Unable to Connect with Debug Probe Through Remote USB Hub

[yalkhayyatmke]

I was running pyOCD on a virtual machine, with the debug probe connected to a port on a AnywhereUSB remote USB hub. The probe itself is detected correctly-It's a ST-LINK V3. When opening a session with ConnectHelper, the code eventually steps into flush_rx in pyocd\probe\stlink\usb.py. This is the fix I implemented in order to get it working:

Normally, it would get stuck in this while loop forever, never hitting an exception. I also noticed, the rx_buffer was normally an empty list, but in my case it was a list full of 0's. So, to exit the loop, I added a check to see if the rx_buffer only contained 0's.

To clarify, the device and probe connections were all fine. I was able to connect and flash with STMCubeProgrammer for example.

Let me know if you would like any more information.
