Hello,

I've just bought a digital camera, and I am trying to get it work
under Linux. The camera is a Minolta DiMAGE G400.

To get access to the camera, I have built a new kernel with the
following configuration:

CONFIG_SCSI=m
CONFIG_BLK_DEV_SD=m
CONFIG_SCSI_QLA2XXX=m
CONFIG_USB_STORAGE=m

In /etc/fstab, I have defined the following entry:

/dev/sda1 /dimage auto defaults,user,noauto 0 0

When I plug in the camera, I can see that it is correctly
recognized as /dev/sda1. Hereafter /var/log/messages output:

kernel: usb 2-1: new full speed USB device using address 2
kernel: SCSI subsystem initialized
kernel: Initializing USB Mass Storage driver...
kernel: scsi0 : SCSI emulation for USB Mass Storage devices
kernel:   Vendor: MINOLTA   Model: DiMAGE G400       Rev: 1.00
kernel:   Type:   Direct-Access                      ANSI SCSI revision: 02
usb.agent[1874]:      usb-storage: loaded successfully
kernel: usbcore: registered new driver usb-storage
kernel: USB Mass Storage support registered.
scsi.agent[1916]: disk at 
/devices/pci0000:00/0000:00:04.3/usb2/2-1/2-1:1.0/host0/0:0:0:0
kernel: SCSI device sda: 494080 512-byte hdwr sectors (253 MB)
kernel: sda: assuming Write Enabled
kernel:  sda: sda1
kernel: Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0

I can then mount it...

I have observed the following problem:

If operating from the console (no Gnome session started), I can
properly copy/move files from/to the camera (cp and mv
commands). Fine!

BUT... as soon as I open a Gnome session, and then even if
operating from the console (not a gnome terminal, I really mean
the console, CTRL-ALT-F1...) I will get some error messages about
timeouts:

kernel: usb 2-1: control timeout on ep0out
or
kernel: usb 2-1: control timeout on ep0in

So, it seems the problem is related to the Gnome session.

Does anybody have similar issues? If so, how can it be solved (if
possible)?

I have to make the system easily useable by my wife, and Nautilus
is needed for that purpose, I can't ask her to kill her Gnome
session and do it from a console...

It is a pity that with XP you just plug the camera and it works
out of the box, and that under Linux it will take me days to get
the same result :-(

Thanks for your help.

Regards,
