The answer

Short answer Yes, with a USB-A to USB-B cable from the computer’s USB-A port to the device’s USB-B port. The cable, computer and device must all support the USB speed you need.

Before you buy

What must be true

One direct link, without a hub, dock or bridge
Host and peripheral roles are documented and compatible
Exact cable assembly is documented for these endpoints
Host explicitly supports the requested USB mode
Peripheral explicitly supports the same requested USB mode
Cable explicitly supports the requested USB mode

Watch out

Direction and exact products matter

Connectors that fit do not prove a connection works. Check that the exact cable or adapter is documented for USB-A → USB-B, and that both devices support what you need.
