Hello ho community,

 

I have an USRP card using a usb cable version 3. When i connect it to my usb port , the card stack  ( Overflow) because it recognize it as usb version 2.

Even if when i verifyied the drivers file where the usb port is of version 3.0.

I want to know why the usb operate at the usb 2.0 speed. And how to fix this problem.

I did'nt find how to fix it at the BIOS setting.

I have an ubuntu 14.04 OS installed at a partition on my laptop.
