USB devices doesn't appear

deepix · 2010-01-27 21:46:34

Hi

I've installed arch in the last few days, everything is almost fine.
The only problem is about the usb devices (like my pen and mobile modem). The system finds them, but they doesn't appear in /dev/sdX

lsusb shows me that the usb is there, but nothing else happens.

dmesg shows me this:

usb 2-2: new high speed USB device using ehci_hcd and address 2
usb 2-2: configuration #1 chosen from 1 choice
Initializing USB Mass Storage driver...
scsi2 : SCSI emulation for USB Mass Storage devices
usbcore: registered new interface driver usb-storage
USB Mass Storage support registered.
usb-storage: device found at 2
usb-storage: waiting for device to settle before scanning
usbcore: deregistering interface driver usb-storage

lsmod | grep usb

btusb 9768 0
bluetooth 44621 1 btusb
usbserial 27170 0
usbcore 118921 6 uvcvideo,btusb,uhci_hcd,ehci_hcd,usbserial

My user is in storage group.

And i can mount CD and DVD.

If anything else is needed i will post here.

Can anyone help me?

thnaks

What wm are you using?

Did you install hal?

EDIT: Maybe I should read the post more careful before replying Didn't notice about you being able to mount dvds.

Welcome to the forums deepix.

How are you starting Openbox?

if you run

udevadm info

in a terminal and then insert a usb drive, what is displayed?

I just tried on my computer, and I got the following:

[rene@ArchLounge ~]$ udevadm monitor
monitor will print the received events for:

Here says that
http://wiki.archlinux.org/index.php/HAL … _correctly

, and if you are able to manually mount the USB device in question,

I can't. But i will try anyway.

EDIT: doesn't work

Just checked my lsmod, and I have the following modules loaded

usbcore    140421  8 usb_storage,usbhid,uvcvideo,snd_usb_audio,snd_usb_lib,ohci_hcd,ehci_hcd
scsi_mod    92676  5 usb_storage,sg,sr_mod,sd_mod,libata

Don't know if that could make the difference.

Did you check the hal policy like suggested in the wiki?

Yes i check the wiki link you post, but nothing changed

usbserial              27170  0 
usbcore               118921  6 uvcvideo,btusb,uhci_hcd,ehci_hcd,usbserial
scsi_mod               78933  4 sg,sr_mod,sd_mod,libata

How can i have "more" modules loaded? i've put them in the rc.conf, but they don't load (i think i don't have them).

madeye · 2010-01-27 23:37:36

Do you have the possibility to check the USB drive in another computer? Just to make sure there are partitions defined?
I know. A pretty long shot, but I am running out of ideas...

EDIT: It looks like udev is loading the usb_storage module when needed on you setup.

I have Mint 8 and Windows 7, and works just fine.

You have more modules loading

usbcore    140421  8 usb_storage,usbhid,uvcvideo,snd_usb_audio,snd_usb_lib,ohci_hcd,ehci_hcd
scsi_mod    92676  5 usb_storage,sg,sr_mod,sd_mod,libata

scsi_mod               78933  4 sg,sr_mod,sd_mod,libata

I don't have the "usb_storage","usbhid"...

This from your first post looks wrong:

usbcore: deregistering interface driver usb-storage

Try 'modprobe usb-storage' and then insert the memory stick again, checking dmesg.

Doesn't change anything

The output is the same

The module is not loading because "lsmod" doesn't change too.

grey · 2010-01-28 02:15:06

Can you run with verbose mode? E.g.

[root]# modprobe -r -v usb-storage
rmmod /lib/modules/2.6.32-ARCH/kernel/drivers/usb/storage/usb-storage.ko
[root]# modprobe -v usb-storage
insmod /lib/modules/2.6.32-ARCH/kernel/drivers/usb/storage/usb-storage.ko

deepix · 2010-01-28 09:37:41

Thr first one doesn't return anything

[root@arch-book ~]# modprobe -r -v usb-storage
[root@arch-book ~]# modprobe -v usb-storage

In my case neither the root has access to removable disks

but only root can access removable media that is inserted

I've changed the hal.conf, but no luck so far.
I've tried to login as root after booting up the computer, then i pulg the usb but /dev/sdX doesn't appear.

That's not a problem of mounting devices, i think it's related with modules loading

JackH79 · 2010-01-28 10:25:55

Shoot me if I'm wrong, but I fixed that problem on my machine with udev rules http://wiki.archlinux.org/index.php/Ude … SB_devices a while back.

However, the wiki says, that it's outdated, so therefore: maybe my advice is too!

deepix · 2010-01-28 12:02:32

I think the problem isn't related with mounting, because for monting i need to have a "file" in dev folder.

My HDD is sda, and partitions are sda1, sda2 ...
And this files appear in the /dev folder (for example /dev/sda1)

But when i plug the usb stick, it doesn't even appear a "file" (probably it would be "sdb") in the /dev folder.
(no file)=(no mounting)

I'm a noob at linux, and if i'm saying anything wrong sorry

EDIT: I've installed USBView, and when i open it as root (or normal user) returns me an error:

Can not open the file /proc/bus/usb/devices

Verify that you have USB compiled into your kernel, have the USB core modules loaded, and have the usbdevfs filesystem mounted.

What kind of file-system does have the partition on your pendrive? Try to format it on ext2/ext3 and see if it works.

I've tried with ntfs, and now with ext3. Nothing changes.

I get the same error with usbview. I don't think your problem lies here. I think you're right that a module is not loaded correctly.

If I run dmesg | grep usb after inserting a USB drive, I get the following

usb 1-1: new high speed USB device using ehci_hcd and address 5
usb 1-1: configuration #1 chosen from 1 choice
usbcore: registered new interface driver usb-storage
usb-storage: device found at 5
usb-storage: waiting for device to settle before scanning
usb-storage: device scan complete

Compared to what you wrote in the first post it seems like the drive is never scanned. And that's probably why you have no /dev entry.
The usb_storage driver is loaded and unloaded automatically in your setup (the line usbcore: registered new interface driver usb-storage). But somehow it is unloaded only moments later. (the line usbcore: deregistering interface driver usb-storage.

Does lsmod | grep usb before and after you insert a usb drive look the same?
Mine changes the last number on the usb_storage line from 0 to 1.

grey · 2010-01-28 16:10:03

If you do lsmod immediately after inserting the usb-storage module via modprobe, is it listed?

I don't have the module usb_storage (this module has never loaded)

But nothing has changed before and after i plug the usb-stick, the lsmod is the same.

I do

[root@arch-book ~]# modprobe -v usb-storage
insmod /lib/modules/2.6.32-ARCH/kernel/drivers/usb/storage/usb-storage.ko

but

[root@arch-book ~]# lsmod | grep usb
