How to load modules

« on: March 05, 2006, 02:04:42 AM »

Noob Question:

I'm trying to active the USB ports on dd-wrt v23sp1 060303. I've basically followed Macsat's fine tutorial on activating USB in OpenWRT, with a couple of differences --

1. the modules file is not at /etc/modules, rather they're at /jffs/etc/modules.d/
2. 'logread -f' fails but 'more /var/log/messages' has the system log.

But when reading the log and the output of dmesg, I get no mention of USB anywhere. I'd very much appreciate it someone could point me in the right direction.

js

At loading with insmod I get the following error:

/jffs/etc/modules.d # ls -l
-rw-r--r-- 1 root root 9 Nov 23 21:41 30-ext3
-rw-r--r-- 1 root root 9 Nov 23 21:41 30-vfat
-rw-r--r-- 1 root root 8 Nov 23 21:41 50-usb-core
-rw-r--r-- 1 root root 8 Nov 23 21:41 60-usb-printer
-rw-r--r-- 1 root root 28 Nov 23 21:41 60-usb-storage
-rw-r--r-- 1 root root 5 Nov 23 21:41 60-usb-uhci
-rw-r--r-- 1 root root 9 Nov 23 21:41 60-usb2
/jffs/etc/modules.d # insmod 30-ext3
Using 30-ext3
insmod: error reading ELF header: Success
insmod: Could not load the module: Success

(Same error with the others.)

As far as I know there is no support for USB in DD-WRT.

As it is build on OpenWrt I guess it SHOULD be possible to do what you try, but are you sure you are getting the modules loaded correct with insmod?

There is a wiki on it...
http://wrt-wiki.bsr-clan.de/index.php?title=Ipkg

Using the 11 March DD-WRT build. Still no dice. Anyone have any ipkgs installed on DD-WRT?

Code:

/jffs/etc/modules.d # uname -a
Linux 2.4.33-pre2 #520 Sat Mar 11 00:45:02 UTC 2006 mips unknown
/jffs/etc/modules.d # ls -l

I have asus router 500gp with DD-WRT v23 SP2 (09/15/06) std. I managed to activate usb ports and printing.
But now I have problem with starting modules and printing deamon. Everytime when i reboot my router i have to start modules and printing deamon.
I tried with this tutorial http://www.dd-wrt.com/wiki/index.php/USB#Installation
but it didn't work.

This is how i activate usb ports and printing:
1.You have to enable jffs:

Code:

nvram set jffs_mounted=1
nvram set enable_jffs2=1
nvram set sys_enable_jffs2=1
nvram set clean_jffs2=1
nvram set sys_clean_jffs2=1
nvram commit

reboot

2.Installing USB drivers:

Code:

ipkg update

ipkg install kmod-usb-core
ipkg install kmod-usb2
ipkg install kmod-usb-storage
ipkg install kmod-usb-printer
ipkg install kmod-usb-uhci

3.Load modules:

Code:

insmod /jffs/lib/modules/2.4.30/usbcore.o
insmod /jffs/lib/modules/2.4.30/ehci-hcd.o
insmod /jffs/lib/modules/2.4.30/uhci.o
insmod /jffs/lib/modules/2.4.30/scsi_mod.o
insmod /jffs/lib/modules/2.4.30/sd_mod.o
insmod /jffs/lib/modules/2.4.30/sg.o
insmod /jffs/lib/modules/2.4.30/usb-storage.o
insmod /jffs/lib/modules/2.4.30/printer.o

4. Installing and starting printer server:

Code:

ipkg install p910nd

Than you have to go to folder

Code:

/jffs/etc/init.d

and changed path in file S70p910nd
from

Code:

DEFAULT=/etc/default/p910nd

Code:

DEFAULT=/jffs/etc/default/p910nd

and than you can start deamon with

Code:

/jffs/etc/init.d/S70p910nd start

if you see

Code:

p9100d -b -f /dev/usb/lp0 0

when you do command "ps" deamon is working.

I found solution for my problem. http://www.dd-wrt.com/wiki/index.php/User_talk:Oxo#.2Fjffs.2Fetc.2Fconfig.2F.2A.startup

v23 starts executable files in /jffs/etc/config/*.startup

/jffs/etc/config/S10modules.startup

ipkg sometimes make modules.d files: like for USB. So make the following to insmod these modules

Code:

#!/bin/sh
for module in $(cat /jffs/etc/modules.d/*);do
/sbin/insmod /jffs/lib/modules/2.4.30/$module.o
done

/jffs/etc/config/S90init.startup

ipkg sometimes make init.d files

Code:

#!/bin/sh
$(/jffs/etc/init.d/S* start)

The problem was that my startup scripts didn't have permission to execute. So i changed permission.

Sorry for my english.
