1. Create a udev rule. For example:
   • /etc/udev/rules.d/90-keychron.rules
2. Content: KERNEL=="hidraw*", ATTRS{idVendor}=="3434", ATTRS{idProduct}=="02a1", MODE="600"
3. Change "mode" to 666
4. Enable changes udevadm trigger --type=devices --sysname-match=hidraw[0-9]
5. Connect to keychron and configure as needed
6. Change "mode" back to 600
7. Enable changes udevadm trigger --type=devices --sysname-match=hidraw[0-9]
