Accessing memory of Sony Ericsson k750i under Linux

Question

I want to retrieve some photos taken with the camera on this mobile phone. But upon connection, it doesnt automount. An icon is displayed in computer:/// in Nautilus (Ubuntu/Gnome). But upon doubleclicking, I get an error about it failed to mount.

The phone is listed (by name) in lsusb when connected.

Comparing ls of /dev when the phone is connected and when its not displays some extra devices detected on the phone:

$ diff deva devb
4a5
> cdc-wdm0
82a84
> serial
84a87
> sg2
156a160,161
> ttyACM0
> ttyACM1

> usbdev6.10_ep82
> usbdev6.10_ep83
> usbdev6.10_ep84
> usbdev6.10_ep86
> usbdev6.10_ep87

When connecting, the dmesg displays a few errors about the phone:

A /dev/sdc shows up when the phone is connected (strange it isnt displayed in the diff), but no /dev/sdc1.

The phone works as expected under Windows. Ive tried some phone related software under Linux (like Wammu) but none has succeeded in accessing it. I just want to retrieve the photos (files) no contact/sms syncing or any other advanced operation.

Google found some success stories but nothing that helped me make progress. Tried to get help from #ubuntu but nothing there either.

• Could the memory on the phone be corrupt?
• Can the phones memory be accessed like a regular flash drive?
• ... or do I need special Linux drivers?
• Help! :)

It seems like Linux is trying to use your phone as a modem, which is clearly not what you are trying to achieve. Don't know about the k750i, but on the SonyEricssons I had, you could configure what kind of connection the phone should perform when plugged into a computer via USB.
