If you touched the key and the LED is off, you are likely missing udev rules for LPC 55 mode.
Either run `sudo solo2 update`, or install <https://github.com/solokeys/solo2-cli/blob/main/70-solo2.rules>
Specifically, you need this line:
SUBSYSTEM=="hidraw", ATTRS{idVendor}=="1209", ATTRS{idProduct}=="b000", TAG+="uaccess

Error: User prompt to confirm maintenance timed out (or udev rules for LPC 55 mode missing)!

@maxwase Thanks for the PR and good luck, the repo is already dead in my opinion. Maintainers are giving a f*ck here. ^^"
