I'm getting this error when I launch any Windows guest environment:

The necessary USB devices driver could not be opened. You will not be able to connect USB devices to the virtual machine. Try to reinstall Parallels Desktop

I have tried re-installing Parallels Tools, but it doesn't help.

I'd rather not have to re-install Parallels Desktop...

Using Parallels Desktop for Mac 6:

Build 6.0.12106
(Revision 692267; September 7, 2011)
 
Reinstalling PD is easier than uninstalling and reinstalling the Parallels tools. Why wouldn't you do it? Just make sure to completely shut down the VM before you do.

I have the same issue, I did not reinstall Parallels Tools, I reinstalled PD a couple of times now, what happens is it works OK after the install, but if I shut down the vm & the Mac next time turn on the Mac and run the vm the error message comes back.
MacBook Pro (1,1)
