I don't know what "code-less kext" is, but in NetBSD you can do this with
a custom kernel configuration that has a nailed down ugen entry, e.g.:
ugen3 at uhub? port ? vendor 0x06c2 product 0x0031 flags 1
The vendor and product you can get using the USB_GET_DEVICE_DESC ioctl, which
I recently copied over to uhid devices.
Unfortunately userconf (boot -c) doesn't seem to be capable enough to do this
so you actually need to build a new kernel for it.
