I connected the ASUS DVD Drive (SDRW-08U9M-U) with an other cable with 2 USB-A connecters to a not powered USB HUB wich is connected via USB-C cable to the M1 Macbook air.
The DVD Drive was not recognised with the original ASUS cable with the USB-C connector.
Try a more direct connection to the Mac ie no hub
USB-C to USB Adapter - Apple
If in doubt I would contact ASUS for Support/Help/FAQ/known issues/ compatiblity
