I have been able to switch the 770 usb to host mode and then I connected a usb flash drive to the usb port of the 770. I am injecting the required 5v to the flash drive and the 770. I see the following messages in dmesg: [68094.508758] USB cable connected [68095.097320] g_file_storage gadget: File-backed Storage Gadget, version: 20 October 2004 [68095.097412] g_file_storage gadget: Number of LUNs=1 [68095.097503] g_file_storage gadget-lun0: ro=0, file: /dev/mmcblk0 What do I need to do to actually mount the external flash drive?
