Info, Print and Open all seemed to work OK so I tried running a simple RX flow through GRC and I'm getting similar errors there.bladerf-cli -p -v verbose

This is running on a Win10-1803 device that's fairly recent and all USB-c. I do have a C-A converter in the loop but it should just be a physical pass through of USB 3.1 but I'm wondering if the C/thunderbolt controllers are to blame. I'm going to try on an older desktop here in a bit to see if the results are any different but I figured I'd start a thread and see if there were any suggestions.Opening nuand bladeRF with device identifier string: "*:instance=0"
