I've executed the following script, and got the result:
#!/bin/sh

echo 5 > /sys/module/musb_hdrc/parameters/debug
echo 8 > /proc/sysrq-trigger

sleep 1
insmod /tmp/g_mass_storage.ko file=/etc/firmware/disk stall=0
sleep 15
rmmod g_mass_storage
sleep 3
insmod /tmp/g_mass_storage.ko file=/etc/firmware/disk stall=0


value 15 can be increased if that time is not enough to get mass
storage mounted.
