PPC 4100 using v. 3.8 of active sync on a windows xp home computer

I cannot get the device to sync via usb. The active sync on the computer does not know that the ppc is even there. I can however sync other ppcs using the same computer just not the ppc4100.

Has Anyone else had this problem, need to at least connect to copy the unlock file but I cannot so it is totally useless at this point.

Any suggestions?

Thanks

Chris
