Support / adopt for X-65F

[obma]

Hi!
I came across your project during research for my Saitek X-65F (ID 06a3:0b6a Saitek PLC Pro Flight X65 Control System), which is missing an axis (mouse y) with the default driver. So I thought about adopting your kernel module for my device - what would be an absolute first time for me.
Can you give some advice on how to get into this? What tools can I use for testing, how to find out the necesarry bit-operations on the axis, ...?
Or do you even have time and motivation to include the X65F into your project? I could offer testing and provide data ;-)

Regards,
Max

Hi Max,

While I'm not yet sure I want to support the X65F as a part of this project, I'm happy to help with the driver part. For what it's worth though, the kernel module in this project is probably not the right way to write a driver, primarily because of the way it remaps the buttons. That being said, I had made a contribution to the kernel in the past to allow the default driver to send events for the Mouse-Y axis. You can see the changes here.

To start off, we need some information regarding the device itself. You may need to run some of these commands with sudo. Please capture the outputs of the following commands:

• lsusb -d 06a3: -v
• usbhid-dump -d 06a3

We will probably need some additional info on how Linux maps the axes and buttons, but we can leave that for later.

Cheers,
Nirenjan

I've added a kernel module saitek_x65.ko in the x65-driver branch. Could you give it a try and see if it works as expected? If it does, then this should tide you over until we can get the quirks fix into the mainline kernel.

[obma]

Adding the quirks approach works as expected. With your kernel module, the mouse Y works, but mouse X gets mixed up with Hat X & Y. Moving the mouse coolie along x does nothing on mouse x, but changes both hat x & y. Tested on 5.11.6-arch1-1.

I fixed the bit twiddling, it should work now. Can you check with the updated sources? Also, please check the rest of the axes and buttons and see if they work as expected.

[nirenjan]

Oh, and do you want to send the quirks fix to the kernel or would you like me to do it?

[obma]

Your driver works now with all axes and buttons.

Would be nice if you could hand in the quirks fix.

Thanks again, you're awesome!
