Then you must load the gadget serial driver. To load it as an
ACM device (recommended for interoperability), do this:
modprobe g_serial use_acm=1
modprobe g_serial
To load it as a vendor specific bulk in/out device, do this:
modprobe g_serial
modprobe g_serial use_acm=0
This will also automatically load the underlying gadget peripheral
controller driver. This must be done each time you reboot the gadget
