Hi! I'm facing a strange problem with an WNDR3700 v4 router with OpenWRT 18.06.0.
I have a SAMSUNG M3 portable USB hard drive attached. On LEDE 17.01 it worked fine. After upgrading to 18.06.0 it stopped working.
Debugging a little I've found that usb-storage kernel drive works with other USB sticks, but it is not working with the SAMSUNG HD anymore.
Here are some logs:
