Hi!

I tried to mount my Olympus U760 digital camera connected to an USB port on my Chaintech portable desktop computer but this device is not recognized.

Helps will be greatly appreciated.

TIA

Is your camera set to USB mass storage mode?

I can't find the menu for this setting. Win XP is able to download files with the present settings without any problem.

My Sony DSC W35 has several modes, one of which is USB mass storage mode.
The other modes do not work for me.

I do not have any experience of other models though.

if it wont mount try gphoto2

outputs
ptpip:
usb:

detects nothing.
By the way, I did not mention this:
After the camera is connected to the USB port on my PC, the camera pops up 4 menu options: Then I pressed "PC" button and the camera shows "one moment" and go blank and the red indicator lights up, and modules usb_storage and scsi_mod are automatically loaded. The problem is that the /dev/sda1 is not recognized as mentioned earlier.

Now I unloaded usb_storate and renamed file usb_storage.ko to bogo.ko so it would not be automatically loaded after "PC" button is pressed. Then I pressed "PC" button and the camera kept saying "one moment", and lists nothing.

Olympus µ760 is not on the list of:

Do not wish to discourage you,
but why not use a flash card reader?

You ran gphoto2 as root right ?
