ok, but this is completely new behaviour. i took a look at the usbcdc11.pdf
and it describes a mechanism how different interfaces are linked together
to one functional unit in section 5.2.3.5 (Union Functional Descriptor).
instead of randomly picking a intr endpoint from some other random interface,
you need to figure out how the standard mechanism works.
this will also help you making sense of the openbsd driver.
remember, cdc is a generic standard. there could indeed be devices having
multiple ports.
