Dear all, I have been using a USRP B210 on a laptop for months now. For reasons, I switched to another Linux session, and using this session UHD fails to talk to B210 over USB 3.0
dmesg tells me it is using the xhci_hcd driver (which I believe is the driver for USB 3.0), and is also mentioning "new high-speed USB", which leads me to think that USB 3.0 link is well recognized and active: [ 306.133028] usb 1-1: new high-speed USB device number 16 using xhci_hcd [ 306.260349] usb 1-1: New USB device found, idVendor=2500, idProduct=0020 [ 306.260351] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 306.260352] usb 1-1: Product: USRP B200 [ 306.260354] usb 1-1: Manufacturer: Ettus Research LLC [ 306.260355] usb 1-1: SerialNumber: 31B9289 However, when running any uhd command line, it fails using USB 3.0: [INFO] [UHD] linux; GNU C++ version 5.4.0 20160609; Boost_105800; UHD_3.15.0.0-release [INFO] [B200] Detected Device: B210 [INFO] [B200] Operating over USB 2. I have also tried with UHD 3.14.1, no improvement. I remember having a similar issue (maybe the same?) that had been solved with something related to udev, but I sadly didn't take any note of this. Do you have any hint? Thank you. Regards, Rodolphe
