If I were to guess it's 2 things. One, the drivers for this machine were not installed (specifically the motherboard drivers.) Sometimes you encounter an owner that thinks if the device manager is clear, then no drivers are needed.
Next at SP2, it's out of date. Update it the rest of the way.
I have (windos xp sp-II) and using Mobile (Nokia c5-00)
Problem is, If I plugged in a USB device (usually a mass storage device) into a computer it doesnt work, and it is not working with pc suit also.
I had take my phone and cable to my friends pc and i find it is working fine that i come to understand my phone and cable is fine.
after that i thought there is some problem with my pc i had formatted my pc but it had not made any changes.
