UR22 MKII not working on High Sierra

Hi all,

Just tried to use my UR22 MKII on High Sierra, and the class compliant driver gave me heaps of dropouts and crackles, even on regular system audio level, not even in a DAW.

I installed the Steinberg USB driver, and after a lengthy reboot my interface is not seen by the system anymore at all. Tested it on two Macbooks, just to make sure the USB-hub on the newer model isn’t to blame - same result on both.

Is there any remedy to this, any experimental driver or manual adjustements I can try?

Appreciate any lead.
