Tom, Georg,

Any results, patches on this subject?

Personally I'd like to see us remove one-shot
interrupts.  It was added to the URB rewrite for
backwards-compatibility usage for usb_scsi (now
usb-storage), which no longer uses it.

The suggestion to use a bulk transfer request
in place of a one-shot interrupt does have a
downside -- one that I expect Tom would discover
even if we didn't bring it up.  Interrupt transfers
fall into the guaranteed bandwidth area of USB
[if usb_submit_urb() doesn't return an error],
whild bulk transfers have no such guarantee.
This could make a difference on a device like a
force-feedback joystick while other guaranteed
bandwidth transfers are occurring, like large Isoc.
camera input transfers.
