Ur44 not recognized

I use a Ur28m in My studio, and a Ur44 for live gigs,using the same laptop. After installing the new Yamaha driver (1.10.3) the ‘28m works fine, but under the new driver, the ‘44 is not seen in windows 10x64. Anyone else having this problem? If so please let me know before I contact tech support.

I just bought a new iMac and what ever I do it can not find my UR44. I use Cubase 10 and have tried with older versions but no luck. It seem to be an issue between the Mac and UR44.

First, have you Turned on the cc switch on the back of the ur44. It is labeled “cc mode” and is next to the USB port.
