Thank you for your hard work and time! It is a nice tool. Just a heads up, I also will be running the HID View test as well.

Great job! And fast. I think it will be a badge of honour to add this to your features list. A new bullet point. :-)

We need to add another struct to usb_midi.h (there might be other things I discover as I go through this as well): ```` // Class-Specific AC (Audio Control) Interface Descriptor...

The only other things that I think are missing from usb_midi.h are, (a) adding the definition for USB_MIDI_SUBCLASS_STREAM ```` #define USB_CLASS_MIDI 0x01U /**

Maybe you could copy the result to a local variable and see the reason (the value at *reg): volatile uint16_t *reg = EPR(ep); switch (*reg & (USB_EPTX_STAT | USB_EP_T_FIELD |...

Well, FWIW, I never wrote at that level, I always used usbd_ep_write(). I'm going to hazard a guess that the endpoint isn't ready, try again later... you could implement that...

That's good news!

Hi, SILabs EOL'd one of these parts today: https://www.silabs.com/mcu/8-bit-microcontrollers/efm8-universal-bee/device.efm8ub31f40g-qfn24 Also, the UB2 **is** a C8051F38x part, with different printing on the outside.

Does linux have conio.h?

I'm not an expert in this library, but from what I see it is a minimal framework (for which I am eternally grateful). You may be able to find examples...
