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
