[PLUTO-help] USB e gphoto2 :(

[Giuseppe Guglielmi]

Purtroppo ho ancora problemi con la mia fotocamera digitale :(
La versione del kernel che utilizzo e' la 2.6.5.

I moduli che carico all'avvio sono:

usb_storage            59552  0
usbcore                95708  5 ehci_hcd,usb_storage,uhci_hcd
scsi_mod               65088  4 usb_storage,sd_mod,sr_mod,aic7xxx

Nel mio fstab ho inserito le seguenti righe:

none            /proc/bus/usb   usbdevfs        
noauto,users,uid=mio_utente,gid=mio_gruppo        0       0
/dev/sda1       /mnt/usb        vfat    noauto,owner,user,umask=000     
0       0

Quando collego la fotocamera al pc ricevo questi messaggi dal kernel:

kernel: ehci_hcd 0000:00:1d.7: GetStatus port 6 status 001002 POWER

kernel: drivers/usb/core/usb.c: usb_hotplug
kernel: usb 3-2: registering 3-2:1.0 (config #1, interface 0)
kernel: drivers/usb/core/usb.c: usb_hotplug

Fin qui sembra tutto regolare.

Se provo ad utilizzare gphoto2 da root tutto funzia:

/# gphoto2 --summary
Camera summary:
Model: CX4200 Digital Camera
  device version: 1.01000
  serial number:  CX42041522646
Vendor extension ID: 0x00000001
Vendor extension description: Eastman Kodak PTP Extensions

Se invece provo da utente ottengo questo output:
$ gphoto2 --summary
                                                                                

*** Error ***
An error occurred in the io-library ('Could not claim the USB device'): 
Could not claim interface 0 (Operation not permitted). Make sure no 
other program or kernel module (e.g. dc2xx or stv680) is using the 
device and you have read/write access to the device.
*** Error (-53: 'Could not claim the USB device') ***
 
I moduli dc2xx e stv680 non sono caricati nel kernel. Su quale device 
non ho permessi??????

Inoltre se provo a montare /dev/sda1 sia da user che da root non ci riesco.

# mount /dev/sda1
mount: /dev/sda1 is not a valid block device

Spero che qualcuno di voi possa aiutarmi.

Grazie a tutti
