NAME
usb_ep_clear_halt - clears endpoint halt, and resets toggleSYNOPSIS
- 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 lqset interfacerq 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.
