OTG Reader not working

Hi guys. So I bought the otg micro sd reader and my mx4 pro doesn’t see it. My samsung a5 sees it and reader works no problem.
What should I do to make it work on meizu?

So I read whole internet and what I found is I probably don’t have USB host file… please tel me how to make it work on flyme? I don’t have system folder and etc folder with permissions. So how do I permit to host usb otg reader?

Meizu m3s

You do have a system folder, you just need a custom file explorer to view the root directory. I suggest the ES file explorer or root explorer. To modify these files you will require root (su). Btw host file should be in /system/etc/permissions/android.hardware.usb.host.xml and should already exist.

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
