thanks, it works great. To avoid the search the patch is this one:

I would like to know what are the signs which force you to add an UNUSUAL_DEV entry in unusual_devs.h ?

Hi all,
I've bought the above device and I would like to use it with linux.
I suppose it's considered as an usb mass storage.
when I connect it to my desktop (usb connection) usb-storage module is loaded by
the kernel.
In /proc/bus/usb/devices I can read :
T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#= 7 Spd=12 MxCh= 0

E: Ad=82(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
The Driver usb-storage is not associated with my device !!!
I was thinking that my kernel did not know how to handle this device and I've
added the line below in
/usr/src/linux-2.6.7/drivers/usb/storage/unusual_devs.h, but my kernel says
"kernel: usb-storage: This device (132b,0013,0001 S 06 P 50) has an unneeded
SubClass entry in unusual_devs.h" and so I think it already knows it.
UNUSUAL_DEV( 0x132b, 0x0013, 0x0001, 0x0001, "Minolta", "DIMAGE X31", US_SC_SCSI, US_PR_DEVICE, NULL, 0 ),
Any help is welcome :-)
The DiMAGE cameras have a number of problems. I can't tell from your message what your particular problem is, though. Try doing this: Take out your unusual_devs.h entry and turn on the usb-storage verbose debugging option in the kernel configuration. Then rebuild the driver, try plugging in the camera, and post the debugging messages that show up in the system log.

See what I get after having activate verbose messages in usb-storage:
