# usb\_free\_streams(9)

free bulk endpoint stream IDs.

## NAME

usb\_free\_streams - free bulk endpoint stream IDs.

## SYNOPSIS

**int usb\_free\_streams(struct usb\_interface \*** *interface***, struct usb\_host\_endpoint \*\*** *eps***, unsigned int** *num\_eps***, gfp\_t** *mem\_flags***);**

## ARGUMENTS

*interface*

alternate setting that includes all endpoints.

*eps*

array of endpoints to remove streams from.

*num\_eps*

number of endpoints in the array.

*mem\_flags*

flags hcd should use to allocate memory.

## DESCRIPTION

Reverts a group of bulk endpoints back to not using stream IDs. Can fail if we are given bad arguments, or HCD is broken.

## RETURN
