USRP B201 board enumerating always as USB 2.0 device

Hi, 

I am trying to use Ettus USRP B201 board for as a radio in Openairinterface 5G codebase. I am facing a very strange issue.

B201 board always enumerates as USB 2.0 device even though I am using a USB 3.0 port in my AMD machine. 

 

I tried doing same in both Windows 10 home edition as well as in Ubuntu 22.04.2 OS.

Both the places, exactly same behaviour and I used latest drivers from Ettus website.

 

Device descriptor sent by B201 device as part of enumeration always shows USB 2.10 as protocol supported.

 

I suspected USB port in my machine and I connected a latest SSD M.2 external hard disk and that device immediately enumerated as USB 3.0 device. That shows that  USB port in machine is for sure Super speed USB 3.0 port.

I even tried changing the cable too but no difference in behaviour.

 

Any definite pointers to help resolve will be highly appreciated.

 

Thanks

Regards

Nitin
