I have these udev rules for an IDE-to-USB device:
It generates the symlinks /dev/hotswap-bay1, /dev/hotswap-bay2, etc. when the device is detected. You may wish to forgo the symlinks and just make the device itself named that instead of whatever the kernel gives it, i.e. %k.
Note that debian probably keeps its local rules in a slightly different filename, though it does apparently have /etc/udev/rules.d
This page from the debian wiki shows you how to obtain the parameters to identify the device with.

ehci
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), xhci(4)HISTORY
The ehci device driver first appeared in FreeBSD 5.1.
LOADER TUNABLES
When the kernel has been compiled with options USB_DEBUG, some tunables become available that affect the behavior of ehci. These tunables
can be set at the loader(8) prompt before booting the kernel or stored in loader.conf(5).
hw.usb.ehci.lostintrbug
This tunable enables the lost interrupt quirk. The default value is 0 (off).
hw.usb.ehci.iaadbug
This tunable enables the EHCI doorbell quirk. The default value is 0 (off).
hw.usb.ehci.no_hs
This tunable disables USB devices to attach like HIGH-speed ones and will force all attached devices to attach to the FULL- or LOW-
speed companion controller. The default value is 0 (off).
