Hi.
I use dm814x evaluation module and want to use usb file-backed storage gadget. The gadget module is compiled and inserted successfully, but PC doesn't even notice plugging of the device. The device is connected to PC through usb1. Usb0 holds usb mouse. I make first dummy inserting of zero gadget, because the firts inserted module take place on usb0 and only second on usb1.

So module inserts succesfully, so why PC cannot see it?
