BPv4 Upgrade breaks USB CDC - Windows 11

[htrinkle]

I have upgraded from v6,2 to the latest firmware (built using MPLAB.X, config set for PB v4, no errors).

Programmed using pirate_loader without errors. After update the USB serial port did not come up. Device Manager says Device Can't Start (10). Tried reset and unplug/re-plug USB. No luck. Windows does detect com port and enumerates it (i.e. com5). But port comes up in error state.

Re-programmed with v6.3-r2088 and everything works.

Happy to run further experiments if that would be helpful.

I've encountered this as well. I believe there is a race condition that was introduced in the USB driver changes from v6.3 to the latest firmware.

The USB light is constantly on when connected to a windows 11 machine and windows reports the STATUS_DEVICE_DATA_ERROR.

Spamming the reset button will eventually allow the bus pirate to fully startup and process commands on windows 11 as normal.

I don't have very much time to look into this further, but hopefully this is a good starting point for narrowing down when this bug was introduced to the USB driver on the bus pirate v4.

Maybe #11 is related to this issue.
