USB_INIT_URB(9) USB Core APIs USB_INIT_URB(9)NAMEusb_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.
