You could try looking at the output of dmesg ("dmesg | less"). There
should be something about the usb subsystem finding the device, and then
the SCSI system making a fake SCSI disk /dev/sda or something.

If nothing is happening, your USB hub probably isn't being seen. For a
start, do "lsmod | grep hcd". This will show you which of the ohci-hcd,
uhci-hcd and ehci-hcd modules are being used. Depending on the computer,
you need different ones (in fact, my laptop has two different grrr..).

If not all three are present, try "modprobe <u|e|o>hci-hcd" (depending
on the module) and see whether pretty lights start.

Another way of checking whether it's the hub is to plug a USB optical
mouse in. If the hub's enabled, the mouse is powered and the light turns
on. :)

Let us know how you get on,

Rupert
