Hello, maybe this is not exactly a gentoo problem. Please point me to correct location if i am wrong here.
I've got a MCE-like ir remote together with a USB receiver. Looks like it is detected by the kernel and a input device was created. Most of the keys are working. But - for example - the color buttons do not generate any output. "ir-keytable" (version 1.10.1) returns: Couldn't find any node at /sys/class/rc/rc*. "ir-keytable -d /dev/input/eventxx" gives as output: Name: PHILIPS MCE USB IR Receiver- Spi Using for test ir-keytable -d /dev/input/eventxx -r i got: ------------------- cut -------------------- scancode 0x700e0 = KEY_LEFTCTRL (0x1d) ... Enabled protocols: other lirc rc-5 jvc sony nec sanyo mce-kbd rc-6 sharp xmp ------------------- cut -------------------- But there is no definition of the color buttons in the list above. Tests were done using this command: ir-keytable -d /dev/input/eventxx -t Any hints ? Is it possibe to see the scancodes received by the USB-receiver to validate that the remote really sends data for the color buttons. What kernel options i have to enable ? (Also for checking and not barking at the wrong tree due to hardware problems) Some info about my system: Kernel 4.9.6 (amd64) custom configured Distribution: Gentoo lsmod output: ----------------------- cut -------------------------- Module Size Used by rc_rc6_mce 1580 0mceusb 10365 0rc_core 16719 2 mceusb,rc_rc6_mceusb_storage 48619 0hid_generic 1385 0usbhid 35380 0input_leds 3022 0led_class 3975 1 input_leds ohci_pci 3272 0 snd_hda_codec_generic 52071 2r8169 67900 0xhci_pci 4958 0xhci_hcd 101734 1 xhci_pcimii 4099 1 r8169ohci_hcd 27022 1 ohci_pciehci_pci 4103 0ehci_hcd 41036 1 ehci_pciusbcore 165285 9 mceusb,usbhid,usb_storage,ehci_hcd,ohci_pci,xhci_pci,ohci_hcd,xhci_hcd,e hci_pciusb_common 2222 1 usbcoresnd_hda_intel 18065 0snd_hda_codec 73835 2 snd_hda_intel,snd_hda_codec_genericsnd_hwdep 5866 1 snd_hda_codecsnd_hda_core 40055 3 snd_hda_intel,snd_hda_codec,snd_hda_codec_genericsnd_pcm 78737 3 snd_hda_intel,snd_hda_codec,snd_hda_coresnd_timer 19336 1 snd_pcmsnd 55051 6 snd_hda_intel,snd_hwdep,snd_hda_codec,snd_timer,snd_hda_codec_gener ic,snd_pcmsoundcore 5231 1 snd ----------------------- cut -------------------------- The remote looks like this one: https://www.mythtv.org/wiki/File:Philips-remote.jpg but its branded as olidata.
