As the tittle sujests really.

After i updated to PR1.3 i can no longer use my phone in mass storage mode.

If the phone is on it always says 'device in use'

If its off it just doesnt do anything.

I have tried a thousand restarts and no joy.

It will always detect the SD card though!

please help

To my mind it would make sense that if any applications have open file handles on the MyDocs partition then it wouldn't be unmounted and exported as USB mass storage.

You can list the open files on that partition by entering the following command in an Xterm:
If you get no output there are no open files, and my guess is incorrect.

Hi thanks for the reply.

i did exactly as you said, when i pressed enter it stalled for a second then just dropped down aline.

No output i guess?

I hope to get this sorted

Have you tried to take off battery for couple of minutes and then restart phone? Have you installed any stuff from testing & devel repositories?

I'm getting the same thing on Ubuntu 10.04.

Laptop recognises my other phone and it's SD card, but only the SD card of my N900. Tried searching for a workaround from an Ubuntu perspective, but suspect this may be an N900 issue.

I did not have this problem prior to PR1.3 - anyone have any ideas?

Mass storage mode is working fine for me on PR1.3 (flash method, not OTA).
@CraigRobbo: That's correct: no output, suggesting there are no open files. Does any USB activity work correctly for you? Things like Ovi Suite? I'm worried perhaps your N900's USB port is starting to fail.

After choosing mass storage this command should also give no output:
mount | grep MyDocs

For reference when I connect and select mass storage mode dmesg on the N900 shows:

On my desktop dmesg gives:

Okay guys, i think i have it working for now.

I left the battery out for about 30 minutes, plugged her in and so far so good!

What is odd is that, i have done this before and it never worked!

Ill see how its going and keep you guys updated!

Don't forget that if the tracker is scanning a mounted partition, then it can't be unmounted to allow the host PC to access it via usb. Always wait after a reboot until the tracker has finished running before attempting to usb mount your N900 from a host PC.

Noob qeustion alert:

Whats a tracker?

It normally works but well has habit to sometimes get in loop.
