Dumb question - does the hub have its own power supply, or is it
powered by the USB connection?
Mikkel
Devices connect to the USB hub get their power from the USB port
and if the hub does not supply enough power it won't work
many usb-hubs have only enough power for devices like keyboard and mouse
there are even usb disks out there which needs TWO usb-connections
one for data and one for power
devices gets their power from an external supply.
