Joystick USB HID device - changing identity

[andrewfstratton]

Firstly it's great to have so much working already...

When I use https://pkg.go.dev/github.com/tinygo-org/tinygo/src/machine/usb/hid/joystick this works fine but has an issue with identification/description, e.g.

• Using https://hardwaretester.com/gamepad, with a Badger2040, this is identified as 'Badger 2040 (Vendor: 2e8a Product: 0003)'
• this has the following effects:
  • The Buttons are shown as B0 to B15
  • N.B. B16 (Home) isn't shown Actually Home is mapped to B6 :)
  • Note: using a button number beyond 15 appears to crash
  • There are 9 Axis shown (I haven't tested these yet...)

Suggestion:

• Could the USB HID Descriptor be changed (by api) to allow XBox 360 (or similar) to be selected?
  • I have tested this with an 8BitDo controller, which identifies itself as 'Xbox 360 Controller (XInput STANDARD GAMEPAD)' - this then shows the capabilities as B0 to B16 (i.e. including Home button) and Axis 0 to 3
  • It seems that the USB HID Descriptor could do this - but I got lost in the detail...

I now no longer think the identity needs to change - I may add a different issue later - I'm still testing the default descriptor and trying to get one working beyond the browser test page I was using...
