Can't mount usb flash disk?

ak-87 · 05-17-2007, 01:55 AM

It's Slackware 11 with custom 2.6.21.1 kernel. My udev is hanging up my system, so I turned it off. I managed to mount usb flash disk for the first time with next command:

Code:

#mount -t vfat /dev/sdb1 /mnt/flash

After that I can't mount it anymore. As I wrote my udev is making problems, so I'm loading usb-storage and ehci-hcd modules on boot. When I type same command, this is what I get:

Code:

#mount -t vfat /dev/sdb1 /mnt/flash
mount: special device /dev/sdb1 does not exist

I checked /dev but there is no sdb1 node, although my dmesg shows this:

Code:

Initializing USB Mass Storage driver...

Also lsusb output:

As I said I mounted it for the first time in exactly same way, but now it is not working. Any ideas?

I don't know. It should work manually. What version of usb controller do you have (1.0, 1.1, 2.0). If lower than 2.0 try uhci/ohci instead.

Try activating hotplug. Maybe it will find something.

ak-87 · 05-17-2007, 03:16 AM

Hotplug also hangs system. I've upgraded udev with package from Slackware-current and it works now just fine. Now I can mount usb flash without any problems.

Thanks anyway!

Alien_Hominid · 05-17-2007, 03:27 AM

But it should work manually. Udev is not a magic. But that's ok if you have it working.

ak-87 · 05-17-2007, 03:52 AM

I don't want to open new topic, but after upgrading udev I get next messages on boot:

It's a chance that you will need to upgrade more packages. Maybe something is said in changelog.

H_TeXMeX_H · 05-17-2007, 11:39 AM

udev and hotplug should not be hanging your system. I think you may have made a mistake when compiling the kernel. Try the kernel compile guide and slackbook (in my sig).

How did you compile it ?

Udev and hotplug hanged my system (it is Toshiba Satellite A100-153; check this link's Installation section http://home.comcast.net/~fbui/Linux-on-ToshibaA105.html) before custom kernel (on test26.s - 2.6.18), so I don't think that custom kernel is problem. Right now udev, after upgrade from Slackware-current, is working fine (except those error messages on boot, above) and hotplug service is off.

I compiled my custom kernel like this:

#make mrproper
#make xconfig
#make bzImage && make modules && make modules_install
#cp arch/i386/boot/bzImage /boot/vmlinuz-2.6.21
#cp System.map /boot/System.map-2.6.21
#ln -s /boot/vmlinuz-2.6.21 /boot/vmlinuz
#ln -s /boot/System.map-2.6.21 /boot/System.map
#lilo
#reboot

H_TeXMeX_H · 05-17-2007, 12:57 PM

Oh, I see. Then I'm not sure. Maybe try upgrading to Slackware -current.

ak-87 · 05-17-2007, 01:30 PM

I would love to, but I am still using dial-up.

rworkman · 05-17-2007, 04:00 PM

The udev package from -current expects different rule syntax and different location of starting udevd in the init scripts. If you're going to use packages from -current, you need to do a full upgrade to -current.
As to why it's not working on 11.0 with stock 11.0 udev package, it's likely a kernel config problem. Reproduce the issue with the stock 2.6.17.13 kernel from /extra on 11.0 and we'll go from there.

This is what happens with stock 11.0 kernel and udev package on boot:

Code:

cs: IO port probe 0xc00-0xcff : clean
cs: IO port probe 0x820-0x8ff : clean
cs: IO port probe 0x800-0x80f  <-- hangs on this line

Maybe try this:

Blacklist 'ahci' or remove it from kernel.

bassmadrigal · 05-19-2007, 05:42 AM

do

Code:

ls -la /dev/sd*

and paste the output.

It could be udev is assigning it a different device name. My usb drive changes occasionally.
