USB Info
DD-WRT USB
- The USB port is where you can connect an external USB hard drive or flash drive.
- Which can do a multitude of things. You can use in as a NAS, storage for a FTP
- server, use Optware to run external programs like torrent software, samba for
- sharing files to network, share a USB printer with network...
- The list of possibilities is long, it just takes a little research.
- ProFTPd is included in most the newer builds of dd-wrt.
- Check the features chart to be sure.

Notes
jffs Issue in DD-WRT
This problem is caused by the firmware encountering an unmarked bad block during an
- erase operation while attempting to setup a JFFS2 filesystem on device /dev/mtd/4.
Most people will probably never experience this problem. The AC66U, the D1800H, and
- the Buffalo WLI-H4-D1300 Media Bridge use the same Samsung flash memory chip.
In case, 4 of 5 D1800H's had the problem but D1300 didn't. Neither of AC66U's had the problem.
- One person on one of the AC66U threads reported having the problem; here's a link to his post.
If you have the problem, you will not be able to create or copy directories and files to /jffs.
- Here are some example error messages: (this list was shortened to save space - it can go on for several pages)
root@WZR-D1800HRT2:~# dmesg|grep jffs
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x05ee0020: 0xe952 instead
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x05ee0024: 0x0e6d instead
jffs2: Further such events for this erase block will not be printed
jffs2: Old JFFS2 bitmask found at 0x05efc7fc
jffs2: You cannot use older JFFS2 filesystems with newer kernels
jffs2: Cowardly refusing to erase blocks on filesystem with no valid JFFS2 nodes
jffs2: empty_blocks 379, bad_blocks 1, c->nr_blocks 760
Also the Status -> Router webpage will show that JFFS2 has no free space.
To fix this problem try the following at a command line prompt:
flash_erase -j /dev/mtd/4 0 0 && reboot
This command erases and marks bad any bad blocks encountered so that they can be "skipped"
- and formats the partition to JFFS2 specifications.
I believe the firmware uses the mtd erase command which seems to fail at handling bad blocks.
- The flash_erase command needs to be run only once.
