Problem with parallels?

I just got a macbook and bought parallels and a copy of windowsXP primarily to be able to run my Garmin GPS mapping software.
Everything works fine until I try to plug in my GPS.
Parallels acknowledges the Garmin GPS. But soon after that acknowledgment I get this:

No other app is open when I plug in the GPS. I've tried with the mapsource program both open and closed. I can't get the GPS to come up on the virtual machine!

 

Which Garmin device? For mine, I had to download a new version of driver for windows XP which resolved the issue.

 

I've got a 276C.
I'll search the driver issue thanks.

 

Don't forget to download the Mac version of Garmin web updater. This will insure your 276C is running the latest firmware.

I know I had to do a firmware update on mine (Quest) before I could get it to connect reliably to mac and windows. But in my case, I am lucky enough I have some old XP laptop hanging around for such necessary pains.
