Install USB storage on WRT32X and OpenWrt 18.06.2

Installing and Using OpenWrt
1

I changed my router to a Linksys WRT32X and OpenWrt 18.06.2.
On the previous one, I installed the USB storage quickly following the howto Using storage devices.
Now, after 2 days, I can't get it working...

opkg list-installed | grep usb

There is no /dev/sda file.
What I did wrong?
Thank you for you help

Does lsmod show the modules as installed?

What do you see in the logs when you plug in a USB device (after booted, once things quiet down)?

No dmesg message after plug in USB hard drive!!!
This hard drive was working on the previous router, I used it to log the router Lan link outage.

I tried another hard drive and got the dmesg

It should be good now with the second one
Thank you to point me the issue.
I'll let you know
