I was trying to build an app using react-native on my arch and while setting up a device, it was not working based on the react-native docs. Based on the doc, a udev rule is added so that the device identified by vendor belongs to the plugdev group.

The problem was that Arch didn’t have the plugdev group. Once this was figured out, the rest was easy. I had to add 3 rules to udev, so that adb could recognize the device and get authorized as well.

SUBSYSTEM=="usb", ATTR{idVendor}=="22b8", MODE="0660", GROUP="adbusers"
SUBSYSTEM=="usb",ATTR{idVendor}=="22b8",ATTR{idProduct}=="2e76",SYMLINK+="android_adb"
SUBSYSTEM=="usb",ATTR{idVendor}=="22b8",ATTR{idProduct}=="2e76",SYMLINK+="android_fastboot"

The idVendor is the same as mentioned on the doc and the idProduct are the last 4 digits.
