It appears that the USB drivers no longer work on Monterey. After installing Monterey the shadow app let me know that there was a problem with the drivers and gave me the option to fix them or uninstall. I tried both options and reinstalled them many times but continued to receive this error.
The USB driver issues on Big Sur took many months after the final release to get fixed so it would be great to get confirmation that this is a known issue and being looked into. I realize that it’s unsupported software, however, that was the argument I heard regarding Big Sur and months of pain could have been avoided that time around by getting in early. After all that’s the point in having Beta access in the first place. ;)
Thanks for your attention on this.
