This patch (as567) formalizes this practice and adds code to usb_bulk_message() for detecting when the target is really an interrupt endpoint. If it is, the routine submits an interrupt URB (using the default interval) instead of a bulk URB. In theory this should help HCDs that don't like it when people try to mix transfer types, queuing both periodic and non-periodic types for the same endpoint. Not fully tested -- I don't have any programs that use USBDEVFS_BULK for interrupt transfers -- but it compiles okay and normal bulk messages work as well as before.
