I have. In fact, on one of the hubs, the thinwire is not the end of the 
loop so I have to. On this hub I can't set internal termination.

I've tried it on the other hub, and it seems to have solved, but only for 
a short while. I now have the same problems again.

I've ordered a new hub, maybe that will solve the problem.
