Connecting N900 mass storage mode linux

[shadow12]

Hi guys, having a small issues connecting the N900 to my Ubuntu install. When connected to the machine using mass storage mode. The device does not get mounted. looking at log/messages it reports seeing it as ehci_hcd

Dec 2 10:13:33 computer kernel: [1038738.136785] usb 1-5: new high speed USB device using ehci_hcd and address 11

Any ideas?

Thanks

[archebyte]

What version of Ubuntu are you using?

Karmic mounts it automatically as '/media/Nokia N900' when Mass Storage Mode is selected.

The N900 will not be mounted if files in the MyDocs are open or directories under MyDocs are 'cd' ed into in Xterm.

This held true for the N8x0 too :)

I dont think i have anything open. Tried straight after reboot as well. Maybe something weird with my ubuntu install. Although never had issues in the past.

Looks like Ubuntu does not even recognize the eMMC. Have you tried a different USB port?

Do you get the same result when the USB cable is connected after turning off the N900?

[shadow12]

OK tried all USB ports on PC (excessive I know) no luck.

Tried another ubuntu system at it seems to be working fine. So will try again on this machine after reboot. Can't reboot at the moment too much running.

Weird thing is it did not have all the folders that are listed in the N900 file manager. Is this normal?

It is if you had some programs running that were still accessing those directories, yes.

On the N900, not to my knowledge. It was after reboot. Unless there are apps I need to shutdown that start on startup? So I guess the directory structure I see on the N900 should be mirrored directly on the Linux machine? If yes I will have a poke around and see.

[shadow12]

OK rebooted my ubuntu system and it is all ok. The N900 and sdcard get mounted when on and when switched off the same. Still though the only folders I see are: cities, DCIM, Mac OS, tmp as well as autorun.inf

The hidden directories are renamed in the N900 File-manager.
.documents -> Documents
.sounds -> Audio Clips
.video -> Video Clips
.images -> Images
DCIM -> Camera

So in Ubuntu, view the hidden directories and you should be good to go. 'ls -la' or Ctrl+H in Nautilus.

[ewan]

Is it just me, or is that behaviour completely perverse and entirely unhelpful? What's the supposed upside of hiding the directories (using the unix convention) then making them visible again via Filemanager hacks?

Also - what happens if you just rename them so they're actually called their 'user visible' names?

[shadow12]

Excellent. Didn't think of that. Doh!!

Anyhow now I have your ear is there any way to mount smb shares on the N900 and vice a versa. Even just a point in the general direction of a solution would be good. Since with the meamo platform I dont know how much is applicable from previous versions.

I guess it stops people deleting them by accident?!?

IIRC, it is related to localization.

The File-Manager may take a dump. It should be worth trying it out :P

IIRC, smb shares are not supported out of the box. It requires loading some kernel modules. Search tmo - I recall reading a thread where this was discussed.

[Andre Klapper]

Yes - See https://bugs.maemo.org/show_bug.cgi?id=2905#c8 .

[shadow12]

Sorry bumping thread for something a bit more specific. Had a search. Found pages in wiki which relate to using older models but nothing N900 specific (Still not sure what is compatible and what is not). Found this:

https://garage.maemo.org/projects/wizard-mounter

would that work?

[shadow12]

Yes - See https://bugs.maemo.org/show_bug.cgi?id=2905#c8 .

Wow sounds like I might have opened a can of worms. Are there any 3rd party apps that offer simple mounting support that currently work on the N900? If not are there any projects which are nearly there but need some help?:D

IMHO mounting shares is crucial for a geek phone.

[shadow12]

Bump (if allowed)

[Fargus]

@OP - If you want to share information from a Windows machine to the N900 you could always go the other way and use Unix services support on Windows and see if that helps. Depends on what you are trying to achieve. If you can post a use case then we might be able to suggest something slightly different that accomplishes your aim.

[shadow12]

Thanks for replying in thread.

Well i have three machines. Each sharing certain things like printers and media files. I have them all done through samba since people I live with use windows and like access to those devices. All I want to do is access those shares with my N900 using the wireless network i have in my house. I can already ssh to all of them and that is fantastic but definitely would like share mounting abilities. Also would like to be able to come home mount my N900 share and simply copy files to and from it.

[Fargus]

Are you hosting the printer and other shares on a main desktop or everything directly to the router via wireless?

If you have a host machine running Linux then I suspect your easiest route at present would be to mount volumes on there and tunnel through.

UPnP is a potential option here, especially for windows i suspect.The easiest long term option would be a NAS device and rsync up to it.

If you need to go direct then have a look at progress on Wizard Mount.

Just an after thought, what about using a webserver for sharing too.

[shadow12]

Nope, everything is shared through pc's.

I will hold out for a while before I decide. Maybe I will look into wizard moutn.

Thanks for all the help guys.

[Laughing Man]

Hmm is there no way to use mass storage mode to sync with any mass storage mode supporting music player (doesn't seem to see the n900 at all).

Though I could just drag and drop like I normally do. :D Just thought I'd give it a shot.

[jamesrich]

I'm also having a problem connecting my N900 to my car's Dension Gateway 300, USB box.

Basically doesn't mount the mass storage memory.

I've also since tried with my Toshiba TV, where it crashes the TV, I've got to switch it off and back on to get the remote working.

Is their a fault with the implementation of USB mass storage?

[dalonso]

I tested yesterday coonecting the N900 as an usb storage device to my notebook running Karmic, and I'm sure there is something weird in the usb implementation.

At first try two N900 icons appear (there's no sd card in my N900). Sometimes, I cannot even browse any of the icons. Other times, one or the other of the two icons change their image to a "sheet of paper" becoming totally irresponsive and cannot even be opened in Nautilus.

Sometimes I have to unplug and replug in order to get one of the icons (the one with DCIM, Mac OS, ...). I was going crazy looking for MyDocs directory until a I learnt by reading this thread about the hidden directories.

With my N800 it works flawlessly.

Has someone reported a bug?

[sup]

If the device says it cannot be connected because it says it is in use and your /home/user/MyDocs cannot be unmounted and

lsof /home/user/MyDocs

gives you nothing (if it output something, that something would need to be stopped first), you can unmout it manually in terminal with:

umount -l /home/user/MyDocs

Took me two hours to learn this the other day.

Ubuntu, but I was talking about N900 itself.

[impeham]

Recently, i have a problem related to mass storage mode - after doing several tests i am able to reproduce this behavior every time:

After restart to the N900, i connect it in mass storage mode, and both mmc and mydocs becomes accessible from my pc.

after i disconnect from mass storage mode and reconnect again, only MyDocs is available and i get this message:

"Only device storage connected, Memory card already in use"

I am unable to access mmc card again in mass storage mode until i restart (it is accessible from the n900 after i disconnect mass storage and not accessible after it is connected again - so it seems that the mass storage mode actually dismounts the card, but still i cannot access it from the pc).

Anyone knows how to debug/fix this issue?

[sup]

Try the mount -l command on the mmc directory before trying to mount?

[impeham]

i'm not sure i understand what you mean.

-l is an option of umount - not mount, and the problem i'm having is not mounting the mmc, but dismounting it + recognizing it in mass storage mode from the PC.

If I understand it correctly, yo ucan always access the mmc card from N900, but from PC only after a reboot, right? If so, try manually unmount (with umount -l) the mmc card before you try to connect it to a pc after second time.

If it is inaccesible from the PC, it probably means it is still mounted somehow on N900.

[Zas]

Maybe something is accessing the memory card.
Try "lsof | grep mmc1" and "ls -lR /proc/ | grep mmc1> tmp;clear; cat tmp;rm tmp"

[misterc]

Maybe something is accessing the memory card.
Try "lsof | grep mmc1" and "ls -lR /proc/ | grep mmc1> tmp;clear; cat tmp;rm tmp"


lsof /dev/media/

[impeham]

Before connecting the usb cable and activating mass storage mode:
"lsof | grep mmc1" returns empty

Output of:
"ls -lR /proc/ | grep mmc1> tmp;clear; cat tmp;rm tmp" is empty also:

/proc/irq/86/mmc1:
[root ~]#

Output of:
"lsof /dev/media/" is "lsof: status error on /dev/media: No such file or directory"

Also, as I described in post #31 - after connecting the cable and activating mass storage mode, I can see that there are no files in /media/mmc1(and I also get the error mentioned "Only device storage connected, Memory card already in use")

if I disconnect the cable, I can see the card files again in /media/mmc, which I think shows that the mount/dismount worked correctly by mass storage mode.

I can also freely mount and umount mmc using the following with no errors (which causes the files in /media/mmc1 to be accessible/inaccessible):

mount /dev/mmcblk1p1 /media/mmc1
umount -f -l /media/mmc1

[nman]

Are you "safely removing" the n900 from your host PC? I sometimes get this problem if I don't.

You can also try running
sudo /usr/sbin/osso-usb-mass-storage-disable.sh
and connect to pc again.

[Estel]

I don't know if it's useful info for current on-topic problem, but I got different "unknown" behavior - after successfully connecting device in mass storage once, (and removing safely), MyDocs isn't accesible for device. No big deal - I've created script that mount it again after disconnect. Furthermore, while being connected, MMC (microSD) is accessible for *both* desktop and N900 (that is, mounted simultaneously).

I can connect it again to desktop PC, yet, only for limited amount of time. After few hours (wasn't able to detect it precisely), connecting device result in charging only - HUBS with diode lighting up doesn't show any device connected, desktop OS'es doesn't act like seeing anything, etc. I've tried many tricks with osso-usb-mass-storage-enable.sh etc, to no avail. Only restart fix this problem.

I'm perfectly sure, that nothing is accessing it, also, it isn't mounting problem - device isn't recognized as USB gadget at all.

Safely removing the device does not help - same issue.

/usr/sbin/osso-usb-mass-storage-disable.sh does not help also...

[retsaw]

Maybe something is accessing the memory card.
Try [...] and "ls -lR /proc/ | grep mmc1> tmp;clear; cat tmp;rm tmp"My God, why would redirect the output to a file only to cat the file to stdout again and then delete that file, that is absolutely horrible, you barbarian ;)

I see what you were trying to do, you wanted to get rid of the error messages, but there is a easier, quicker and cleaner way to do that, just redirect the error messages straight to /dev/null e.g. "ls -lR /proc/ 2>/dev/null | grep mmc1"

[misterc]

Before connecting the usb cable and activating mass storage mode:
"lsof | grep mmc1" returns empty

Output of:
"ls -lR /proc/ | grep mmc1> tmp;clear; cat tmp;rm tmp" is empty also:

that's simply rubbish;
this command will never return anything, ever

/proc/irq/86/mmc1:
[root ~]#

Output of:
"lsof /dev/media/" is "lsof: status error on /dev/media: No such file or directory"[...]

apologies on that one; command should be

lsof /media/mmc1

(for micro SD)

respectively

lsof /home/user/MyDocs

for the internal storage

[impeham]

Nevertheless, i still have this problem - command shows nothing for the mmc, and still, i'm unable to connect it.

Any other ideas?

Well, as far as I can say, you still dit not try unmounting the mmc folder ON N900 BEFORE connecting the phone to the PC, or did you?

umount -l /wherever/mmc/is

i did. umount works well - no errors and the files in /media/mmc1 disappears after i run it and still - connecting the cable afterwards + activating mass storage gives me the error.

Hm, then I have no idea. I would check with different computers (various OSs) if you did not do it already. But I doubt it would change anythingm but you never know.
