# Force feedback support for MOZA steering wheels # Universal Force Feedback driver for Linux
Linux module driver for MOZA driving wheels. Linux PIDFF driver with useful patches for initialization of FFB devices. Primarily targeting Direct Drive wheelbases.
MOZA wheels are basically DirectInput wheels. ## What's different between this and native pidff driver?
In that repository - copy of pidff driver from 6.6 kernel with some changes around infinite length effects (like that https://github.com/berarma/ffbtools/issues/26) That driver allows most DirectDrive wheelbases to initialize and work.
Most of the DirectDrive wheelbases are basically DirectInput wheels, but with some caveats, which Windows allows, but pidff doesn't.
In that repository - pidff driver with some changes, which allows most of the DirectDrive wheelbases to work.
1. Added quirks for better initialization rules for different wheelbases (MOZA, VRS, Cammus)
2. Fixes for infinite-length effects
3. Fixes for out-of-bounds values (no more spam in kernel logs)
And that's basically it And that's basically it

### MOZA
**[Boxflat](https://github.com/Lawstorant/boxflat)** is a Linux Pit House alternative made by [@Lawstorant](https://github.com/Lawstorant)
For now, please, use [Android App](https://play.google.com/store/apps/details?id=com.gudsen.mozapithouse) **[Android App](https://play.google.com/store/apps/details?id=com.gudsen.mozapithouse)**
### Non working method
You can try to setup MOZA PitHouse with Wine. You need to tweak Wine prefix for them.
That soft uses hidraw to set up a base. You need to create `udev` rule for allow access to hidraw device:
```
echo 'KERNEL=="hidraw*", ATTRS{idVendor}=="346e", MODE="0660", TAG+="uaccess"' | sudo tee /etc/udev/rules.d/11-moza.rules
udevadm control --reload-rules && udevadm trigger
```
Then you need to force MOZA soft to use hidraw, not SDL, to find devices:
1. Create new Wine prefix for them:
`mkdir ~/moza-wine`
2. Launch regedit in prefix:
`WINEPREFIX=$HOME/moza-wine wine regedit`
3. Create two keys in
`HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\winebus`:
* `DisableInput` (DWORD) - set to `1`;
* `Enable SDL` (DWORD) - set to `0`; (yes, variable name contains space)
4. Now you can launch soft through that WINEPREFIX:
`WINEPREFIX=$HOME/moza-wine wine MOZA\ Pit\ House.exe` - launch your PitHouse from installation directory.

1. Firmware update does not work. Please use Windows machine or Windows VM for any firmware updates - Buttons above 80 simply don't show up. This is a Linux limitation and we're trying to fix that in the upstream
