<p>168.9.19.101: </p> <hr /> <div>USB host mode allows you to connect various USB devices (external hard drives, digital cameras, card readers, input devices, etc.) to your device just like a regular computer. There are, however, a few limitations. The device must draw under 100mA (this can be bypassed by using a powered hub), and you will need a hardware adaptor to plug a fullsize USB cable into the tablet's undersized one.<br /> <br /> == USB On-The-Go ==<br /> <br /> The USB port on the tablets is a [http://en.wikipedia.org/wiki/USB_On-The-Go USB OTG], this means that they can be switched between client- (where you plug the tablet into a computer—for flashing and mounting cards on the computer), and host- (where the tablet acts like a computer) mode with the correct hardware adaptor.<br /> <br /> You can find a USB OTG adapter designed specifically for the [http://www.electronicproductonline.com/catalog/product_info.php?products_id=1781 N800] and the [http://www.electronicproductonline.com/catalog/product_info.php?cPath=35_67&amp;products_id=2004 N810] (N810 owners will need to buy both adaptors until a custom N810 adaptor is manufactured). These OTG adaptors will automatically switch the tablet into host-mode when plugged in.<br /> <br /> You can also buy a &quot;dumb&quot; adapter that will provide the correct connections, but will not automatically switch the tablet into host-mode from most online and some in-store retailers. Then you can simply switch into host-mode manually.<br /> <br /> == Switching modes with software ==<br /> <br /> There are two options for switching between client- and host-mode in software. If you want to switch modes using a statusbar application, install the [https://garage.maemo.org/projects/usb-otg-plugin/ usb-otg-plugin], if you prefer to use a separate application for switching modes, then install [http://maemo.org/downloads/product/OS2008/usbcontrol/ USB Control]. Both pieces of software accomplish the same thing, they just provide slightly different interfaces to do it.<br /> <br /> == Switching modes manually ==<br /> <br /> To manually switch USB modes, you must first have [[Root_access#rootsh|rootsh]] installed, then open xterm and type:<br /> sudo gainroot<br /> echo host &gt; /sys/devices/platform/musb_hdrc/mode<br /> <br /> The tablet will then be in host-mode and you can use your USB peripherals. To set the tablet back to client mode, open xterm again and type:<br /> echo otg &gt; /sys/devices/platform/musb_hdrc/mode<br /> <br /> <br /> [[Category:Users]]<br /> [[Category:USB]]</div>
