The Nokia 770 ships with the usb connector in client mode and needs to be
reset into host mode. Once that is done it will act just like you would
expect from any Linux box.
The only caveat is that the 770 does not provide power through the usb
controller and in fact does not even power up the internal controller chip.
So the adapter I made simply provides 5 volt power to all the controller chip
and all the usb devices in order to make things happen.
Believe it or not the biggest problem is actually the Internet Tablet 2006
software. You can find it at maemo.org but I haven't messed with it much. As
far as I can tell it is a window manager that relies on pen input.
