USB_INIT_URB(9) USB Core APIs USB_INIT_URB(9)
NAME
usb_init_urb - initializes a urb so that it can be used by a USB driver
SYNOPSIS
void usb_init_urb(struct urb * urb);
ARGUMENTS
urb
pointer to the urb to initialize
DESCRIPTION
Initializes a urb so that the USB subsystem can use it properly.
If a urb is created with a call to usb_alloc_urb it is not necessary to call this
function. Only use this if you allocate the space for a struct urb on your own. If you
call this function, be careful when freeing the memory for your urb that it is no longer
in use by the USB core.
Only use this function if you _really_ understand what you are doing.
