With my old WNR2500 ( TOMATO firmware ) i use a HUB USB with some USB disk KEY and i have in my network environment the key with automatictly the name of the USB key mounted as :
SANDISK-32GB
HDD-2580GB-USB
....
The question is how i program / configure for make the same functionnality with last 18.x OpenWrt ?
I think that last openwrt use hotplug.json … ( Tomato use hotplug2.rules )
