There's a lengthy thread discussing the N900 and things usb at http://talk.maemo.org/showthread.php...hlight=usb+otg

My understanding from reading most of that is that usb host might be possible for some applications, but a very good chance that it's not, and that there's really very very little chance that the N900 will be able to power other devices without using a powered usb hub.

Certainly, my impression is that usb host won't be possible out of the box.

I'd love for someone to correct me on any of the above though!
