I have a Buffalo WZR-HP-G300NH2 and I'm trying to get USB support working. The original Buffalo-branded firmware would refuse to mount the USB drive, so I've followed what tutorials I've found for DD-WRT. I've tried ssh-ing into the box and mounting it with
mount /dev/sda /mnt
as root, and it fails with invalid arguments.
For USB file formats I've tried EXT3 and XFS. XFS is the user-friendly firmware file format.
I can enable FTP in the DD-WRT GUI and log in, but transferring anything bigger then 5MB to the 500GB attached drive causes the router to reboot.
I've downgraded to the Buffalo user-friendly firmware and it seemed to work, but I would like to get DD-WRT running; currently I'm running build 18024.
