.TH "USB_EP_CLEAR_HALT" "9" "09 April 2004" "" ""

.SH NAME
usb_ep_clear_halt \- clears endpoint halt, and resets toggle
.SH SYNOPSIS
.sp
\fB
.sp
int usb_ep_clear_halt  (struct usb_ep * \fIep\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIep\fB\fR
the bulk or interrupt endpoint being reset
.SH "DESCRIPTION"
.PP
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.
.PP
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.
.SH "ABOUT THIS DOCUMENT"
