“I bought this to use on a Raspberry Pi running openelec. It did install without issue, but crawled along - I suspect needing more power, e.g. using a powered USB hub. (My PSU for the Pi is rated 1 Amp). I have instead used it on a Windows 7 PC (which installed drivers automatically) and runs very well.”
“This USB WiFi Adapter works straight away when plugged into Raspberry Pi (or USB hub). No configuration or fiddling about was needed on both Raspbian and RaspBMC/OpenElec. Very happy with the purchase. Recommended!”
