Wait, your docking station connects with USB? What docking station is this?

It's probably acting as a USB hub, hence recognizing the USB mice etc, but those 'Dell Computer Corp' devices aren't necessarily recognized.

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. BSD March 20, 2005 BSD
