Hey Aapo, There seems to be a problem in the keymap you provided for inclusion in the kernel. In drivers/media/usb/dvb-usb/m920x.c, 2 keys are triggered by the same keycode: 790 ↦ { 0x08, KEY_SUBTITLE },• 794 ↦ { 0x08, KEY_VIDEO },↦ ↦ /* A/V */• Could you please check what the correct values are for both of those keys? Thanks!
