1) make sure you have the latest active sync installed

C:\Program Files\Microsoft ActiveSync\drivers
or
c:\windows\system32\drivers....with activesync 3.7 anyways.
2) go to contro panel -> system -> device manager -> view device b
connection -> plug and play bios -> pci bus -> usb host controller -usb root hub
3)delete everything uner usb root hub.
4)from control panel run add new hardware
5)now everything under your computer's usb hub including the cradl
will be installed properly.
6)once this installation is performed, you will make sure to see "H
USB Sync 1620" under USB root hub
