USB hardware in VM or Linux PVR software

[Stephen Wiebelhaus]

I prefer running Linux, but am stuck with Windoze for certain 
applications, namely a USB TV adapter. It's a Hauppauge WinTV-HVR-950Q. 
I've been using it with GB-PVR software for the past year, and have a 
couple hundred hours of shows recorded with that software, which is for 
Windows.
Are any of the Virtual Machine programs support USB enough for this type 
of application? I know VirtualBox, and VMWare support USB, but I don't 
see online that they have support for less common hardware, mainly USB 
drives.
Are there any Linux based PVR software that would support the Hauppauge 
WinTV-HVR-950Q? Would that program be able to import/view MKV files? 
Actually they are x264 video and mp3 audio inside an MKV container.
The GB-PVR software stores all the program descriptions in a file 
database, which I suppose I could live without that information.

Thanks,
Stephen
