Gotcha!
During some walkthrough along the interrupt-urb paths of usb-uhci and the
single-shot case in particular I stumbled over a line which I really
doubt is what it is supposed to. Seems there are some parentheses missing
and nobody really used that stuff for some time ;-)
The patch below should fix this issue. At least for me everything is fine
now, i.e. both single-shot and periodic int transfers working with all
three usb-ohci, usb-uhci and uhci(JE).
