Sorry to reply without being an owner, but I've been struggling with an iliad today with a similar problem. If you get
usb 2-4: device descriptor read/64, error -110
usb 2-4: new full speed USB device using ohci_hcd and address 8
usb 2-4: device not accepting address 8, error -110
Then it looks like it's a kernel problem with the newer 2.6.3x's. I had working for awhile, but after digging around and enough rebooting for half a year I still haven't got a solution. Except for waiting.
