6 usb_init_urb - initializes a urb so that it can be used by a USB driver
7
9 void usb_init_urb(struct urb * urb);
10
12 urb
13 pointer to the urb to initialize
14
16 Initializes a urb so that the USB subsystem can use it properly.
17
18 If a urb is created with a call to usb_alloc_urb it is not necessary to
19 call this function. Only use this if you allocate the space for a
20 struct urb on your own. If you call this function, be careful when
21 freeing the memory for your urb that it is no longer in use by the USB
22 core.
23
24 Only use this function if you _really_ understand what you are doing.
