Hello Gene,

it is the same netbook. I have windows XP and grml linux (Kernel 2.6.31,  
squeeze) running. If i connect the voyager into another usb-port of the  
netbook, the voyager works well.
If the voyager is connected into the usb-hub, the braille-cells will work,  
but the keys of the braille-display and the routing-keys will not work.


The command lsusb with vendor-id of the 7x usb-hub will be as:
