This wifi card seems to work with other laptops, but when tested on Compaq Presario CQ60-207EO with Trisquel 5.5 it did not work even though it was revision 01.

Revision 01 tested to work with Trisquel 5.5 on Eee PC 4G and MSI EX710.

This wifi card is recognized as an ethernet card by lspci for some reason.
