Looks good to me. I didn't think of adding the flash programming there because while developing I am never reprogramming it, only do it once at the end (you don't...

That's strange, have never seen that one before unless the port was getting overloaded and the overcurrent protection has tripped. The kernel just reports that that has happened. If your...

This has little to do with the kernel, the kernel just reads the overcurrent flag on the host controller/hub and reports it. That's a flaky hw, IMO. See here: https://livegrep.com/search/linux?q=over-current%20change&fold_case=auto&regex=false&context=true...

I would suggest putting a shunt in series with the Vbus line on the USB connector and hooking up a scope there to check whether or not there is any...

Hmm, i don't know what sort of USB hub the RPi uses but it is possible that it is sensitive to drawing current from the data lines too. Or maybe...

Uff, that's a nasty problem to find! Glad you have managed to resolve it.

Just to be clear - my original report was about the enumeration failing **without a debugger attached**. Merely compiling in "debug mode" (= with optimizations disabled, **not putting the CPU...

That's beside the point - you may want to compile in debug mode (with debugging symbols and optimization disabled) for other reasons, not only to debug USB. The MCU is...

I had the same problem - it is the TMC2130 driver issue. Disable the StealthChop (silent) mode on the Z axis in Marlin and the issue will be gone. My...
