So on openpli it's not gonna work, that's what you sayin' ?
I've looked in the manufacturer BSP (the software layer supplied by the manufacturer which contains the linux kernel and hardware drivers).
The driver is called hmp-usb-dvb-t2-c which means you won't find it in the driver section of the plugin lists, you need to install it from the commandline, or using the advanced options menu of the software management plugin.
It is available on my Duo 4K:
root@vuduo4k:~# opkg list | grep hmp hmp-usb-dvb-t2-c-arm - V160430-r1.5 - media tree drivers for hmp-usb-dvb-t2-c hmp-usb-dvb-t2-c-arm-dbg - V160430-r1.5 - media tree drivers for hmp-usb-dvb-t2-c - Debugging files hmp-usb-dvb-t2-c-arm-dev - V160430-r1.5 - media tree drivers for hmp-usb-dvb-t2-c - Development files
so
opkg install hmp-usb-dvb-t2-c-arm
and a reboot of the box from the menu should fix it.
