Check e.g. http://mail-index.netbsd.org/current-users/2007/06/20/0002.html
and the rest from yesterday. At this moment, as soon as I attach a

If I attach a USB1.1 hub first, and then the disk, then it works, but
obviously  slowly.

Mine are different, but everything points to the ehci driver.
Initially I couldn't even boot unless I disabled it - that is under
-current amd64.
