If no dpad allow the option to have external DPAD about xid_wheel_adapter HOT 3 OPEN

Unfortunately it's not possible.
You would need to add and code support for it.

One possibility would be to map one of the wheel's buttons to act like a shift function. When it's pressed, the other buttons would act as the dpad.

The lib support for usb hub is hit and miss. You would need to try. And the current code allows just a single controller connected, would also require some code adjustments.

You can also add external analog stick or push buttons and code it to act as a dpad.

In fact it is possible because in GIMX (I use version 8) you simply can map gas/throttle to the real pedals and the menu buttons to the attached controller. GIMX uses the USB output to the console (via serial adapter) and an extra controller connected to it's USB port.

Also in CronusMax with X-AIM you can do this. It uses the authentication controller to the CronusMax for secondary input.

My wheel does not have any ports available. The only one is the RJ-11 style port for the pedals..

Yes it's possible. I've even suggested some ways to implement it.
