1) find out what device it is (dmesg | tail), let's assume sda1
2) mount /dev/sda1

When i tip:

tc@box:~$ sudo mount /dev/sda1 /mnt/usb
mount: /dev/sda1 is not a valid block device

and  

tc@box:~$ sudo fdisk -l

Disk /dev/hda: 255 MB, 255328256 bytes
8 heads, 61 sectors/track, 1021 cylinders
Units = cylinders of 488 * 512 = 249856 bytes

   Device Boot      Start         End      Blocks  Id System
/dev/hda1   *           1           5        1189+  b Win95 FAT32
/dev/hda2               6          10        1220  83 Linux
/dev/hda3

but not find the usb device.

and ->

tc@box:~$ dmesg | tail

try to see which other block devices are connected by looking at /sys/block - you shoud find the hda directory for you harddrive, and another one for the usb device.

you can also try running blkid and post here the output.

Try following commands in a terminal window and post output:

Quote

fdisk -l /dev/sda
fdisk -l /dev/sdb

This would help to identify issues caused by wrong partitioning and/or file system types.

Could you be more specific what your "device storage usb" exactly is?

Are you sure same PC has a 255MB hdd and has also a USB port?

What/where is loop3 ?
 

Code: [Select]

losetup /dev/loop3

is a 2 GB USB memory

What/where is loop3 ?

tc@box:~$ losetup /dev/loop3
/dev/loop3: [0303]:5986 (/mnt/hda3/tce/libusb.tcz)

As you happen to have libusb installed, do you also happen to have usb-utils installed?
If so, you could:

Code: [Select]

sudo lsusb

On a sidenote: the output of fdisk for your /dev/hda looks a bit strange to me...

Post by: jjreina on August 02, 2010, 05:36:01 AM

Sorry but i am very noob whit linux and tc me only worked with Ubuntu :'(

tc@box:$ sudo lsusb
lsusb: error while loading shared libraries: libusb-0.1.so.4: cannot open shared object file: No such file or directory

Title: Re: mount usb
Post by: tinypoodle on August 02, 2010, 05:40:48 AM

Hmm, missing lib is in libusb, which losetup shows to be present...

try

Code: [Select]

dmesg |grep -i usb


Title: Re: mount usb
Post by: jjreina on August 02, 2010, 05:44:40 AM

tc@box:~$ dmesg |grep -i usb

*cough*

It doesn't make sense to use a bootparam "nousb" and then expecting usb to work...  :o

Title: Re: mount usb
Post by: jjreina on August 02, 2010, 05:55:17 AM

Sorry, but I got the boot file with parameters set and did not tell me anything.

Try to change it.

Thank you very much and sorry for the inconvenience.

Ok, edit boot file and i could mount usb not problem.

Thanks
