Mac OS X: 10.4.10 Parallels Build 3212 HW: iMac Intel Dual Core with 2GB of Ram Windows Guest OS is XP Pro Parallels is configured with 1GB of Ram The device I'm having problems with is a Garmin iQue 3600. It is a Palm device with GPS. When I attempt to sync the Garmin with Hot Sync Manager, XP error window tells me: The selected port, COM1, is not available at this time. HotSync Manager will open the port when it becomes available. Parallels error window tells me: USB device you are trying to connect to the virtual machine is being used by another application. Close that application or unplug the device and plug it again. Then try to connect the device again. Well, of course I have tried all that. Re-started the Garmin. Checked to see if Parallels would recognize USB flash drives. They work. But I seem to be in a loop with the Garmin. Anybody know the solution?
