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.
