Thanks for that.

Great.

OK.

Fixed the typo for now. I don't have enough bandwidth to actually think
about the license acceptance part. Might be worth filing separately
against hw-detect for later consideration.

Definitely a typo/thinko, fixed.

Please share the contents of that device's directory, so that the lookup
can be adjusted. I could only test with one single device, so I haven't
tried to be clever and think about all possible cases. Feel free to
spawn a specific hw-detect bug report for that.
