Hauppauge 950 WinTV Tuner

I've been trying to get a 950 working on a Mini PC with openelec 7.

I get :
# lsusb -v | pastebinit
can't get debug descriptor: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable
can't get device qualifier: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable
can't get device qualifier: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable

It works fine on my windows pc.

I have tried it with both and now I am on Libreelec 7.0.2 the with the same issue. Sorry for the confusion.

I hate to be a dummy! Should I use a powered USB?
