Keychron VIA app Linux

Keychron VIA app Linux

Open chromium.

Go to https://usevia.app/

You might see the error:

Vid: 0x3434
Pid: 0x0273

Then navigate to:

chrome://device-log

See which device you are trying to write, in my case is:

HIDEvent[13:31:37] Failed to open '/dev/hidraw2': FILE_ERROR_ACCESS_DENIED
HIDEvent[13:31:37] Access denied opening device read-write, trying read-only.

Then allow write access with:

sudo chmod a+rw /dev/hidraw2

Do your changes in your keychron keyboard.

When you finish, remove the permissions with:

sudo chmod 600 /dev/hidraw2
