Hi Experts,
I've been struggling with an issue of usb doesn't show up after I configure usb support as shown in the attached picture. This has been the case since I started using this router with dd-wrt (about 1.5 years).
Now I need the usb support because of my plan to extend the configuration.
Things tried so far:
- multiple version of dd-wrt firmware have been tried. Currently I'm using build 44715.
- searched online and on dd-wrt forum, and tried https://wiki.dd-wrt.com/wiki/index.php/USB_storage
- exFat, FAT32, NTFS, file systems have been tried.
- tried multiple usb storage devices.
- tried both usb ports on the router.
but no success so far.
Can someone help in this? I would be really thankful.

@hellf:
Based on your suggestion, I formatted the usb storage with ext4, started a new terminal with "watch -t -n 1 lsusb" and tried the both usb ports but nothing shows up in the terminal.
@IONK:
Yes, I've tried multiple USB storage devices, like: Kingston, Sandisk, Western Digital.
I've tried the instructions of how to mount the usb from the document but no success.

You should consider upgrading from 44715. If you say that it is the latest, then you are not looking past the doorway and will continue to have issues.
As per the suggestion, I've upgraded the router to the latest build (47074) and tried again with NTFS, ext2 and ext4 file systems with three types of USB storage devices and on both ports of the router. But no success.
Here are the output of nvram, dmesg and lsmod:
