Slack 11 : Doesn't detect USB devices & can't shutdown ??

mnemonix · 12-15-2006, 10:38 PM

Recently, I installed Slackware 11, and then found 2 problems.

1. It doesn't detect my USB devices (external HD,memory card reader,etc)
2. Every time I try to shutdown, it always stuck at 'Power down',
unless I hit the power button.

Any suggestion ?
Thanks in advance

You might try to install kernel 2.6.x
That will solve most of your problems with hardware detection and also ACPI problems

Welcome to LQ!

Why do you say "It doesn't detect my USB devices (external HD,memory card reader,etc)"? How are you trying to detect them? Sorry, but you have one post and we have no clue as to your Linux knowledge.

From a terminal/konsole as root type "lsusb" and post the output here.

To make the computer turn off, you need some form of power management. The easiest thing to do is open a terminal, login as root, and in the file "/etc/rc.d/rc.modules" uncomment (remove the # in front of)

Code:

#/sbin/modprobe apm

If you're not familiar with Linux, use pico to edit that file; as it's more intuitive than other editors. Once you are logged in as root type "pico /etc/rc.d/rc.modules" without the quotes and then instructions are at the bottom of the screen.

Next you will need to edit "/etc/lilo.conf" and add

Code:

append ="apm=power-off"

after the line which reads

Code:

# Start LILO global section

After making changes to /etc/lilo.conf you must run "lilo" as root to write the changes.

If your using a kernel with ACPI you may need to add acpi=noirq to lilo.conf. If you get a lot of stuff about conflicting IRQs and an error on shutdown this might be your problem.

Sorry, I mean automounting.
I don't see something new at /dev/mnt

When it says power down, thats when you hit the power button. there is a way to make it shut down auto, but that requires editing a config file somewhere........... ?????

Slackware by default does not do automounting. You have to recompile
the kernel, etc. for that. I am able to plug in a USB device and have
Konqueror mount it and open it's location simply by clicking on the
Removable Device icon under Storage Media, but that is not the same as
automounting.

Until you figure out automounting, you can put this in /etc/fstab:

Code:

/dev/sdb1        /usb1            vfat        noauto,users,rw,umask=1000  0  0
/dev/sdc1        /usb2            vfat        noauto,users,rw,umask=1000  0  0

(substitute /dev/sdb1 and /dev/sdc1 for your first two devices)
for your USB devices. You also need to create the /usb1 and /usb2 mount
points, then change the owner to your normal user by issuing:

Code:

chown mingdao.users /usb1

(substitute your username for mingdao)
and change the permissions to your liking. I use:

Code:

chmod 757 /usb1

because I'm the only one using this box, and I want full read/write
perms on my devices.

This Quick and Dirty Guide to Linux File Permissions in LQ's Linux Tutorials is very good.

And afaik Slackware doesn't use /dev/mnt:

Code:

mingdao@silas:~$ mount /usb1
mingdao@silas:~$ ls -lh /dev/mnt
/bin/ls: /dev/mnt: No such file or directory

It doesn't on my boxen.
