NAME

6       usb_ep_clear_halt - clears endpoint halt, and resets toggle
7

SYNOPSIS

9       int usb_ep_clear_halt(struct usb_ep * ep);
10

ARGUMENTS

12       ep
13           the bulk or interrupt endpoint being reset
14

DESCRIPTION

16       Use this when responding to the standard usb “set interface” request,
17       for endpoints that aren't reconfigured, after clearing any other state
18       in the endpoint's i/o queue.
19
20       Returns zero, or a negative error code. On success, this call clears
21       the underlying hardware state reflecting endpoint halt and data toggle.
22       Note that some hardware can't support this request (like pxa2xx_udc),
23       and accordingly can't correctly implement interface altsettings.
