Please ignore messages about Bus 02, it is not a bus linked to USB ports. USB ports are linked to bus 01.
I did the same procedure (plug USRP / USB 3.0 stick and check lsusb) with a computer that is currently OK with USRP b210 over 3.0 (UHD 3.10) : Both USRP and USB stick are "5000M", whereas it is "480M" when using the erroneous computer. This is thus in my opinion excluding a problem of UHD.
