No worries!  Will you please hit 'reply all' next time, so we keep the
mailing list on Cc?  Thanks. :)

Huh.  That's odd.  Maybe your device needs some initialization that the
usbhid driver does during its probe routine, but your own driver doesn't
do.  Out of curiosity, is your driver an in-kernel driver or an
out-of-tree userspace driver?

What would an EHCI addendum have to do with your particular bug?  Or is
this a different question?

Alan Stern would probably be the best person to ask this question, since
he's the EHCI maintainer.
