Hi all,

I'm successfully using my N800 in USB host mode with the GoldX cable kit that was mentioned in the N810 thread. (No auto-switching with this cable, either.) I picked up a cheap powered hub based on the Genesys Logic GL850A chip, which seems to work fine, and is cute as a button to boot.

The biggest problem with the hub, though, is that although it can operate in bus-powered or self-powered mode, it always reports to the host that the AC wall adapter is attached. This seems a bit dangerous--if the user connects four current-hungry devices without supplying external power, I don't see what would prevent the hub from attempting to suck 2+ amps out of the upstream port. I don't intend to ever use this device in bus-powered mode, so I'm not too upset, but I'm a little concerned about inadvertently disconnecting the AC power during heavy current draw. I could see this happening if I accidentally plug into a switched outlet in a hotel room, for example.

So, my question is--does the N800 have any sort of over-current protection? Would it damage the device to suddenly attempt to draw an amp or so from the onboard USB port?
