The main goal of this utility is to provide workaround for steam-for-linux issue which makes Valve's Steam Controller unusable in BLE mode with bluez 5.56 or newer installed. It can also be used to look at the data send from and to SC.
This utility catches newly connected SC and creates Virtual SC that acts as a bridge between steam and SC. It unfortunately relies on using sudo as you not only have to access /dev/uhid but also access SCs that should not be readable by normal user so that steam also won't be able to read them.
Before starting this utility you have to make sure that real SC connected via BLE won't be readable by steam. The best way of doing this is by creating udev rules. First of all, exclude SC via BLE by adding ATTRS{idProduct}!="1106" to all rules matching SC via BLE. You might find them in files called 60-steam-input.rules, 71-valve-controllers.rules or other with similar names in /usr/lib/udev/rules.d/. Your rule in steam-input.rules before changing should look like this:
# Valve HID devices over bluetooth hidraw
KERNEL=="hidraw*", KERNELS=="*28DE:*", MODE="0660", TAG+="uaccess"
after the change it will look like this:
# Valve HID devices over bluetooth hidraw
KERNEL=="hidraw*", KERNELS=="*28DE:*", ATTRS{idProduct}!="1106", MODE="0660", TAG+="uaccess"
Now, create new rules file e.g. 69-sc-ble-bridge.rules with the following rules:
KERNEL=="hidraw*", KERNELS=="*28DE:1106*", ATTRS{country}=="00", MODE="0600"
KERNEL=="hidraw*", KERNELS=="*28DE:1106*", ATTRS{country}=="01", MODE="0660", TAG+="uaccess"
- glib 2.36 or newer - should be already installed, as it is required by bluez.
- Kernel 5.6 or newer
To build this utility run:
make
Executable file should appear in bin directory.
To use this utility run:
sudo ./sc-ble-bridge
Now you should be able to once again use your SC via BLE.
- Better structuring and fix typing
