Raspi 4 failing to make usb connection to MCU

Yeah, looks like you are affected by the Debian bug:

Try following approach

  1. Execute sudo apt edit-sources
  2. In the editor that opens (if asked choose nano) add following lines at the end:
    deb http://ftp.debian.org/debian bullseye-backports main non-free contrib
    
  3. Save and close
  4. Run: sudo apt update
  5. Run: sudo apt install udev -t bullseye-backports
  6. Reboot
  7. Try again
