OP-1 (v1) & TE ASIO driver

Been a long while since I wanted to hook my OP-1 up as an interface (on Windows) - only just noticed that TE have their own ASIO driver now, most recently updated a couple of days ago too.

I downloaded/installed it, but after selecting the driver (“teenage USB audio device”) the further dropdowns (I/O on Reaper for example) are blank.

Does this driver not work with the original OP-1? I reinstalled TE’s fw 246 (rather than the modified one I had on there) in case that was the issue, but it’s made no difference.
