[[Image:linux_config_usb_gadget.png]]

* save your configuration and then rebuild your kernel image:
<pre class="host">
 $ make
</pre>
now you should have the following drivers in your kernel source tree:
 '''/lib/modules/`uname -r`/kernel/drivers/usb/gadget/gadgetfs.ko'''        For test
 '''/lib/modules/`uname -r`/kernel/drivers/usb/gadget/g_ether.ko'''         Ethernet emulation on USB
 '''/lib/modules/`uname -r`/kernel/drivers/usb/gadget/g_file_storage.ko'''  Mass storage
 '''/lib/modules/`uname -r`/kernel/drivers/usb/gadget/g_serial.ko'''        Serial emulation on USB
 '''/lib/modules/`uname -r`/kernel/drivers/usb/gadget/g_zero.ko'''          For test
 '''/lib/modules/`uname -r`/kernel/drivers/usb/gadget/imx_udc.ko'''         i.MXL USB device Core Controller 

* reflash your RootFS or manually copy ''imx_udc.ko, g_file_storage.ko & g_serial.ko'' to your target in /lib/modules/...

==Usage==

First, load the core controller driver on your board:
 # modprobe imx_udc
  usb: imx_udc version: 0.5
