Unfortunately, it's not possible to disable the quirks at runtime (without recompiling). There are static and runtime applied quirks, you can only change the runtime quirks; the static ones are always applied.
You can look at drivers/hid/usbhid/hid-quirks.c (line 1203) in the kernel source. When idVendor = USB_VENDOR_ID_MICROSOFT (0x045e) and idProduct = USB_DEVICE_ID_DESKTOP_RECV_1028 (0x00f9) the quirk is applied (and it breaks my multimedia keys). -- [intrepid] REGRESSION: multimedia keys no longer working https://bugs.launchpad.net/bugs/281993 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
