Hiya!
Thing to check first is that you don't have PC Suite and Activesync
running at the same time.
In some situations Activesynch will not 'see' anything on the USB port
because the other application is using the port.
If you press 'CTL'+'ALT'+'DEL', select the 'Processes' tab, then scroll
down until you see PCSynch2.exe, if you click on it and then click the
'End Process' button, that will close the PC Synch part of PC Suite,
which is normally what causes the problem.
Let me know how you get on.
Cheers
Glenn
