Hallo,
I have upgraded to kamikaze yesterday, an all goes fine. I'm using Kamikaze with 2.4 kernel due to wireless issue(have anybody a news about 2.6 kernel availability with broadcom stable WiFi driver ?)

I have configured some packages to use /opt destination, which is a USB external harddisk. it works fine, but...
after restart,  sometime the USB disk is not detected and not mounted. When i unplug it manually and then plug in back, disk is back and abvailable on the /dev/scsi/......../disk(part1) path and can be mounted. All appropriate USB modules are loaded when i try lsmod...

Have anbybody an idea, what's wrong with boot sequence? Because my http server is installed on /opt USB disk, i need to start it immediately after restart, without a manual action.

Thank you very much for your hints and help.

Hmm, seems to nobody has idea how to solve the problem....

And if you rmmod / insmod rather then physically disconnect?

I'm using kamikaze 7.07 (brcm47xx-2.6) firmware on ASUS WL-500Gp, but i can't mount USB devices.

What's the problem?

Do you, at any time, instruct Linux to mount the disk? OpenWRT has, to my knowledge, no 'automount' function. So put an entry in your fstab and add a mount command in the custom startup file.

Of course i tried, this is my problem, i don't know what parameters need mount. In http://wiki.openwrt.org/UsbStorageHowto?highlight=(usb) is many mount command with parameters, like:

mount /dev/scsi/host0/bus0/target0/lun0/part1 /mnt

But in my system /dev/scsi don't exists.

And in White Russian not need mount command, it "automounts" every USB devices.

That path is supposed to be the path to your HD/USB stick. It may vary, but it always is under /dev/scsi afaik. So if it's not there, that means it is not recognised.

Im having the exact same problem.....its driving me insane....

EDIT: this is more confusing

root@ZPM:/dev# fdisk -l

EUREKA

Ive got some good news kids!

you actually *gasp* have to mount your drives....i know

so what i did was, using a usb drive that i had prepared eariler

swapon /dev/sda1

that fixed my swap......

then from the /mnt directory

mkdir store
mkdir sml
mount /dev/sda2 /mnt/sml
mount /dev/sda3 /mnt/store

yous gotz yo data

microphone!

I tried your suggestions:

root@LaySoft:~# fdisk -l

Disk /dev/sda: 2029 MB, 2029518848 bytes
17 heads, 32 sectors/track, 7286 cylinders
Units = cylinders of 544 * 512 = 278528 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        7287     1981936    b  W95 FAT32
root@LaySoft:~# mount /dev/sda1 /mnt
mount: mounting /dev/sda1 on /mnt failed
root@LaySoft:~# mount /dev/sda /mnt
mount: mounting /dev/sda on /mnt failed
root@LaySoft:~#

Don't works. Which package containts swapon command?

LaySoft:
Based on the dmesg output you posted earlier, I think your USB disk is sde rather than sda, so you will need to adjust the device paths appropriately. It will also depend on what partitions exist on your USB disk.

fdisk will let you view and edit the partitions on the disk.

create a folder in /mnt and the try and mount to that instead of just /mnt....

swapon is built in i think ??? if you use it on a destination that has been formatted as swap it should work...

....i have just installed dd-wrt so i cant test it......i'll reflash back to kam and let you know what happens...

My linux guru friend solved the problem:

Need to install kmod-nls-cp437 and kmod-nls-iso8859-1 packages, and everything works now.

what are those packages for? you know for the sake of wrapping up the thread
