Hello Cinaed,
During the tests I use a USB 3.0 stick that behaves same as the USRP : with
an other computer, both are well recognized as 3.0, but not in the
erroneous machine. I don't think that neither USB stick, neither USRP USB
cable are faulty.
The output for both USB stickand USRP gives is:
bcdUSB 2.10
Also for both :
Device can operate at SuperSpeed (5Gbps)
USB ports are on bus 1.
However, something strange : when USB stick is plugged in (bus 1) at boot
time, it is often detected in bus 2 as SuperSpeed (so as 3.0), then it is
also detected in bus 1, and finally disconnected from bus 2. I don't touch
it during those 3 steps that span over half a second.
I am completely lost.
Thank you !
Regards,
Rodolphe
