Buzz Buzzers LEDs not working/detected

[joao-pm-santos96]

Hello all,

Thank you so much for this package, it is very very helpful!

Everything works fine, except for a little detail, the Buzz Controller LEDs: they do not work or are not detected. I can play and use them as expected, but the LED do not light up and they should. I know they are all good because I can test them on my PlayStation2.

Also, when using python3's evdev package, the LED's are not listed in the device capabilities....

Is this a known issue or something specific of my machine (Ubuntu 20.04)? Would a udev rule fix it?

Thank you!

Buzzer is only emulated, not actually passed through as is. In theory it could be detected if HID device is buzzer and just pass on reports to it? or just add another "usb pass-through" device to the plugin (which probably should be added at one point).

Can you please guide me to how that should be done? Then I could test it by myself and, eventually, pull request it...

Dunno of the top of my head, evdev maybe doesn't allow to send data, idk, maybe needs hidraw handle instead, check https://github.com/jackun/USBqemu-wheel/blob/789671d7900d66207cff29189ae2577bd3b79a05/src/usb-pad/evdev/evdev.cpp#L30

vid/pid are USB vendor/product IDs.

~~Probably enough to just send HID reports from TokenOut to HIDRAW?~~

E: actually reports are sent to there so passing it to hidraw might be enough https://github.com/jackun/USBqemu-wheel/blob/849904abce0273ffc692a947703bfa0aef852c84/src/usb-pad/usb-pad.cpp#L238

Oh, actually do it like Logitech FF passthrough probably. So send data from SET_REPORT to s->pad->TokenOut(..) maybe.

Open hidraw handle, set mUseRawFF etc and just skip the FFB related data checks :P
