I've noticed this problem too and reported it to the dev list; it's
also been reported on the linux-kernel list. Hopefully David Brownell
(the maintainer) will have a work around.

If you want a temporary kludge which works for me (YMMV), locate
the line calling ehci_reset() in ehci-hcd.c:ehci_start() and ignore the
return value (the default behaviour is for ehci_start() to indicate
an error if ehci_reset returns non-zero, this causes the driver
to be unloaded. In my case and I guess yours, ehci_reset is indeed returning
a non-zero value).
