Bug: SN30 Pro gamepad B-button not working with PS4 gamepad setup

[madskjeldgaard]

Hi!

Thanks again for your amazing work here. It is incredible!

I just tried the gamepad integration and it is very cool. I've got a 8bitdo Sn30Pro with me here and it works somewhat with the PS4 setup included, but not fully. I suspect there are some mismatches in HID info. It would be awesome if you could support this controller as well. I am not sure what info you need, but I traced out all the buttons and sticks using SuperCollider and included the page, id and usage numbers for each element. Let me know if you need anything else to do this, and if at all you're interested. Thanks again for your amazing work :)

Ordered as Page, ID, Usage

Left stick X: 1, 14, 48 
Left stick Y: 1, 15, 49 
Left stick button: 9, 10, 11

Right stick X: 1, 16, 50
Right stick Y: 1, 17, 53
Right stick button: 9, 11, 12

Select: 9, 8, 9
Start: 9, 9, 10

L1: 9, 4, 5
L2: 1, 19, 51

R1: 9, 5, 6
R2: 1, 20, 52

Home button: 9, 12, 13

And here is the HID info for the sn30pro gamepad retrieved via SC:

Usage name and page:    GamePad,    GenericDesktop
    Vendor name:    
    Product name:   Wireless Controller
    Vendor and product ID:  1356, 1476
    Path:   Bluetooth_054c_05c4_4a4ab5d8
    Serial Number:  E4:17:D8:B5:4A:4A
    Releasenumber and interfaceNumber:  256, -1

In case it's any use :)

Actually, on further testing, everything seems to work fine with the PS4 setup, except for the B button on the Sn30pro, this has no effect with the PS4 setup.

I use the Jamepad library for this: https://github.com/libgdx/Jamepad And they use the following gamepad database: https://github.com/gabomdq/SDL_GameControllerDB I guess the database might be the right place to report this.
