Default [INFO] ME301T MemoPad 10 OTG not working in custom rom??

Hi everyone, I've recently rooted and unlocked my tablet and tried different custom rom (Omnirom 6 BeanStalk which is my current daily driver and I find it increbible).

The only thing I found not working is OTG (Usb host) as it doesn't read any kind of usb drives, mouse, keyboard, etc even if it recognizes a usb device connected.

I even tried third party apps but no luck.

Is it me or there's a problem with OTG? Are there any workaround for this??

Thank you all
