Then you must load the gadget serial driver. To load it as an

- modprobe g_serial use_acm=1

To load it as a vendor specific bulk in/out device, do this:
- modprobe g_serial

This will also automatically load the underlying gadget peripheral
controller driver. This must be done each time you reboot the gadget
