UR44 Installation problem

I recently bought a ur44 and tried to install it on a MacOS Big Sur 11.3.1.
I download the Yamaha Steinberg driver supplied with the installation cd. Then I tried with the latest 3.0.5 driver version I found here, but nothing worked. The UR44 doesn’t show in my audio and midi device and the light power light of the ur44 keep on flashing which means it hasn’t been recognized.
is it a driver problem ?
Has anyone had the same problem ?
Thanks for your help
