Heyho
I bought a Mad Catz Fightstick TE2 for Xbox One because I wanted to play
some fighting games on Linux. I chose this stick because it has gotten good
reviews and I assumed that the Kernel driver should work because there are
already drivers for Xbox One controllers in drivers/input/joystick/xpad.c.
It turns out that the driver does not work and dmesg just shows
[12293.077720] usb 1-1.2.1: new full-speed USB device number 9 using ehci-pci
when plugging it in. Simply adding the line
{ 0x0738, 0x4a01, "Mad Catz FightStick TE 2", 0, XTYPE_XBOXONE },
(where the two Hex values are VENDOR_ID and PRODUCT_ID) to xpad_device[]
in xpad.c does not help either (which I naively hoped it would).
I realized that the stick does not conform to the USB HID interface
after looking more closely at the lsusb -v output (pasted below).

The Fightstick seems to use a "Vendor Specific Class" and not the HID
interface.
The device is relatively simple having only about 10 buttons and a digital
stick and the Xbox One driver for Windows works for it so xpad.c should
be able to deal with it I assume. Worst case I would have to reverse-
engineer the USB protocol it uses on my Window installation though I
hope that will not be necessary given that the much more sophisticated
Xbox One controller works on Linux already.
What I would like to know is if it is possible to use the xpad.c
infrastructure in this case and maybe some pointers on where to go from
here (I have looked at [0],[1] and [2] but want to check if somebody
has dealt with a similar case already and can give me a hint). Thanks!
Cheers,
Silvan
