UR22 mkii Output Input

Hey there,
My interface is working good until today inputs and outputs don’t show up. First time i encounter
this. and the white light are sometime blinking, Please help

Hi
If the white light is blinking, you need to check your connection. It could be just a plug that’s not totally inserted, or a power scheme setting, or maybe something else. But first, check the usb cables, then maybe try another usb port and then another cable.
Does the UR22 show up in windows?
