This is a courious question from my experience.
I flashed openwrt firmware to my wndr4700 router.
If Internal Disk not installed, wndr4700 recognize usbs well.
But if Internal Disk was installed, wndr4700 can not recognize usbs and so on after that in spite of the interanl disk removed.
So I finally decided to reflash firmware to the router.
What's the problem in this case?
How can I fix it?
using openwrt firmware version: 21.02.01~03
Same router and OpenWrt 21.02.1, r16325-88151b8303 here.
