My external usb hdd enclosure doesn't work with the kernel packaged with the central. I have an enclosure based on the ALI562x chip. If someone else has a different one and wants to give it a shot, I have attached the kernel modules you need to load to make it work.

1. Use insmod to load usb-storage.o and all the scsi modules. (Yes, you need scsi drivers even though it is usb and ide.)
2. Plug in the usb drive.
3. Type "dmesg" and see if anything promising comes up.
