Copying files from a cell phone


This is all new to me so I appreciate any help.

All I want to do at the moment is copy a camera photo from a cell phone to my desktop.

The phone is an LG 440G. The phone does not have an micro SD card or slot.

Although the phone is bluetooth capable, I don't yet have a bluetooth dongle. I have a micro USB cable.

Connecting the phone when powered off results in the device being assigned the /dev/ttyACM0 device node with ownership of 660 and root:dialout.

Connecting the phone when powered on results in no device node assignment.

Powering on the phone while connected results in the device node being removed.

First hurdle is I need a udev rule to force the device to belong to the plugdev group rather than dialout. I thought I had a rule but the device keeps being assigned to dialout:

/etc/udev/rules.d/99-lg440g.rules:

KERNEL=="ttyACM0",SUBSYSTEM=="tty",ATTRS{manufacturer}=="LG",ATTRS{product}=="LG 440G", GROUP="plugdev", MODE="0660"

The rule is not working.

When I manually change the device node group to plugdev, or I add my user account to the dialout group, gammu --identify can access the device. I receive some sane information. I tried several gammu commands but am told the function is not supported. So after getting past the udev rule, how do transfer files from the phone?

Thanks.

I don't know if this helps. Normally you'll have to select on the device if it should act as a modem or USB-memory.

My phone is Android, and I downloaded an app called AirDroid that allows me to connect to the phone through my home wireless network and Firefox. I download my pictures that way.

The OP's cellphone seems not to have wifi.

BTW: I use AndFTP with my smartphone (an FTP-client) and I have vsftp configured on Slackware, it's very convenient for up- and download).

I just looked up his phone and see that I am barking up the wrong tree. Sorry Woodsman.

More information:

The LG 440G is not a smart phone. Just a plain flip phone. Tracfone. Not Verizon. Not Android. To the best of my knowledge, Tracfone uses GSM and piggy-backs on the AT&T network. No micro SD card.

http://lowermybills.phonedog.com/cel...40g-black.aspx

Being just a basic phone, I have not found any menu option to select on the device whether to act as a modem or USB-memory.

The phone works well enough as a phone. No complaints because that is all I really want. I haven't used the camera in any serious manner, but if I did I need a way to transfer the files.

The phone has bluetooth capabilities but as I don't (yet) have a bluetooth dongle I can't test that. Possibly bluetooth will resolve the problem, but I'm curious how to access the phone with the mini USB cable.

For the moment I ask for help with the udev rule to force the device node to be assigned to the plugdev group and not the dialout group.

Thanks.

I'm not sure you are heading in the right direction by trying to alter the group assignment. If the phone gets detected as /dev/ttyACM0 device - it means that it is presenting it's modem/serial interface to the computer over usb. To my knowledge, that is of no use if you are trying to download pictures from it. It is of use, however, if you are trying to use it as a GSM dial-up modem to connect your computer to the Internet through the mobile phone connection (if your phone is on a suitable data plan).

Back to your problem, all devices I've encountered can only present one interface at a time through USB (either modem or storage), so your best chance is to find somewhere in the phone menus an option for switching the USB connection to data storage mode (or a similar name). This will expose a mass storage device over the USB cable to the computer - which will detect it accordingly as (hopefully) /dev/sdX. Even S40 series Nokia's (the feature phone variety) have been able to do this since forever - so hopefully the LG has a similar option. However, I'm not familiar with this model, so can't give more precise guidance.

Hope the above helps

A note to future readers: I resolved the problem using bluetooth. The LG440G supports "File transfers." I bought a USB bluetooth adapter for the computer and can transfer photos from the phone to my computer.
