Hi:
I'm currently planning to run dummy_hcd with usb_storage and g_file_storage in
my
linux whose kernel version is 2.6.13.4.The present situation is dummy_hcd
and usb_storage can be loaded successfully,but g_fie_storage failed.when i use
the
following module load command:
#insmod g_file_storage.ko file=/my_file
I got this messge:
insmod: error inserting 'g_file_storage.ko': -1 No such device
Here is the dump from lsmod:

And the following is the dump from dmesg:

Initializing USB Mass Storage driver...
usbcore: registered new driver usb-storage
USB Mass Storage support registered.
Finally,there is the configuration info about USB gadget in .config file:
#
# USB Gadget Support
#
CONFIG_USB_GADGET=y
CONFIG_USB_GADGET_DEBUG_FILES=y
CONFIG_USB_GADGET_SELECTED=y
CONFIG_USB_GADGET_NET2280=y
CONFIG_USB_NET2280=y
# CONFIG_USB_GADGET_PXA2XX is not set
# CONFIG_USB_GADGET_GOKU is not set
# CONFIG_USB_GADGET_LH7A40X is not set
# CONFIG_USB_GADGET_OMAP is not set
# CONFIG_USB_GADGET_DUMMY_HCD is not set
CONFIG_USB_GADGET_DUALSPEED=y
# CONFIG_USB_ZERO is not set
# CONFIG_USB_ETH is not set
CONFIG_USB_GADGETFS=m
CONFIG_USB_FILE_STORAGE=m
CONFIG_USB_FILE_STORAGE_TEST=y
# CONFIG_USB_G_SERIAL is not set
When configing the kernel,I do not set the CONFIG_USB_GADGET_DUMMY_HCD, but
compile the dummy_hcd module individually by myself.I have no idea that what's
wrong with it.Anyone could provide any clue about this will be appreciated very
much.
Best regadrs!
Jim
