I can also report I have had this exact same issue with a B200, although I typically run rx_samples_to_file. I've also tried external power to no avail. I've also run the B200 on the haswell Intel NUC which also has the series 8/C210 USB 3.0 controller. I haven't seen this issue yet on the NUC but I don't have a lot of runtime on it yet.
Could you please post your results to the mailing list or can Ettus support contact me offline? I'm very interested in the resolution to this issue.

Hi all -
I've seen this pop up now and again on this list. Basically while running an RX operation (osmocom_fft or uhd_fft) the B210 will sporadically disconnect from the USB 3.0 hub and then it will immediately reconnect. I can see this in dmesg and /var/log/syslog. It was suggested to me that this may be a power brown out issue since I have a TCXO GPSDO module mounted on board, but I observe the same error even while connected to wall power through the standard 6V, 3A power supply. Here is the console output I see.
The receive packet handler caught an exception.
RuntimeError: usb rx6 transfer status: 5
