USB
Installation
- Install the folowing modules :
ipkg install kmod-usb-uhci // this is for USB 1.1 ipkg install kmod-usb-core ipkg install kmod-usb2 ipkg install kmod-usb-storage
- For DD-WRT v23 or below, add the follwing script to startup. It executes on every reboot all *.startup scripts located in /jffs/etc/config/
console mode > ~ # nvram set rc_startup=" > for I in `/bin/ls /jffs/etc/config/*.startup` > do > sh $I & > done > " > ~ # nvram commit > web interface mode for I in `/bin/ls /jffs/etc/config/*.startup` do sh $I & done
A startup script must be made to start usb drivers on every reboot. Create a file, usb.startup in /jffs/etc/config/ directory that contains this :
#!/bin/sh 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/scsi_mod.o insmod /jffs/lib/modules/2.4.30/usb-storage.o # remove the dash (#) from the line below if you use USB 1.1 #insmod /jffs/lib/modules/2.4.30/uhci.o insmod /jffs/lib/modules/2.4.30/sd_mod.o
This is it. Here's my dmesg from Asus WL-500gP
dmesg SCSI subsystem driver Revision: 1.00 Initializing USB Mass Storage driver... usb.c: registered new driver usb-storage USB Mass Storage support registered. uhci.c: USB Universal Host Controller Interface driver v1.1 PCI: Enabling device 01:03.0 (0000 -> 0001) uhci.c: USB UHCI at I/O 0x100, IRQ 2 usb.c: new USB bus registered, assigned bus number 2 hub.c: USB hub found hub.c: 2 ports detected PCI: Enabling device 01:03.1 (0000 -> 0001) uhci.c: USB UHCI at I/O 0x120, IRQ 2 usb.c: new USB bus registered, assigned bus number 3 hub.c: USB hub found hub.c: 2 ports detected
Now to access FAT/EXT/XFS partitions you must install
ipkg install kmod-vfat ipkg install kmod-ext2 ipkg install kmod-ext3 ipkg install kmod-xfs
Add to /jffs/etc/config/usb.startup
# FAT insmod /jffs/lib/modules/2.4.30/fat.o insmod /jffs/lib/modules/2.4.30/vfat.o #XFS insmod /jffs/lib/modules/2.4.30/xfs.o
Now dmesg should show (The example below is from a 80 GB HD)
Attached scsi disk sda at scsi0, channel 0, id 0, lun 0 SCSI device sda: 156301488 512-byte hdwr sectors (80026 MB) Partition check: /dev/scsi/host0/bus0/target0/lun0
In order to use a multislot card reader, you must add the following parameter to the scsi_mod in the file /jffs/etc/modules.d/60-usb-storage:
scsi_mod max_scsi_luns=8
Usage
Mounting
mount /dev/scsi/host0/bus0/target0/lun0/part1 /mnt
Listing Contents
ls -l /mnt
You can also add the above line to /jffs/etc/config/usb.startup to mount the partition on reboot
# multiple partitions mkdir /tmp/usb/1 mount /dev/scsi/host0/bus0/target0/lun0/part1 /tmp/usb/1 # list its contents ls -l /tmp/usb/1 # second partition mkdir /tmp/usb/2 mount /dev/scsi/host0/bus0/target0/lun0/part2 /tmp/usb/2 # list its contents ls -l /tmp/usb/2
