USB_EP_CLEAR_HALT(9)	    Kernel Mode Gadget API	  USB_EP_CLEAR_HALT(9)

NAME
       usb_ep_clear_halt - clears endpoint halt, and resets toggle

SYNOPSIS
       int usb_ep_clear_halt(struct usb_ep * ep);

ARGUMENTS
       ep
	   the bulk or interrupt endpoint being reset

DESCRIPTION
       Use this when responding to the standard usb “set interface” request,
       for endpoints that aren´t reconfigured, after clearing any other state
       in the endpoint´s i/o queue.

       Returns zero, or a negative error code. On success, this call clears
       the underlying hardware state reflecting endpoint halt and data toggle.
       Note that some hardware can´t support this request (like pxa2xx_udc),
       and accordingly can´t correctly implement interface altsettings.
