I have a WelchAllyn Digital Macroview Otoscope but it won't connect to my Windows XP under Parallels with error - "Unable to connect the USB device to your virtual machine". My machine is Macbook Pro 10.6.6. I have an iMac running WinXP under bootcamp, and the Digital Otoscope works fine. Please advice. Btw it's listed under the Devices->USB->DMV
