USB-HID Keyboard) Product: Drivers Version: 2.5 Hardware: All OS: Linux Status: NEW Severity: normal Priority: P3 Component: USB Assignee: drivers_usb@kernel-bugs.kernel.org Reporter: ishitatsuyuki@gmail.com Regression: No Created attachment 305872 --> https://bugzilla.kernel.org/attachment.cgi?id=3D305872&action=3Dedit BPF program to fix the quirk My Mistel MD770 (04d9:0339 Holtek Semiconductor, Inc. USB-HID Keyboard) see= ms to have a descriptor quirk that prevents NKRO from working. A device descriptor, a hid capture of NKRO sequence and proposed BPF program for fix= is attached. It's the exact same error as the Topre quirk [1], but the descriptor and of= fset is different. NKRO works on Windows without extra vendor drivers. I'm not sure if Microso= ft just has a better quirk database, or they have some clever heuristics to de= tect this. Before copy pasting the Topre code and calling it a patch, I would li= ke to ask about what's the best way to fix this.
