See my previous post http://maemo.org/pipermail/maemo-developers/2006-November/006133.html [Working Peripherals for Wired Networking and Serial and powering Nokia from Hub] There is another post about patching the kernel if you happen to use the same USB network thing as me but that may be fixed in the version 3 IT2006 I haven't tested it yet but I assume it has a newer kernel and the issues had been resolved in newer kernels. It has part numbers in their for things including the camera power adapter I used. I will be testing the same setup with IT2006 v3 on the 770 and IT2007 on the 800 sometime soon.
