Hello everyone

I have a problem mounting a USB key on an ASUS wl500g premium running on Kamikaze 8.09. The device is recognized by the router as it is shown below :

hub.c: new USB device 01:03.2-1, assigned address 2
scsi0 : SCSI emulation for USB Mass Storage devices

However, I cannot mount it since it doesn't seem to found the device it detected a few seconds ago :

root@OpenWrt:~# mount -t vfat /dev/scsi/host0/bus0/target0/lun0/part1  /mnt/
mount: mounting /dev/scsi/host0/bus0/target0/lun0/part1 on /mnt/ failed: No such device
root@OpenWrt:~# mount -t vfat /dev/scsi/host0/bus0/target0/lun1/part1  /mnt/
mount: mounting /dev/scsi/host0/bus0/target0/lun1/part1 on /mnt/ failed: No such device

Here are the packages installed. I checked them and I don't seem to miss an important one :

The usb key cannot be the cause of the problem, since I detect it on the same router running on White Russian 0.9.
I thought it could be the format type, but I can assure it has been formatted as fat, and it is confirmed when running with the white russian machine.

The re-installation of the firwmare on the asus didn't change anything. I'm seriously out of solutions and I begin to fear it is just a small mistake I would have missed.
I didn't find anything related on the forum.
Does anybody have any idea?

Thank you in advance.

The magic for me came with
opkg install kmod-nls-cp437 kmod-nls-iso8859-1

If that doesn't work provide output from lsusb (opkg install usbutils).

Than you for your answer. Unfortunately, installing those 2 packages didn't change anything, I get the same message when I try to mount the stick.

Lsusb provides me with this :

root@OpenWrt:~# lsusb
Bus 004 Device 001: ID 0000:0000
Bus 004 Device 003: ID 13fe:1e21 Kingston Technology Company Inc.
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

Which seems to prove the device is recognized by the router.

I also tried with other usb keys, but I got the same results.

This worked for me just now with an NSLU2 (ixp4xx).  I flashed the stock image (dated 15 Feb) from here:

http://downloads.openwrt.org/kamikaze/8 … uashfs.bin

I did "opkg update" and "opkg install kmod-usb-storage kmod-fs-vfat kmod-usb2"

I actually did those one at a time and only after the kmod-usb2 did I get an "sda: sda1" from dmesg.  But no drive mounted.  I rebooted and got the dmesg message, "FAT: codepage cp437 not found".  I did

opkg install kmod-nls-cp437

I got the dmesg message, "FAT: codepage iso8859-1 not found".  I did

opkg install kmod-nls-iso8859-1

There were then no dmesg errors, and df gave me

/dev/sda1             15642560   2150432  13492128  14% /mnt/usbdrive

"ls /mnt/usbdrive" showed my files.

Thank you for your advices. As you can see in my log, there is no ask for any missing package. I tried to install the packages you mentionned (cp437 and kmod-nls-iso8859-1), but that didn't change anything. Am I suposed to load a module after installing those?

Anyway, mounting a usb key is not a priority as I can tranfer files through ftp. Thanks for your help though.

The discussion might have continued from here.
