Thanks for the information. >From the rdesc, the raw report data (01 00 00) does not match may valid HID_USAGE_PAGE/HID_USAGE. That's why they are not processed.
>From the raw data by the command cat /dev/usb/hiddev0 | hexdump -v -e '/1 "%02X\n"', it seems that the data is MicroSoft specific usage page and the usage is 0xDC for mute key and 0xDB for Fn+F10. Can you give me the raw data in parallel (cat /dev/usb/hidddev0 and the /sys/kernel/debug/hid/0003:17ef:60a9.0003/events)? I want to identify the code for HID_USAGE_PAGE/HID_USAGE when Fn+F4 and Fn+F10. When that's confirmed, I'll send you a customized kernel for verification and trying to fix it in our release. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1927545 Title: Some of Lenovo Lenovo Essential Wireless Keyboard Fn keys doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1927545/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
