This is how I would like to setup the gadget with mass storage (udc interface unchanged, so no udc choice for user; configfs root for the gadget is named "usb-function-gadget", probably to be changed after the udc-core supports choice of other than first available; some names probably to be changed as well, e.g. iManufacturer->manufacturer or something like that, connect->ready): $ insmod libcomposite.ko $ insmod g_usb_functions.ko $ mount -t configfs none /cfg $ mkdir -p /cfg/usb-function-gadget/ufg/config1/function1 $ echo -n <some id> > /cfg/usb-function-gadget/ufg/idVendor $ echo -n <some id> > /cfg/usb-function-gadget/ufg/idProduct $ echo -n <something> > /cfg/usb-function-gadget/ufg/bcdDevice $ echo -n <string> > /cfg/usb-function-gadget/ufg/iManufacturer $ echo -n <string> > /cfg/usb-function-gadget/ufg/iSerialNumber $ echo -n <string> > /cfg/usb-function-gadget/ufg/iProduct $ echo -n "f_mass_storage" > /cfg/usb-function-gadget/ufg/\ config1/function1/name $ mkdir /cfg/usb-function-gadget/ufg/config1/function1/\ f_mass_storage $ echo -n 1 > /cfg/usb-function-gadget/ufg/config1/function1/\ f_mass_storage/luns $ mkdir /cfg/usb-function-gadget/ufg/config1/function1/\ f_mass_storage/lun0 $ echo -n "file.img" > /cfg/usb-function-gadget/ufg/config1/\ function1/f_mass_storage/lun0/file $ echo -n 1 > /cfg/usb-function-gadget/ufg/connect With serial I would do the following: $ insmod libcomposite.ko $ insmod g_usb_functions.ko $ mount -t configfs none /cfg $ mkdir -p /cfg/usb-function-gadget/ufg/config1/function1 $ echo -n <some id> > /cfg/usb-function-gadget/ufg/idVendor $ echo -n <some id> > /cfg/usb-function-gadget/ufg/idProduct $ echo -n <something> > /cfg/usb-function-gadget/ufg/bcdDevice $ echo -n <string> > /cfg/usb-function-gadget/ufg/iManufacturer $ echo -n <string> > /cfg/usb-function-gadget/ufg/iSerialNumber $ echo -n <string> > /cfg/usb-function-gadget/ufg/iProduct $ echo -n "f_serial" > /cfg/usb-function-gadget/ufg/config1/\ function1/name $ mkdir /cfg/usb-function-gadget/ufg/config1/function1/f_serial $ echo -n 1 > /cfg/usb-function-gadget/ufg/config1/function1/\ f_serial/use_acm $ echo -n 1 > /cfg/usb-function-gadget/ufg/config1/function1/\ f_serial/n_ports $ echo -n 0 > /cfg/usb-function-gadget/ufg/config1/function1/\ f_serial/use_obex When the udc-core supports multiple udcs in a manner more flexible than the "first available", the "usb-function-gadget" name would be changed to e.g. /cfg/usb-gadget/gadgets. Also, the "connect" aka "ready" attribute could be changed to creating a symlink. Setting e.g. maximum power would be done through an appropriate attribute: $ echo 500 > /cfg/usb-gadget/gadgets/ufg/config1/maximum_power.
