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. https://www.keychron.com/products/keychron-k1-wireless-mechanical-keyboard https://www.realforcekeyboards.com https://www.lenovo.com/de/de/accessories-and-monitors/keyboards-and-mice/keyboards/KEYBOARD-German/p/0B47202 Cheers, Thomas
