Thanks for the details - I'll have a look shortly.

I see - that would be problematic for me as I quite often have 3-4 of
these things plugged in at the same time. Not knowing which port spits
out the message would make it a lot harder to track. In fact my primary
devel box for this (Lenovo Yoga 13) has an rtl8723au soldered on the
motherboard, so the moment I plug in any other dongle I'll have two.

The alternative would be to add a prefer to the individual messages.
