My (newest) Canon scanner has a USB Type C (USB-C) plug.
The supplied cable is a USB-C to USB Type A cable.
My laptop only has USB-C.
So I thought, I’ll just use a short USB-A to USB-C adapter:
Seems like it would work.
You can’t go USB-C –> USB-A (adapter) –> USB-C.
The scanner seems to have power and/or timeout issues.
The solution is to either a) use a USB-C –> USB-C cable or b) use a laptop with a USB-A port.
