So the solution as found in two patches linked here: https://lists.opensuse.org/opensuse-arm/2020-09/msg00008.html https://lists.opensuse.org/opensuse-arm/2020-09/msg00024.html

Could you help getting them upstream?

I'll have a look!

@Matthias, did you upstream those 2 patches?

Unfortunately not. Up to now I wasn't able to find a way to implement this on the chip level. On of the patches change the usb keyboard implementation which will break USB on other RPi's. I'll have to have a deeper look. I think now I'll find more time to do so. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=1167675 http://bugzilla.opensuse.org/show_bug.cgi?id=1167675#c22 --- Comment #22 from Stefan Br�ns --- I have just submitted the patch for interrupt out endpoints upstream. This should fix the issue of Linux gadget keyboard being rejected (which does affect any DUT which uses u-boot, not only RPIs). With this accepted, you should be able to use and Rpi3 as KVM (Linux gadget keyboard) and e.g. a Pine64 as DUT (which uses interrupts for transfers) or maybe an Rpi4 (which has as XHCI controller and not the awkward DWC2). @lnussel: For the missing/incomplete support of the SetIdle request by the gadget support, I think you can/have to implement that in userspace. Taking the code from https://www.kernel.org/doc/Documentation/usb/gadget_hid.txt , just add a 500ms timeout to the select() loop and send the last report again. -- You are receiving this mail because: You are on the CC list for the bug.
