I bought the release version only to use a plantronics usb (dsp 400) headset with Dragon Dictate, (only windows program I need) got the drivers installed, but windows says there is a problem with the device. headset works fine in OS X and bootcamp windows.
The workaround works perfectly with avaya softphone!. I am a happy camper. Hopefully Parallels will get the driver right soon, but for now this is perfect. Thanks for the tip!
I had tried 3 headsets and they did not work and I finally succeeded
Did you made sure that you had it plugged in MacOSX - before opening Parallels and the VM ? Check in MacOS sound preference that iMic is selected for input and output - (mac does not always get it automatically). Adjust the volumes to a confortable level
then open Parallels and Windows. In my case it then worked. You can test it with the Magnetophone or the XP sound control panel
If it doe not solve your problem or if sound quality is a problem, see more details of "unused_user_name" suggestion in another thread. Very useful http://forums.parallels.com/showthread.php?t=2865
