If it's not an interrupt or a bulk, what is it?
It _is_ an interrupt endpoint.
usb_bulk_msg() should work just fine for interrupt endpoints and bulk
endpoints. What are you trying to connect to here?
It should, but it doesn't. On one system (VIA EDEN with Gentoo
2.6.15) it works fine. On another system (Pentium M, not sure which
chipset, Gentoo 2.6.16) it doesn't work at all. On the Pentium system
it always returns -EINVAL. Both systems are EHCI.
For this reason I am suggesting a usb_intr_msg() function which is
written as usb_bulk_msg() but with usb_fill_int_urb() instead of
usb_fill_bulk_urb().
Regardless, I have grown fond of my completion variable solution since
it will keep me from having to use kthreads to achieve some of my
goals.

I understand, I had multiple statements in that block earlier and
removed them but never collapsed the {}.
Thanks.
