Please is this problem (and its solution) also applicable to dwc2 (i.e.
e.g. RPi4)?

different driver, so no.

Yes the driver is different, but I was wondering if such situation can occur in dwc2 too and (if so) whether it is already taken care of. Disconnecting the USB device is a standard operation.

I discovered this problem on dwc3 while using g_audio gadget. see here:

You might want to do a similar test with dwc2?


Thanks a lot. Regards,

Pavel.
