USB Not Recognized
I can't figure out the exact circumstances, but at times the USB connection between my phone and the PC gets broken, and my phone no longer gets recognized. It seems to be a phone-side problem, because it is only rectified when I reboot the phone, but not the PC.
The last time it happened was after an incoming call disrupted my PDANet connection. When I hung up, the USB icon was gone, and I had to reboot.
Does anyone else have similar experiences or more information?
