Hi, I'm having trouble receiving samples with my B210. I get the following
error when I run either a GNU Radio Companion script or the benchmark utillity:
EnvironmentError: IOError: usb rx6 transfer status: LIBUSB_TRANSFER_OVERFLOW
Does anyone have a way to resolve this? Below is the benchmark output:
sdrl@star00:/usr/local/lib/uhd/examples$ ./benchmark_rate --random --rx_rate
