Last update :
When I plug a USB 3.0 stick, dmesg still says that it acts with
"full-speed", however lsusb gives me :
Device can operate at SuperSpeed (5Gbps)
This does not appear when USRP is plugged in instead of the USB stick.
Also I noticed in the very early messages of dmesg :
[ 1.684307] xhci_hcd 0000:00:14.0: Host supports USB 3.1 Enhanced
SuperSpeed
Regards,
Rodolphe
