Instantly recognized as OpenELEC 5.0.8. Rate sufficient to stream all my rips Br 1: 1 with HD audio (files among 30 and 50GB) even with a stage and two supporting walls between my Pi 2 and my wifi router (I think I still have a little luck and I'm at the limit ...). Note: it is possible to connect only 2.4Ghz. No need to connect it to a powered USB hub to operate. The dongle is a large coat and may slightly overflow into the USB jack located next to the Pi 2, preventing connecting another USB device if it is too big.
