if automatic hostmode was possible, I had shipped it 16 months ago I:E: N900 has no way to auto-detect a Y-cable or a peripheral with normal cable and F-F-adapter (there's a more theoretical option to detect ID-to-GND short as you find it on A-plugs which don't fit into N900 B-receptacle. This needs pullup on ID though, which by default isn't enabled) /j
