I also have a hub from the hakshop, I have used it to some degree with previous firmware and no ill effects.
Was going to string it together with the AWUS036H, but havent yet because I am still toying with a sandisk fit 16gb and a kingston datatraveler 16gb
(both individually and without hub on recent firmwares)
Knock on wood, the sandisk has not been bricked as other users have mentioned so far but I am expecting it -hence the kingston.
have you any means to test the power output, with and without the hub, while pineapple cycles?
