They should have some sort of discoverable property. There must be
some reason why you need a specific channel. I think of label as being
a sticker or silkscreen on a device which doesn't seem to be the case
here. This seems more like wanting fixed device numbering like disks
and I assume you know the position on fixed device numbers.
