Topic: USB Storage Module

[hasan]

Hello All,
          Recently I removed usb-storage drives on some machines in my network using the code 

Code: [Select]

ls /lib/modules/$(uname -r)/kernel/drivers/usb/storage/usb-storage.ko
mv /lib/modules/$(uname -r)/kernel/drivers/usb/storage/usb-storage.ko /root
Now I want to re-enable usb on these machines, so I copied back the usb-storage.ko from /root to the /lib/modules/$(uname -r)/kernel/drivers/usb/storage, but its not working and I do not knwo what to do.

Is there any way I can reinstall the driver.

Please help

Regards
Hasan

Why would you do such a thing? You probably need to reload the drivers, perhaps this might work:

Code: [Select]

depmod -a
modprobe usb-storage
After that scroll trough the output of below command to see if it is loaded:

Code: [Select]

dmesg | more

Hello Cactus,
           I was trying to disable all the usb devices in the LAN and while searching on net I got the link http://www.cyberciti.biz/faq/linux-disable-modprobe-loading-of-usb-storage-driver/ .

But now I have to enable usb device on some machines which I don't have any clue of how to do.

Also appreciate your help, but it didn' work.

I got this message in the

dmesg | more

Code: [Select]

usb 1-7: new high speed USB device using ehci_hcd and address 3
usb 1-7: configuration #1 chosen from 1 choice
usb 1-7: New USB device found, idVendor=058f, idProduct=6387
usb 1-7: New USB device strings: Mfr=1, Product=2, SerialNumber=3

Not? How are you reading below information then?

dmesg | more

Code: [Select]

usb 1-7: new high speed USB device using ehci_hcd and address 3

AFAIK that is the detection of a USB mass storage device.

Hello Cactus,
             Yeah thats the whole problem, dmesg is showing it but when I am doing fdisk -l
it is not detected

Code: [Select]

[root@hasan ~]# /sbin/fdisk  -l

Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

[root@hasan ~]#
/dev/sda is my hard drive.

the usb is missing ...


Don't know wat to do

Don't know wat to do

Most likely the drive is not automatically mounted. I think you will find some clues here: http://wiki.contribs.org/USBDisks

[hasan]

Thanks Cactus for the link,
              but it didn't help as the information regarding enabling of usbs is not present.

Thanks Cactus for the link,
              but it didn't help as the information regarding enabling of usbs is not present.

I told you you already have your drivers loaded, otherwise your drive would not be detected.
Now you need to configure your server to mount your drive, this information is in the link I provided you, especially the sections on identifying your drive should get you running.

AFAIK that is the detection of a USB mass storage device.

That's the detection of the usb device. That doesn't show loading of the usb-storage module, or registration of the new device with that module.

If Hasan hasn't rebooted, I'd at least recommend doing that. I'd also recommend:

rpm -V kernel kernel-smp

          Recently I removed usb-storage drives on some machines in my network

Please promise that you won't do that again.

[hasan]

Hi Charlie,
      Thanks for the help and suggestions.
I rebooted my machine, and wen I do
rpm -V kernel kernel-smp
I get the following output

Code: [Select]

package kernel-smp is not installed

so though the machine is detecting the usb but still its not loading it

Thanks and Regards

this is  not SME's kernel.. why are you using fc10 one?

Stefano

[hasan]

Hey Stefano ,
             I am using FC10 in my LAN and using sme as my server.

So this problem of usb occurred on my LAN and not in on my SME.

ops.. I didn't see we are in "general discussion"

anyway, you should ask in fedora's forum, even if Charlie's and Cactus' advices are good..

I had not noticed either and was assuming we were on SME Server as well... but hey it is linux
