MP3 player doesn't mount.

[breem42]

Running Hardy Heron Kubuntu, fully updated. I have a Panasonic SV-MP20V that does not seem to mount. I looked at this discussion: this discussion but I have the problem described by idr, i.e. when I type

sudo rmmod ehci_hcd
password: <password>

I get

'ERROR: Module ehci_hcd does not exist in /proc/modules'.

Typing

sudo modprobe ehci_hcd

allows the rmmod command to work without the error message (not that I know why, but it does). But it does not fix the mount problem.

Here is my lsusb:

Bus 003 Device 001: ID 0000:0000  
Bus 002 Device 005: ID 04da:3701 Panasonic (Matsushita) 
Bus 002 Device 002: ID 04b4:0001 Cypress Semiconductor Corp. Mouse
Bus 002 Device 001: ID 0000:0000  
Bus 001 Device 001: ID 0000:0000

which suggests that the player can be seen.

When I type the following:

dmesg > dmesg.log
grep usb dmesg.log

I get

I suspect the above is the result of my monkeying about plugging and unplugging the player.

This is a device that has mounted successfully under Win2k, WinXP, and even an old install of Linux (can't remember which -- may have been an old computer). I could just keep booting WinXP to get at the recordings I make on this device, but would rather not.

Thanks in advance to anyone who can help.

This will happen if you unplug the device without unmounting it first.

What yoyoned means is that you probably mounted it into Windows and removed without unmounting it. This can cause problems when trying to mount in Ubuntu, such as you're having.

It appears the module has already been removed.
It is possible windows has not release its lock on the usb device, if you can try connecting it to a windows machine and then click 'safely remove device' from the taskbar. If this does not work try:

sudo mkdir /media/mp3device

sudo mount /dev/sdb1 /media/mp3device
or
sudo mount -t vfat /dev/sdb1 /media/mp3device

Replace sdb1 with you device, if you are not sure what to replace it with post the output of

sudo fdisk -l

If this fails can you post the out put from the mount command, if it works

nautilus /media/mp3device

should open you device

Thank you to all who replied.

I followed your directions (mounting under XP then unmounting. It did not automount under Ubuntu, but the "sudo mount" command did work although I don't get an icon on my kubuntu desktop. Now I'm going to look elsewhere on this site to see how I can get it to automount.

I'll post here with my results.

[breem42]

Well that was frustrating. There seem to be many people with various devices that have my problem, but none with a solution (unless there is something I've missed). Yes you can make a usb drive mount automatically on boot (or is that login), but that is not going to be my situation usually.

Just to clarify: My system automounts properly for a 2GB Transcend pen drive, for a Sansa e250, and for a Sansa View 8GB (i.e. the icon appears on my desktop and the drive appears under "/media" when I plug it in). Just not my Panasonic SV-MP20V.

I guess I can make a little script to mount it, and another to unmount, but that requires sudo/gksudo and hence typing in a password. But I suspect that perhaps there a table somewhere that I can edit to add this to the usb drives that the system recognizes, something like fstab.

Any hints?

[tarps87]

Could you post the output of this command please

gnome-mount -vbd /dev/sdb1

This will pipe the output to a file if it makes it any easier

gnome-mount -vbd /dev/sdb1 > output.txt

Hardy has known issues with mounting some MP3 players, like the one sitting next to me If you have an Intrepid live CD, try it with that. If it mounts, then a good solution would be to upgrade to Intrepid.

I missed that, I thought the op was using Intrepid. It is possible I know what the cause is and how to fix it but the output from

gnome-mount -vbd /dev/sdb1

would confirm it.
Upgrading to Intrepid may not be a bad idea, most of the bugs in KDE4 have been worked out now, trying the live CD before installing/upgrading would be a good idea though.

Sorry it's taken so long to reply, and thanks for all the responses.

My device shows up as "sdc", so the mount command that works for me is:

sudo mount -t vfat /dev/sdc /media/mp3device

When I have device plugged in and not mounted, and I type:

gnome-mount -vbd /dev/sdc

I get a little window popping up with the message:

Unable to mount media.
There is probably no media in the drive.

In the command window line the response is

gnome-mount 0.8
** Message: Drive /dev/sdc does not contain media.

which, of course makes no sense, since the mount command works fine. Is "gnome-mount" a wrapper for "mount"?

BTW, when I use the "sudo mount ..." command, the files all have ownership of "root/root" (which I guess makes sense, since the command is executes as "root". But this means I cannot write to the drive.

Thanks again for your help.
