I'm running a Windows 10 Home VM on a 2017 13" MBP (Touch Bar, 4 Thunderbolt 3 Ports). I use a few different applications that use a live view from a camera - in one case a Canon DSLR, the other a specialized webcam. Both use USB 2.0, which I connect via an Apple dongle to the Thunderbolt ports. What I am finding is that the live feeds from these cameras are coming in at an extremely slow rate - close to what I would expect over a USB 1.1 connection. I don't know how to measure the throughput directly but the frame rates I'm seeing indicate it's about 16 Mbit/sec. Using the same cameras and software with two different cables and a Windows mini PC, rates are 25-30 times faster at least, and I also tested the Canon with its Mac utility and the live frame rate was normal. This definitely isolates the issue to my Parallels Windows VM. Are there any known issues with USB throughput in Windows 10 on Parallels using current Macs? Is there a driver update that might help? I did note that all drivers claim to be current in my Windows VM. I did a forum search but "USB" is too short a term to search for.
