However, there is a problem with your specification: No hub (that I
am
aware of) can do 1Gbps. All hubs are 10/100 AFAIK.
Ok, so I guess what I am speaking is not strictly a hub, it is a non-
learning bridge (single collision domain per port, full duplex, etc).
There used to be a bunch of devices sold like this -- there were a few
really cheap chipsets (AFAIR, Vitesse SparX VSCsomething was one of
them -- basically a standard switch chipset that they shaved a few
cents off because there was no learning logic / memory) that many
people used in cheap "hubs"... I still have some of these somewhere
and will rip the lid off to figure out exactly what it was so I can
get some more...
And, note carefully: some "dual-speed hubs" are actually a 10BT hub
and
a 100BT hub *with a switch between them*. I forget which brand I
caught this on, but it bit me a couple of years back.
Which speed cable you plug in determines which hub you're talking to.
I see your weird hub story and raise you one:
I went along to one of my wife's clients to help lug a printer up the
stairs... We get it on the desk and I go to plug in the Ethernet port
-- I follow some cables and find this small white switch jammed behind
a photocopier -- I pull it out and it has, emblazoned in large red
letters on the front, "10/100 Hub with Switch" -- this was back in
the day when switches were still cool... I turn it around, and on the
back there is... a switch, one side is marked "10M" and the other is
marked "100M"... After I stopped laughing I tested it, and sure
enough, its a standard hub, and you can make the ports either run at
10Mbps or 100Mbps by flipping the switch... I *really* wish I had
replaced and kept it...

Yes, it's weird.
