When I tried to edit keys using via like I did in Windows, an error occurred.
NotAllowedError: Failed to open the device.
Device: Keychron Keychron Q11
Vid: 0x3434
Pid: 0x01E0
So I solved it like this:
$ sudo vi /etc/udev/rules.d/99-vial.rules
I entered it like this:
# Keychron Q11
KERNEL=="hidraw*", KERNELS=="*3434:01E0*", MODE="0660", TAG+="uaccess"
KERNEL=="hidraw*", ATTRS{idVendor}=="3434", ATTRS{idProduct}=="01e0", MODE="0660", TAG+="uaccess"
And I also did chown ubuntu:ubuntu && chmod 660, but it may not be necessary.
Apply
$ sudo udevadm control --reload-rules
$ sudo udevadm trigger
Try, Again. Good !
