Michael, thank you for the response. I’ve discovered the issue and it is the USB-C adapter I was using for the USB connection to the USRP B210. The MacBook Pro 2018 provides 4 USB-C ports, so adapters are generally required. I was using the following:

Even though it uses 2 USB-C ports to provide power and connectivity, for some reason the adapter would occasionally force an I/O error on the USB interface. I am now using the following Apple adapter, which has worked flawlessly:
