Canon a300 view by gphoto2 but not as fs
hello all,

I have a FC3 system with usb1.1, a digital camera canon A300, and I am trying to install it as a masse storage system.

I have a very important mediacard full of photos but the file system in it is corrupted, I beleive only linux will let me access it.

the problem is that if I plug my camera on the usb plug, Gphoto2 detect the camera, import what can be import, but I cannot moun the camera.

dmesg only list (on the last line):
usb 1-1: new full speed USB device using uhci_hcd and address 1

there is no recognision of scsi device
usbcore is compile in the kernel
lsmod shows

ohci_hcd 24084 0
sg 34464 0
sd_mod 16384 0
usb_storage 62280 0
scsi_mod 122240 3 sg,sd_mod,usb_storage

You'll have to tell the camera to work in 'USB Mass Storage' mode. So enter the setup section of the camera and see if that is possible.

If your camera can only work using its proprietary format, you're probably best finding a card reader for your memory card and trying that.
