If your ASUS ProArt P16 crashes when connecting a CanoScan 9000F Mark II, the issue is likely driver or USB compatibility. First, remove any auto-installed drivers via Device Manager and reboot. Download Canon’s last Windows 10 driver, then install it in compatibility mode (Windows 8/10). Disable USB selective suspend and uncheck power-saving options on USB hubs. Use a powered USB 2.0 hub if your laptop only has USB-C/3.x ports, as the scanner prefers USB 2.0. If Canon’s software still fails, try VueScan, which includes its own drivers and works well with older scanners.
