Adding Devices
--------------
As of commit 3605bede4 libratbag now uses a hwdb entry to match the device
with the drivers.
Your device may already supported by one of our drivers. If so, you can
enable it by adding the device vendor-id/product-id to the static table. For
example, for a HID++ 1.0 device, edit the driver-hidpp10.c file and add an
entry in the hidpp10drv_table. For the other drivers, look for the
driver-{drivername}.c file and do the same.
enable it by adding the device vendor-id/product-id to the hwdb file in
`hwdb/70-libratbag-mouse.hwdb`. For example, for a HID++ 1.0 device, edit
the 70-libratbag-mouse.hwdb file and add an entry with `RATBAG_DRIVER=hidpp10`.
For the other drivers, look for the id of the driver in driver-{drivername}.c
file and do the same.
Then install libratbag, run:
```
sudo udevadm hwdb --update
sudo udevadm control --reload
```
And unplug/replug your mouse. `RATBAG_DRIVER` should appear in the udev
properties of your device with the value you previously set.
If the device doesn't work, you'll have to start reverse-engineering the
device-specific protocol. Good luck :)
