I have 2x 49 port hubs running they run 41 and 44 hubs each and I am running a 20 port hub.


one of my 49 port hubs has a bad row of 7  it has power but no hubs can be read on it.  it is okay as I am using a few of those 7 dead ports to power usb 3 fans.

I think a good mobo can do 3x  49 port hubs and up to 120 sticks  40 on each.  I have a third hub on the way.


 and I am using this 5 port  pcie usb2
