crossover cable question?

Please confirm or correct.

A crossover cable is used to connect a hub
to another hub through standard ports?

If at least on of the hubs has an "uplink" port
then you do not need a crossover cable, since
you can connect a standard patch cable to the
uplink on one and a standard port on the other?

Or any other two devices that don't have dedicated uplink ports or cable auto
sensing...

True again.

What - no third question? You were on a roll :-)

Well this is what I've always thought. But our hub
always had one node that was "slow", much slower
than the rest. So one day one of the guys in the office
unplugged the cable going into the hub port and plugged
it in to the hub uplink, thereby in essence having the
cable (plugged into both the uplink on the router and
the uplink on the hub) . And now all the nodes are
fast. I surmise what we thought was a patch cable
between the router and the hub was in fact a crossover
cable and now it's reversing the uplinks just like it
would on standard ports. Only thing is, two specific
nodes cannot see each other, all others can see
everyone and each of the affected nodes can see
everyone except the other said node. We have the
ports next to the uplinks empty. I cannot find out
what's causing this?
