I bought this via Amazon as it explicitly stated that Linux was supported, but a later query to the supplier revealed that it is Windows only, so no use to me. (Supplier gave me a refund, but didn't want it returned.)
It shows up as a USB device, so I have no reason to suppose that it doesn't work, but obviously I can't tell whether it is actually fully functional.
