I have a freind that is trying to sync his treo 650 to his office PC (windows XP) through a USB cable. I installed the Palm OS with no problems, but the treo is completly unresponcive and will not sync. Furthermore, XP does not recognise a new device. I tried every USB port on the computer and still no joy. I get no error messages and have tried uninstalling and re-installing the OS several times.

One thing: the treo is not at factory specs and has data on it (so I can not reset it). I don't know if this could be the problem...

Any sugestions would be helpfull at this point.

Thanks in advance.
