Summary: I followed the directions and I get "Windows has stopped this device because it has reported problems. (Code 43)" On a clean machine probably works great. So read some reviews for other devices. This dongle isn't stable ..
Summary: It works, but the software is bad, which isn't uncommon for ASUS software and drivers really. This actually caused a monitor on a XP machine to toggle on and off a few times when waking from sleep/suspend. Another system I put it on had all sorts of problems as well until I removed it. Yes, it's on sale for $6 or whatever, but keep shopping around. P.S. Dear Asus....improve.
