I am using G920 steering wheel with 0.6.1 & glib 2.23 both from ./AppImage or debian package on Ubuntu 16.04. I get the error - 'Unsupported model'. How is it? The documentation says that it is supported.
Did you let to pyLinuxWheel install the udev rules for your steering wheel? pyLinuxwheel could show "Unsuported model" message if you don't have the udev rules installed for your wheel or if your kernel is too old to detect and support your model.
pyLinuxWheel install these rules at the begining of the execution but only if you give it permission. Other possibility is execute pyLinuxwheel with sudo.
Check if you have the udev rules properly installed, and check if Linux is detecting you steering wheel (you can use the lsusb command for this).If these two things are ok, but pyLinuxWheel does not work, open an issue in my gitlab page with the output of the pyLinuxWheel and the lsusb command.
On the other hand take in account that Ubuntu 16.04 is an old distribution and therefore with an old kernel. So you can have problems with your steering wheel that with a newer version could be fixed, as you can read for example in articles like this
