[Fwd: Re: USB 2.0 Support (re-post, more info)]

Any truth to the ehci(4) having stability problems in >= 6.0-RC1 ? Or has this 
only been a problem in 5.4-RELEASE or earlier?

USB 2.0 support is provided by the ehci(4) driver, which is not in a
default install.  It is also buggy, at least in 5.4-R.  I use Firewire
for large external drives.
