Can't mount USB memory 11.2

I am having an issue similar to others - have tried the many suggestions to no avail.

Here is the “frequently requested info” :

I find it interesting that dosfsck reports FAT32, yet fdisk reports FAT16.

Any suggestions out there?

Some more info like kernel messages (tail -F /var/log/messages as root) when plugging in the device and trying to mount it would be useful.

Here are all the lines associated with the device insertion:

Here are the messages when attempting to access the device (with Digikam).

I am off to search for modules.dep
Suggestions appreciated.
Thanks

Try this:


su -c 'mkinitrd'
(enter rootpassword)

This would create a new ‘initrd’

Did you run the updater today? It may have installed a newer kernel (your reported one is not the latest from Update). Reboot and see if the problem persists.

Yes, I found that I had received a kernel update recently, was running -1 but -2 was installed.
S2RAM works so well I don’t reboot enough, I guess :).

I rebooted, but unfortunately my mouse pointer disappeared, mouse is moving but I have no visible pointer) so I am distracted chasing that at the moment.

Two days ago my mouse-pointer disappeared too, with the same symptoms. My problem was related to me trying to solve another problem I had with the ATI driver, so this may not apply to you.

The problem was solved by uninstalling all the graphics drivers (I had fglrx and radeonhd). Then the machine failed to start X (obviously) and then installing only the driver from ATI’s site. Just do not forget to download the ATI driver first, otherwise it will be really hard to get it.

Good luck!

Thanks for the suggestions from all.

Root cause: I needed a reboot to complete the recent kernel upgrade. As noted, I was running -1 but modules.dep was being loaded from the updated directory for -2.
Of course, rebooting caused an issue with my fglrx driver, which caused the mouse pointer issue.
After reinstall of fglrx and compat-wireless, my DV7 is back to running well and mounting USB sticks
