Set up a URB for a bulk data transfer

Synopsis:

#include <sys/usbdi.h>

int usbd_setup_bulk( struct usbd_urb *urb, 
                     uint32_t flags,
                     void *addr, 
                     uint32_t len );

Arguments:

urb
An opaque handle (from usbd_alloc_urb()).
flags
One of the following:

You can optionally OR in the following:

addr
The address for the start of the transfer. You must use the buffer allocated by usbd_alloc().
len
The length (in bytes) of the data transfer.

Library:

libusbdi

Description:

This routine sets up a URB for a bulk data transfer.

Returns:

EOK
