Both ports are USB 2.0 (backward compatible with USB 1.1).
Not sure why one of the other reviews thinks this card has two external USB1.1 ports as I've bought around 10 of these cards and have had not problems.
Be aware of unusal brand names offering cheaper alternatives, some this these cards have trouble straming data at high speed and lock up.
If you need a USB2.0 card for your PC, look no further than this, Belkin is a name you can reply on (and no I dont work for them)
