So your Linux PDA shows up as a USB device when plugged into a USB host?
Or is it the other way around?

Yes. If you are a USB host you should get that event today. If you are
a USB device (what Linux calls a USB gadget), you should generate that
event, but as there is no mainline code for USB gadget's right now, I do
not think that has been hooked up yet.
Are you using the Lineo USB gadget code, or some other USB code?
thanks,
