Wait a minute! The usb protocal supports lots of things, not just file devices. For example, I hook my motorola v3xx phone's target usb port to my mac usb host port and log into the internet just like I can do using bluetooth.

I ought to be able to do the same with my 810, but so far I have not been able to do it or to find any reference to someone else doing it,

Does anyone have an authoritative answer as to wether the 810 can do it?
