Take an unused USB-stick (or one which data you do not need any more) and create a "live system" with it. You can use "unetbootin" or any similar tool, you can even do it with
dd, there are thousands of how-tos in the internet, search for "create bootable USB stick linux".
Then put this stick into the system in question and boot from there. You may need to configure the BIOS accordingly so that it uses the USB stick to boot from.
I hope this helps.

EHCI(4) BSD Kernel Interfaces Manual EHCI(4)
NAME
ehci -- USB Enhanced Host Controller driver
SYNOPSIS
device ehci
DESCRIPTION
The ehci driver provides support for the USB Enhanced Host Controller Interface, which is used by USB 2.0 controllers.
EHCI controllers are peculiar in that they can only handle the USB 2.0 protocol. This means that they normally have one or more companion
controllers (i.e., ohci(4) or uhci(4)) handling USB 1.x devices. Consequently each USB connector is electrically connected to two USB con-
trollers. The handling of this is totally automatic, but can be noticed since USB 1.x and USB 2.0 devices plugged in to the same connector
appear to connect to different USB busses.
SEE ALSO
ohci(4), uhci(4), usb(4)
HISTORY
The ehci device driver first appeared in FreeBSD 5.1.
BUGS
The driver is not finished and is quite buggy.
There is currently no support for isochronous transfers.
