 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.
