usb2 under 5.2, how to use ehci

[Graaf, Rob]

Hi,

i'm running FreeBSD 5.2.1 (installed right-out-of-the-box)
and make use of a LaCie external harddisk which is connected
by usb.

The usb driver used is uhci, but this supports only usb1,
which is not fast.

How can I use ehci, which seems to support usb2?

My dell laptop has a dual boot with winxp, which does support
usb2 and works fine.

Anybody can give me directions how replace the ehci?

Thanks
