Yeah, that's what it sounds like to me too, but there doesn't seem to
be any way to figure out what's attached to that "hub".
I tried looked at how this might work in FreeBSD, but it looks like
they don't have a uhidev device at all, uhid's just attach to a uhubX
or directly on a usbusX (their name for usbX), so I assume that they
show up when iterating over the devices on a bus.

I suppose I can just try opening each of the /dev/uhidX device files,
but then the lack of ioctl USB_GET_DEVICE_DESC makes getting the product
and vendor ID's difficult.

This is looking more and more like it's going to require some kernel
changes to get it working. :(
