Hi,<br><br>The host side drivers were compiled in, CONFIG_USB_OTG_WHITELIST was set off.<br>I could not get things up with the hub, so this time I cooked up a Y connector <br>with external power source(a usb port from desktop without d+ and d-),
<br>connected n800 and flash disk to other ends.<br><br>I was able to get the flash disk working only for a while, after a shutdown and start of n800 <br>it stopped working with the following errors in dmesg.<br>Have i messed up with something? Any clues / pointers?
