Not sure if this belongs in UR44 or Cubase forums.
I upgraded some time ago from CB 9.5 to Pro 11 and at that time moved homes, so I packed my DAW all up, and have just now set back up my DAW.
I’ll be darned, but in Studio Setup>Audio System>ASIO Drive pulldown, UR44 is no longer visible. I do have a Behringer UMC204HD that it does recognize, FWIW.
When I turn on the UR44, I get the blinking light.
I would recommend to reinstall the driver. If you are on Windows, install it as administrator, please.
