I tested it on an Intel Skylake box. On the gadget side, I loaded a serial
device (#modprobe g_serial). And then, connected it with a host.

On the gadget side, I run below scripts:

#!/bin/bash

for j in `seq 1 200`;
do
for i in `seq 1 50000`;
do
echo $i.$j > /dev/ttyGS0
done
done

And, on the host side,

#cat /dev/ttyACM0

Best regards,
Lu Baolu
