Is this definitely the case? The reason I ask is that looking at http://mos.futurenet.com/techradar/c..._12-420-90.jpg and http://en.wikipedia.org/wiki/File:Types-usb_new.svg it looks like the N900 has a micro-B socket. USB-OTG devices are required to have a micro-AB socket (a square one without the bevelled corners). If it doesn't take micro-A plugs, then either it doesn't support host mode, or it doesn't comply to standards, or wikipedia is wrong. http://en.wikipedia.org/wiki/Univers...-AB_Socket_OTG
