Support of FFB on new firmware (after v171)

[JacKeTUs]

Driver needs to send proper FFB commands to the wheel with new firmware

At first glance protocol is the same PIDFF protocol, but shifted to the right and with leading 0x01.

Happy to help with testing. Guess I need to get monado configured sooner than I thought!

For testing you need Wireshark + USBMon configured, on both Windows and Linux
Also, please, download WheelCheck.exe (iRacing Wheel Checker tool) (https://www.overtake.gg/downloads/lut-generator-for-ac.9740/)

At first i need some dumps from Windows, with latest firmware available, with simpro2 installed, with Wheelcheck.exe, where you:

0. Start recording of a dump in Wireshark + USBMon
1. Connect the base
2. Launch WheelCheck.exe
3. Set Spring Effect to Simple Spring
4. Change some parameters like Offset X or Coefficient
5. Stop recording

That's one dump. Here is another:

0. Start recording of a dump in Wireshark + USBMon
1. Connect the base
2. Launch WheelCheck.exe
3. Set Damper Effect
4. Change some parameters like Coefficient
5. Stop recording

I have some information from my previous findings, first i want to confirm that protocol after v171 and now (i don't know latest numbers) didn't change

test-1.zip
test2.zip

Hopefully I did that right. Only ever done this on linux before.

[JacKeTUs]

Yep, that's cool

And i can confirm it pretty much the same as my info. Sadly, i didn't save any pcaps when i had the wheel, only some copies of some packets...

Okay, now i want the same tests done in windows in old firmware, v159
You need to follow simagic guides to uninstall simpro2

test-2-firmware159.zip

[Ashtoruin]

test-1-v159.zip
test-2-v159.zip
Removed the Registry entries you told me and ran the tests again

[JacKeTUs]

May be should be enough just copying PID descriptor on new firmware
Please try to compile driver from new commit on branch

Hello, I have an Alpha Mini running firmware v182 and a GTS wheel rim. Let me know if you need any support. It's a bummer that newer versions have such drastic changes.
