Been looking for this but cant seem to find any information.

I want to use the USB ports on the Dlink 882 router. I have it flashed with build 43471(19/06/2020). However I am unable to mount the USB HDD. Formatted the disk as ext3 and followed instructions on the website but to no avail.

Any help is appreciated.

Thank you all,

Via telnet/ssh to the router, you can do lsmod to see what kernel modules are loaded. You can also check in /lib/modules/(kernel version)/ using ls to see if any ext*.ko files exist. If they do not, then ext* filesystem support is not in the firmware for this device. I am willing to bet that it only supports msdos, vfat or fat, and ntfs.

I sshd into the router and saw that it has ext4.ko files. I guess it has ext4 support. I then formatted my external HDD as ext4 and attached it back to the router. Rebooted but alas the HDD still does not show when I go to services->usb.

Lsmod does not show ext4 in the list. How do I load the module?

insmod ext4

For it to survive a reboot, you will need to add it to your startup script.

Well, I faced a similar issue and was able to fix it by explicitly inserting xhci-mtk kernel module.

Can you try by adding below command in your start-up script? You can even try executing it over SSH and see if USB HDDs are getting detected.

insmod xhci-mtk.ko
