Public bug reported:
Both the FC30 Pro and the SN30 Pro are detected by Ubuntu, and are
usable insofar as all of the buttons and axes they do have are all
present. However, they both present a pair of axes that look like
pedals, but which aren't really on the controller. Instead, these axes
default to -32767 and flip to positive 32767 when some buttons are
pressed -- buttons that are already accounted for by some other input.
Axis 4 flips when I press right on the D-pad or the L2 button (button 8).
Axis 5 flips when I press left on the D-pad or the R2 button (button 9).
The controllers also appear to have 14 buttons, but I can only really press 12.
Buttons 2 and 12 cannot be pressed. I thought these would be the Star and Home
buttons, but pressing those does nothing, and these extra buttons are not
present on the FC30 Pro.
It's sometimes possible to work around this with remapping, but the
inability to press button 8 without flipping axis 5 makes it impossible
to do this in an automated fashion; you have to use something like
xboxdrv on the command line, which requires sudo.
