We had the same problem but it was HP printer. After we installed the software this error kept coming up.It turned out that in our case it was the USB cable that we were using..so check that first...use another cable...we did and the problem went away...

Means that the device you are trying is unsupported by your PC.Can you give more error info?

load the driver for the unsupported device if the device has the CD or download the required driver from the net

there might be a problem on your USB cable, a little rust could make some problems to your connections, try replacing it or have your technician check your cellphone

The GPX ML638B takes only AMV files for video. you have to use the utilities tool that comes with it to convert video files. or find one online if you prefer. also you can download pre exsisting AMV format movies to load into it.
just be sure its in a USB mode and load directly onto the 1st area when you open its designated drive location. as for Mp3's no conversion is needed. simply load em onto the device. remember. video and pictures requre it to be set in USB mode (mode button on its side) and music out of USB mode.
while plugged into the PC on its screen will show USb on lower left of screen when its in usb mode. and wont show if its out of it.

The user has not described the operating system in use.
However this problem generally occurs due to incompartible hardware. in this case it is ever stated. ie. Network interface Device. I suggest you disconnect the Network devices including cables, then try to reboot.
If not descibe how far the booting process gets and type of network hardware connected and operating system to your system
