The PowerA gamepad initialization quirk worked with the PowerA
wired gamepad I had around (0x24c6:0x543a), but a user reported [0]
that it didn't work for him, even though our gamepads shared the
same vendor and product IDs.
When I initially implemented the PowerA quirk, I wanted to avoid
actually triggering the rumble action during init. My tests showed
that my gamepad would work correctly even if it received a rumble
of 0 intensity, so that's what I went with.
Unfortunately, this apparently isn't true for all models (perhaps
a firmware difference?). This non-working gamepad seems to require
the real magic rumble packet that the Microsoft driver sends, which
actually vibrates the gamepad. To counteract this effect, I still
send the old zero-rumble PowerA quirk packet which cancels the
rumble effect before the motors can spin up enough to vibrate.

XBCD [0][1] is an OpenSource driver for Xbox controllers on Windows.
Later it also started supporting Xbox360 controllers (presumably before
the official Windows driver was released).
It contains a couple device IDs unknown to the Linux driver, so I extracted
those from xbcd.inf and added them to our list.
It has a special type for Wheels and I have the feeling they might need
some extra handling. They all have 'Wheel' in their name, so that
information is available for future improvements.

360Controller [0] is an OpenSource driver for Xbox/Xbox360/XboxOne
controllers on macOS.
It contains a couple device IDs unknown to the Linux driver, so I wrote a
small Python script [1] to extract them and feed them into my previous
script [2] to compare them with the IDs known to Linux.
For most devices, this information is not really needed as xpad is able to
automatically detect the type of an unknown Xbox Controller at run-time.
I've therefore stripped all the generic/vague entries.
I've excluded the Logitech G920, it's handled by a HID driver already.
I've also excluded the Scene It! Big Button IR, it's handled by an
out-of-tree driver. [3]

Add USB IDs for two more Xbox 360 controllers.
I found them in the pull requests for the xboxdrv userspace driver, which
seems abandoned.
Thanks to psychogony and mkaito for reporting the IDs there!

There are several quirky Xbox One pads that depend on initialization
packets that the Microsoft pads don't require. To deal with these,
I've added a mechanism for issuing device-specific initialization
packets using a VID/PID-based quirks list.
For the initial set of init quirks, I have added quirk handling from
Valve's Steam Link xpad driver[0] and the 360Controller project[1] for
macOS to enable some new pads to work properly.
This should enable full functionality on the following quirky pads:
0x0e6f:0x0165 - Titanfall 2 gamepad (previously fully non-functional)
0x0f0d:0x0067 - Hori Horipad (analog sticks previously non-functional)
0x24c6:0x541a - PowerA Xbox One pad (previously fully non-functional)
0x24c6:0x542a - PowerA Xbox One pad (previously fully non-functional)
0x24c6:0x543a - PowerA Xbox One pad (previously fully non-functional)
