Re: [Discuss-gnuradio] funcube pro +

[Volker Schroer]

If you run linux on your laptop try

lspci -k

and look for USB. Then you can find the controller type.

USB 3 supports higher speed than USB 2 and should offer more bandwidth. 
But on my desktop system the dongle only runs on the USB 2 port not on 
the USB 3 port. The same happens with the funcube pro that requires 
lower bandwidth than the pro +. On my notebook there exists only an USB3 
controller Intel 8 Series/C2200 and it works flawless.
