I just upgraded from the original UR-C driver 2.0.1 to the latest 2.0.3 on Windows 10 1909(18363.719) and USB 3.10(high speed USB) which worked flawless before is now impossible to activate. It defaults to USB 2.0 all the time. Same USB port. USB-drivers are Windows own(which looks to have been updated from Microsoft as of 20200220). Mainboard is Asus Crosshair VII with bios 3004 and using a AMD Ryzen 9 3900X.
It’s not critical for myself at the time as I have several interfaces/computers but it looks like something Steinberg/Yamaha needs to look into. Could be a lot of unhappy customers if USB 3.10 isn’t working anymore with newer software.
