About a USB driver of LinuxBSP for i.MX6 Solo

Dear all,


We use i.MX6Solo.
And L3.0.35_4.0.0_130424_source.tar.gz is used.


We have some questions about Linux BSP.


In our system, we think about the following configuration.
We use this for the maintenance of our system. (like RS232C)


     [PC(USB Host)]<====[USB to serial]====>[i.MX6 original board(USB Device)]


In this case, we understand that we should use "g_serial" included in the USB gadget of Linux BSP.


We want to modify this "g_serial".
However, the "g_serial" is a module form.

Can "g_serial" be modified?


Is there the document about "g_serial"?


When we use USB like RS232C, is there the good idea?


We understand that the USB driver included in Linux BSP decides the operation of the USB port by a state of USB_OTG_ID.

      - Low => USB_OTG of i.MX6 works as Host.
      - High => USB_OTG of i.MX6 works as Device.

Is my understanding right?


May I have advice?


Best Regards,
