Atheros is usually a good choice although not always. There are wifi
bluetooth combo cards that are a bad choice. A portion of the card is reliant
on non-free firmware that won't work in Trisquel.
The documentation I looked at was unclear for this card although it is a
bluetooth/wifi combo that I haven't seen before. Other users have reported
issues with this card in 5.5. It may be fixed in Trisquel 6 with the newer
kernel.
I'm going to investigate it further although it's going to take a while to
determine if its free software friendly or not. The chips are not as readily
available as they could be.
