows button, in search box just above button type device manager, should be at the top of the windows pop up, clock that, go down to usb controllers, click the plus sign box. the rest was explained above.
USB fix
So I had the same problem. A new oem cable solved it. don't fight too long with this problem just get a new cable.
I have a really weird problem. My computer won't recognize my SGS2 is connected to the computer at all. Meaning no notification sound, no device change in device manager, nor any prompt to install a new driver. I've tried in both MTP and Mass Storage. What's even weirder is that it detects the phone in Odin mode and even installs the correct drivers. I've tried just about everything I could think of, such as the following:
-Cleaning the microUSB port with alcohol & new tooth brush
-lifting the microUSB connector slightly
-Using a toothpick to try to pick out any residue in mUSB port.
-Connecting while TWLaucher is set as default
-Using Wireless & Network setting > USB utilities.
-Taking out the sim card and external microSD card and booting & rebooting it.
-Restoring the stock Firmware
-Different wires, including an untouched mUSB wire that came with the phone.
-Different computer that doesn't have Kies or the said drivers installed. (Still didn't make a notification sound or bring up the "new device" prompt)
I just want to make sure I tried everything possible before sending it in for repairs.
EDIT: Oh forgot to mention that I had other problems before getting to this one. About a week ago Car mode would always activate by itself constantly. Even during use. Also the phone would refuse to stay turned off. After booting down, the phone would turn off. However, after some random amount of time, the phone would turn on by itself. During that time, connecting the USB wouldn't keep charging the phone. The phone would go between connected and disconnected randomly. Sometime off and on multiple times with in seconds. Other times would charge for hours and randomly stop charging. I've gotten the phone to charge whenever its connected now by cleaning the port, but the computer still can't recognize it as a device. Also the screen will randomly turn on, plugged in or not, and I have to manually turn it off again. However, if I turn it off right away it seems to lock up. So I have to unlock the phone the press the power button again to lock and turn off the screen. Don't know if this information helps.

Try another usb port, sometimes that helps or reinstall the usb drivers in Kies
Ignore, hadn't read all he'd tried.
Bump: Additional information.
Same problem here
I have exactly the same problem!!
My thought is that the USB connector get wet and stopped working properly. As fas as i know, USB connector is composed by 3 cables, one for charging, one for data transfer and another one to detect Car Dock.
It seems that Odin is using Car Dock cable (?¿?¿) instead of Data, so you can use Odin and not Data.
Also that would explain why car mode just kicks in by itself (short circuit between car cable and probably power cable).
I will also sent it to a SAT, since i tried everything via software....
I have the same problem. Try plugging into a mates laptop, see if it works on their one.

Hi there.
I recently rooted my X2 using the Moon Shadow's "zergrush" method. Everything works great, except I find myself unable to change the USB settings. The last state it was in was Charge Only, and Debugging is enabled. When I plug my phone into my laptop, it does charge, but the notification doesn't show up on the drop down bar. When it's plugged in all I get is the "USB device not recognized" error. I've googled around and tried many options I've seen (resetting phone/laptop, trying a new cable, reinstalling drivers) but nothing seems to work. I was hoping that someone would know of a hard way to change these settings, thanks!
I had a similar issue recently. If you are using Windows, Google search for "USB reset". Microsoft has a "fix-it" tool that will reset the USB host controllers. After that, remove and reinstall your device drivers. Reboot both your computer and your device. Then try connecting the USB again.
