Hallo Marek,
Hi,
Can you be more specific about those logitech receivers ? I might have one of those devices, and I have DWC3 in i.MX8MP and i.MX8MQ, as well as ZynqMP, so I should be able to try and trigger the problem. Can you share the reproducer test case for this problem ?
I can reproduce the issue with Keychron K1 and Realforce keyboards on the usb-c port of my mac mini 2020 model running u-boot. The two keyboards don't work without Jannes patch. With Jannes patch, they work. Other keyboards like my Thinkpad compact keyboard work with and without the patch.

I can also reproduce it with the logitech unifying receiver on iMX8MP DWC3 controller, likely close to what Russell has (046d:c52b Version 18.16).
The same device does work on iMX8MM ChipIdea USB 2.0 controller.
I wonder if this might be specific to the DWC3 controller (driver?) somehow ?
