.BI "void usb_init_urb(struct\ urb\ *\ " "urb" ");"
.SH "ARGUMENTS"

.SH "DESCRIPTION"
.PP
Initializes a urb so that the USB subsystem can use it properly\&.
.PP
If a urb is created with a call to
\fBusb_alloc_urb\fR
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\&.
.PP
Only use this function if you _really_ understand what you are doing\&.
