Attaching a camera via USB

[Shahar Dag]

Hello

Many digital camera has 2 data transfer modes.
One is the disk like mode (same as DiskOnKey)
And I don't remember the name of the second.
Dig inside the menus & verify that you are in the correct mode.

When I bought my first digital camera (Nikon coolpix 4200), my dealer recommended me to use a card reader. According to his experience, many cameras become total lost because of the usage of the usb cable

  My son got an inexpensive digital camera and I am trying to plug it in 
  to an Ubuntu system to be able to copy off the pictures.  When I plug in 
  the camera to the USB a light on the camera flashes but the device is 
  not detected as a storage device.  When I run lsusb it sees the device

  Bus 003 Device 006: ID 0979:0227 Jeilin Technology Corp., Ltd

  lsusb -v for that device shows

  I do not know how to move forward on getting this device to work as a 
  storage device.  I do not need to use it as a webcam (which 
  theoretically it can do) I just want to be able to copy off the pictures 
  and delete them.  I tried searching but wasn't able to narrow down the 
  search enough to be useful.  Any help on how to do this or pointers to 
  online resources on how to do this would be appreciated.


  Thanks,
