Unable to open device (HIDException) [SOLVED}

Hey,

built a bluetooth stenography keyboard that uses the HID Protocol. After lots of troubleshooting I'm a bit further along.

I get the Error Message "ERROR: got HIDException: unable to open device".

Was told to ask here, with the hint that its a permission issue and I may have to add myself to a group?

Thank you in advance, appreciate any help <3

SOLVED: just configure udev:
1. sudo mkdir -p /etc/udev/rules.d/
echo 'KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0666", TAG+="uaccess", TAG+="udev-acl"' | sudo tee /etc/udev/rules.d/92-viia.rules
2. sudo udevadm control --reload-rules
3. sudo udevadm trigger
