WUDFHost.exe (User-mode Driver Framework Host) High CPU

Hi all,

I searched a bit and haven't found anyone else with this problem. When I fire up Reaper (32-bit) the WUDFHost.exe process maxes out my CPU. I think it's related to a driver that Reaper must be using, but I don't know how to figure out what is the culprit. When I quite Reaper, the usage drops back down to about 3%.

Has anyone else seen this or know how to figure out what is happening?

Thanks!
