Hi Alan,

In the updated patch this mechanism affects all bulk transfers, not
just bulk-IN. So for example, if a transient hardware problem causes a
bulk-OUT URB to fail, the remaining URBs in that transfer will
automatically be cancelled.
I will post the new patch shortly. The expectation is that it will get
into the next merge window, so it will appear in 2.6.32.
Digging up an old topic...
http://www.libusb.org/ticket/20 points out that OUT urbs with
SHORT_NOT_OK set generate warnings and rejects transfers in debug mode.
The debug code in usb_submit_urb() does indeed check that SHORT_NOT_OK
is only set on IN urbs.
Can we fix that inconsistency? Is the correct fix simply removing the check?
cheers
Daniel
