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.
