Re: [Gumstix-users] Overo and OTG USB

[Victhor F. <vic...@gm...>]

I had to build a new kernel. On the menuconfig screen, select the
following options:
Device Drivers -> USB support -> Inventra Highspeed Dual Role
Controller/Driver Mode. Select either "USB Peripheral (gadget stack)"
or "Both host and peripheral:  USB OTG (On The Go) Device"
Back on the previous screen ("USB support"), go to "USB Gadget
Support". Select as modules: "Mass Storage Gadget" and, if you need
USB host on the OTG port, "Gadget Zero (DEVELOPMENT)". Save your
configuration and build a new system image, or kernel as usual. Copy
the appropriate files to your rootfs.
To use the mass storage device driver:
modprobe g_mass_storage file=/dev/foo
e.g.:
modprobe g_mass_storage file=/dev/mmcblk0p2
will provide the host connected to the Overo with a mass storage
device that points to /dev/mmcblk0p2. Note that the host is performing
operations to this block device "transparently". For example: if
mmcblk0p2 is formatted as a FAT32 partition, it will appear as such to
the host. If it's formatted as ext3, it will appear as a
ext3-formatted disk to the host, etc. Word of advice: unmount the
block device to be used by g_mass_storage before using it.
g_file_storage is used in a similar way, but the "file=" argument
points to a "file-backed storage" file, not to a block device.
