Implement the mechanism for optional explicit status stage for the MUSB
driver. This allows a function driver to specify what to reply for the

A usb gadget function driver may or may not want to delay the status
stage of a control OUT request. An instance it might want to is to
asynchronously validate the data of a class-specific request.
A function driver that wants an explicit status stage should set the

Currently, for uvc class-specific control IN and OUT requests, in the

The HW can swap the USB differential-pair (D+/D-) for each port
separately. So the USB signals can be re-aligned with a misplaced
USB connector on the PCB.

Hi Felipe,
I'm using a usb composite gadget (g_serial) and it initially has a

the usb cable, the "suspend" callback is called and the "suspended"
