USB Device not detected



Hii,

When i am trying to insert insmod /lib/modules/4.1.13-g8dc6617/kernel/drivers/usb/gadget/legacy/g_mass_storage.ko file=/dev/ram0 stall=0

I am getting like this

I think usb is successfully initialised but no device is getting detected. What can be the reason?

Thanks & Regards,
