UR22C in Linux

When the Interface was connected on a USB 2.0 port instead of 3.0, it produced clicking noises every few seconds. The manual says it has to run from USB 3.0 due to the power requirements.

Here is all the other, probably irrelevant, stuff that I tried while it was on the wrong port

maybe that helps you if you get clicking noises even though it’s on usb 3.0
