== DETAILS
I've created the concept of a hid_driver_instance_t which is basically
a central place to store the hid pad driver, hid subsystem driver,
the pad list, and the instance data for the above in a central location.
The HID pad device drivers can use it to perform HID operations in a
generic manner.
This is more-or-less a pause point so I can catch up with upstream.
== TESTING
Haven't tested this yet. Compiles without warnings though!
== DETAILS
The handshake stuff is derived from the old HID2VPAD, just in knowing
what data goes in what report.
- Added the HID_REPORT_ flags to syshid.h
- Renamed the generic "REPORT_TYPE" flags to be meaningful
- also fixed incorrect parameter list for set_protocol
== TESTING
The functions aren't implemented in wiiu_hid.c just yet,
so this is gonna crash if you try to run it.
== DETAILS
The current HID implementation assumes a very low-level USB library
is being used. This causes a problem on Wii U, because the Cafe OS
only exposes a high-level interface.
To get these functions exposed to the HID pad drivers, I had to make
three changes:
1. I added the legacy "send_control" function to the HID driver
interface
2. I modified the signature of pad_connection_pad_init() to send the
driver pointer instead of the function pointer
3. I updated the HID pad drivers to keep the pointer to the driver
instead of the function pointer, and updated the calls into the
send_control function as appropriate
4. I updated the HID drivers to use the new pad init signature
== TESTING
Untested, in theory it should work without a hitch because at this
point all I've done is abstract things a little. I still need to
update the HID pad drivers to use the Wii U-specific calls as
appropriate.
In order to have a controller working you need:
1) Have a matching HID autoconfig file in autoconfig/hid for your controller.
2) Create a "connect" driver for the pad in "input/connect" folder (source code of RA).
3) Once you are in RA, change the joystick driver to HID and restart.
4) You may be now able to use you USB HID compatible pad in RA.
I included some "connect" drivers as an example. It also need to include them for compilation.
