OK... using the above info .. on the latest 0S2008 .. I can do this.

1. Enabled R&D mode (not tested outside this mode)

2. echo host > /sys/devices/platform/musb_hdrc/mode

3. Using female to female gender bender I conncected a USB keyboard to the n800.

4. It gives error message about unsupported device and then. POOF I have a keyboard.

5. Disconnected keyboard inserted USB key Drive.
It complained about unsupoorted device. Opened the File manager and POOF showed me the files.

6. Just for fun I plan on try a USB DVD reader and USB HDD (both with independent power) and see what I get.... wii!
