I've build and installed UHD 3.10.1.1 on a Tegra TX2 (ARM64 platform). The
USB 3.0 is working, but I'm getting errors with the USB 2.0 on a USRP B200.
uhd_find_devices works, but uhd_usrp_probe, and the uhd application
examples give the error below. Note that I've tried running with sudo, and
have followed the instructions "Setup Udev for USB" about the
uhd-usrp.rules file. Any advice?
Thanks, -Mike
