Ok, so what I'm assuming is happening here is that the device is plugged
into a port that's flagged "removable", but contains a built-in hub and
the receiver is attached to *that*. So this code really needs to look
back up the chain and see whether the parent port was removable or not.
I think the kernel is arguably ok here, and the udev rule needs fixing.
Let me talk to Kay.
