Hi konttori, i did not have any luck on my N810. Neither of my memorysticks (128 MB / 4GB FAT32) are recognized (Control-LED on Stick goes not on). When i put usb host on, leave the application and start it again, there is always otg activated. I looked up the file /sys/devices/platform/musb_hdrc/mode and there was only b_idle written in it (also after activating host without leaving the app). I even installed becomeroot just in case this would be necessary for any kind of write permission but no luck. You have any ideas ? Thanks MiBi
