The 7 port hub that I have is actually a pair of 4-port hubs chained together. There are 3 external ports on the first hub, the 4th goes to the second hub. All 4 ports on the second hub go to connectors. You might learn something by using one of the 3 ports that go to the first hub so there is only one hub in the data path. lsusb -t will draw you a picture. Just move a widget from port to port and see where it moves on the picture. -- These are my opinions, not necessarily my employer's.
