mounting usb stick problem, no sdb1

[luca]

Hi all

For a while I'm trying to mount my usb stick, which only works fine when it is already plugged in at boot time. If this is not the case, no sdb1 (sda1 is already in use for something else) is created after plugging it into one of the other usb-slots...

Does anyone know what I've missed during configuring my kernel (2.6.3)
I've also niticed that I cant select 'SCSI device support', there are ---- at the beginnig of that??!!

thanks in advance
Luca

If it works when it's plugged in at boot, it's not a kernel problem, unless modules arn't loading, but get to that later.

Are you using udev or devfs? have you installed hotplug? is it working?

try doing 'tail -f -n25 /var/log/messages' as root and then plugging in the stick. or just looking at tty12 and plugging in the stick, i.e. what is syslog saying?

whats on /dev/sda? that the stick is being sdb?

If your using udev, ls /dev before and ~30secs after plugging in the stuck.

That should give us somewhere to start, a link to your /usr/src/linux/.config can't hurt either, along with kernel version.

this is the message I get when I connect the usb-stick:

after this the sdb (not sdb1) is created...
there is also nothing created in /dev/scsi/host1/bus0/target0/

My .config file is at http://www.phys.uu.nl/~calje/gentoo/.config
and my kernel version is 2.6.5 (just upgraded)

I use devfs

here are all modules that I've loaded:

bhw024 init.d # lsmod

No idea how to look at tty12 or what syslog is saying

Hope this will help to solve the problem

Thanks

there is no security switch on my usb-stick
And mounting sg1 didn't work, get a message that it is not a block device

But what about hotplugging, there is something in my kernel and in my /etc/init.d, are these doing the same thing and should I choose only one of them??

And what about the ohci_hcd, uhci_hcd and ehci_hcd is there no conflict between them???

Luca

You need the stuff in the kernel, thats the drivers, you also need the stuff in /etc/init.d, thats the software that does stuff with the drivers. Is /etc/init.d/hotplug started?

try /etc/init.d/hotplug start

and then try again. If that works, do rc-update add hotplug default (you should probably do this anyway) to start hotplug on boot.

Here is something else, when I start /etc/init.d/usbd

bhw024 init.d # ./usbd start

When plug my usb-stich in, this deamon show an other
FATAL: Module usb_scsi not found
how do I get this module

adding hotplug was not a succes, somehow nothing showed up during boot an no X too

Hmm...I seem to be at my limit now, all I can suggest is doing make menuconfig again, and looking for more usb/scsi modules.

Have you ever tried to mount it manually as root
#mount -t vfat /dev/sdb1 /mnt/blabla
it gives me an error like couldn't mount /dev/sd1 does not exist

but after this manual mount the device /dev/hdb1 or /dev/hda1 is created and you can mount it in your normal way
not the solution but an workaround
cu

[luca]

he thats funny
Here is what I did (think it's a little bit different than above suggested)

mount -t vfat /dev/sdb /mnt/usbstick

after this (which returns an error) sdb1 is created

so now I can mount it, mount -t vfat /dev/sdb1 /mnt/usbstick

This is nice, but not the end (for me)!!!!!!

thanks Luca

[Nate_S]

It sounds like the module may not be getting loaded right the first time? you could try

rmmod usb-storage
modprobe usb-storage
mount -t vfat /dev/sdb1 /mnt/usb

or something like that

Another thought is your stick might be one of the usb devices that needs the 'probe multiple LUNs' selected in the kernel, so see if that makes any difference.

Good luck,
Nate

[luca]

Those LUNs were already enabled (I also disabled them, without succes)...
Also the rmmod usb-storage and modprobe....didn't work

But below is some output from dmesg after I plugged my stick in:

Hi All
I've written a small script that does the trick for me. Now I can mount my usb-stick easily without any problems. You can download it here: http://www.phys.uu.nl/~calje/gentoo

Good luck
Luca
