I hereby pronounce that weird.
A few things you might want to try:
* Linux handles USB devices slightly differently if they're hotplugged
(plugged in while the computer is turned on). You might see if that
makes any difference: Remember that you can try unplugging and
replugging the hub as well as the devices.
* What sort of USB subsystem do you have? Try lspci | grep -i usb
Some PCs will have two different USB controllers, and you could try
plugging the hub into a different port.
* What happens if you only have one device plugged into the hub: does
lsusb see them then? (You might as well try each of the devices).
* Is the hub powered or unpowered? (Does it have a separate power
supply?) If not, then you could be finding that the power to the hub
is marginal.
Hope this helps,
James.
