usb_fill_int_urb — macro to help initialize a interrupt urb
void usb_fill_int_urb
(struct urb * urb, struct usb_device * dev, unsigned int pipe, void * transfer_buffer, int buffer_length, usb_complete_t complete_fn, void * context, int interval);
pointer to the urb to initialize.
pointer to the struct usb_device for this urb.
the endpoint pipe
pointer to the transfer buffer
length of the transfer buffer
pointer to the usb_complete_t function
what to set the urb context to.
what to set the urb interval to, encoded like the endpoint descriptor's bInterval value.
Initializes a interrupt urb with the proper information needed to submit it to a device. Note that high speed interrupt endpoints use a logarithmic encoding of the endpoint interval, and express polling intervals in microframes (eight per millisecond) rather than in frames (one per millisecond).
