Every time I insert a USB device, it comes up with the message: USB device not recognized . Any solutions? I have absolutely no USB's in my slots. Thus I cannot insert anything in including to sync my mobile phone. I've already tried resetting the SMC which did not work.
Different USB port. There are usually 3 or 4 of them. If you can, format the USB drive (if you have nothing on it or already have copies of what is on it). It will take 10 seconds, but will wipe all data. It should be recognized then.

For the Samsung i760, disable "advanced network functionality" in the "USB to PC" setting by uncheckmarking it. Then Vista and WMDC will detect the i760 properly...

uninstall driver then turn off the PC then unplug the power cord from power socket, short its legs then leave it unconnected for 5min, then reconnect it to power socket and turn on PC and install driver it should work :)

Are you dragging and dropping your files into the RECEIVED folder first? If not, you need to. From there, the phone should open up the files.

Did this suddenly start to occur? Were they working before? If so, it is very simple - shut down computer, remove the battery and unplug any power source, wait a couple of minutes and reassemble and power up. Wala! I read all kinds of complicated instructions, started with the simple, and problem solved.
