Strange, works for me. At least USB 1.1 devices. What does
verbose boot
say or a kernel with USB_DEBUG?

Verbose boot doesn't really say more:

That basically looks like on i386.  Except on i386, if USB
devices
are connected or you plug them in, additional probes happen.
 On
my alpha nothing happens.  (Pristine GENERIC.)
