Am running latest Monterey 12.6.3 on 2021 MBP Max and have an Eizo display, which has 4 USB ports and a RJ45 LAN port (what Eizo calls a 'docking function'), connected to my MBP via USB C. The LAN works (running a simple switcher for an internal network). The 4 USB A ports on the Eizo, however, do not show any signs of life. I tried the Terminal command suggested above (sudo killall -STOP -c usbd), to no avail, and Eizo actually referred me to this thread - seems they are as exasperated as the rest of us? In any case, I do hope that Apple will assign this high priority and sort it out without delay. Please. Thanks.
