how to detect USB devices like MP3 players
I'm trying to connect my sansa e250 to my computer but I don't know where to find it in the options.
if someone could help me I would appreciate it a lot |
Usually it will get mounted automatically under a certain directory. What distribution (Suse, ubuntu, pclinux os, etc) are you using? And what desktop (KDE, gnome, xfce, etc)? That'll help a bit more.

USB devices
i am using ubuntu and gnome for a desktop
|
I think in Gnome, you use Nautilis. The device should get mounted someplace like /media/sda1 or the like.
|
i went to computer and then i went to file system all i see in media is cdrom and cdrom0
|
In Ubuntu terminal type
Code:
sudo su To mount it manually, assuming sda1 is needed Code:
mkdir /media/sda1 |
i tried to mount it but when the sda1 folder comes up in media i clicked it and it just brought me back to the file system menu
|
you can see if it is being recognized when you connect it with:
Code:
$ lshal -h Code:
$ dmesg | tail -n 20 If it doesn't get mounted automatically, you can mount it with Code:
$ pmount [device] |
Quote:
Because in your case sda1 is obviously the root file system. That's why you should check dmesg or look for it in "$ fdisk -l" btw... you usually don't have to be root to see removable devices with "fdisk -l"... and you certainly don't have to become root permanently "sudo su"... As root there are so many ways to do permanent damage just with typos. |
I have left in Post #6 this line
Code:
ls /mnt/sda1 If Ubuntu disallows you to see it then you don't have owner permission to access the files. To change it you need to type this line in the "root" terminal Code:
chown -R your_username /mnt/sda1/* |
this is what it shows me:

wait 15 seconds and try again... (you did this right after you connected, right? ) This should show up almost instantly though.
If not, post the output of "fdisk -l" and "sudo fdisk - l" if the first one returned nothing. |
well now it tells me this:
josh@josh-laptop:~$ dmesg | tail -n 20 [ 87.020000] ACPI: PCI Interrupt 0000:00:02.0[A] -> GSI 16 (level, low) -> IRQ 17 [ 87.020000] [drm] Initialized i915 1.6.0 20060119 on minor 0 [ 87.504000] ppdev: user-space parallel port driver [ 88.360000] apm: BIOS not found.

hmmm...
What it should say is "blah blah attached removeable device [dev] blah blah" But it doesn't... Well... check fdisk. this is odd though. Quote:
Code:
$ sudo chown user:group [mountopoint] Another way to do this would be by mounting it directly with user permissions... If pmount doesn't work... Well I'll get to that IF pmount doesn't work :) |

Apparently the problem is that the mp3 player is in MTB-mode, and you have to switch it to MSC-mode -- looks like you have to adjust that on the player. Quote:
