USB very slow when capturing video

Hi all.

I have the latest Parallels running on a 2012 MacBook Pro (Catalina), with Windows 10 as the guest OS: generally, it's fine, and a performance upgrade on the VirtualBox install I had, except for problems with video capture from a DSLR. I have a Canon DSLR which is connected by a USB cable - I'm only getting FPS of 1-2, versus the 20+ FPS I get under VirtualBox and native Windows. I get the same issue if I try imaging with other image capture software on the Windows install, so it's Parallels/OS related rather than the imaging software.

Paralells says that USB 3.0 is enabled, but the FPS suggests it's down at USB 2? Perhaps I'm missing something silly - any advice gladly welcolmed.

Cheers,
Brian
