Just upgraded our RT-N16 with v1.28.7494 with USB, VPN, VLAN. Everything is working fine except that I when I connect an external DVD-ROM drive it won't mount. When I click on the 'Mount' link to force a mount, I get an error message "Failed to mount. Verify the device is plugged in, and try again." The device is plugged in and there's a readable disc inside the drive.
Any reasons for the error? Are USB external DVD-ROM drives mountable? Thanks.
