For an URB which you've submitted, but which hasn't been returned to

There are two ways to cancel an URB you've submitted but which hasn't
been returned to your driver yet. For an asynchronous cancel, call
int usb_unlink_urb(struct urb *urb)
It removes the urb from the internal list and frees all allocated
HW descriptors. The status is changed to reflect unlinking. After
usb_unlink_urb() returns with that status code, you can free the URB
with usb_free_urb().
HW descriptors. The status is changed to reflect unlinking. Note
that the URB will not normally have finished when usb_unlink_urb()
returns; you must still wait for the completion handler to be called.
There is also an asynchronous unlink mode. To use this, set the
the URB_ASYNC_UNLINK flag in urb->transfer flags before calling
usb_unlink_urb(). When using async unlinking, the URB will not
normally be unlinked when usb_unlink_urb() returns. Instead, wait
for the completion handler to be called.
To cancel an URB synchronously, call
void usb_kill_urb(struct urb *urb)
It does everything usb_unlink_urb does, and in addition it waits
until after the URB has been returned and the completion handler
has finished. It also marks the URB as temporarily unusable, so
that if the completion handler or anyone else tries to resubmit it
they will get a -EPERM error. Thus you can be sure that when
usb_kill_urb() returns, the URB is totally idle.
1.7. What about the completion handler?
The handler is of the following type:
typedef void (*usb_complete_t)(struct urb *);
typedef void (*usb_complete_t)(struct urb *, struct pt_regs *)
i.e. it gets just the URB that caused the completion call.
I.e., it gets the URB that caused the completion call, plus the
register values at the time of the corresponding interrupt (if any).
In the completion handler, you should have a look at urb->status to
detect any USB errors. Since the context parameter is included in the URB,
you can pass information to the completion handler.

Note that even when an error (or unlink) is reported, data may have been

@ -229,24 +231,10 @@ ISO data with some other event stream.
Interrupt transfers, like isochronous transfers, are periodic, and happen
in intervals that are powers of two (1, 2, 4 etc) units. Units are frames
for full and low speed devices, and microframes for high speed ones.
Currently, after you submit one interrupt URB, that urb is owned by the
host controller driver until you cancel it with usb_unlink_urb(). You
may unlink interrupt urbs in their completion handlers, if you need to.
After a transfer completion is called, the URB is automagically resubmitted.
THIS BEHAVIOR IS EXPECTED TO BE REMOVED!!
Interrupt transfers may only send (or receive) the "maxpacket" value for
the given interrupt endpoint; if you need more data, you will need to
copy that data out of (or into) another buffer. Similarly, you can't
queue interrupt transfers.
THESE RESTRICTIONS ARE EXPECTED TO BE REMOVED!!
Note that this automagic resubmission model does make it awkward to use
interrupt OUT transfers. The portable solution involves unlinking those
OUT urbs after the data is transferred, and perhaps submitting a final
URB for a short packet.
The usb_submit_urb() call modifies urb->interval to the implemented interval
value that is less than or equal to the requested interval value.
In Linux 2.6, unlike earlier versions, interrupt URBs are not automagically
restarted when they complete. They end when the completion handler is
called, just like other URBs. If you want an interrupt URB to be restarted,
your completion handler must resubmit it.
