xdaのやつでできたけど。
otg用ケーブル忘れずにね

- install from Playstore Universal Init.d
- Open Universal Init.d and activate support 
- Create a generic text file Ex. usbotg in /etc/init.d folder with the following content
#!/system/bin/sh
echo hoston > /sys/devices/f4000000.hisi_usb/plugusb

!!!! Replace "f4000000" with the value found in your smartphone (my: ff100000) !!!!
- give to the file 755 permission
- reboot

I used Root Explorer to do all.
