I'm no expert but it looks to me like USB is working. Perhaps you need to make the device nodes for /dev/sd*? You can find out the details in /usr/src/linux/Documentation/devices.txt, for example: # mknod /dev/sda1 b 8 1
I tried to create the device but then when i try to mount the filesystem i get the following error: bash-2.05b# mount -t vfat /dev/sda1 /mnt/camera; mount: /dev/sda1 is not a valid block device
Also, I noticed something new.
I don't get the entry /dev/sda* created when i plug the camera but
i get the following trace in syslog:
usb.c: USB disconnect on device 00:07.2-1 address 3
usb.c: USB device 4 (vend/prod 0x4a9/0x3075) is not claimed by any active driver
The number '4' increases everytime i plug my camera. So it seems that something happens but this is not enough for me to be able to create this entry /dev/sda...
I have ben looking on the gentoo forum. I found a lot of similar threads. I found - one which said there was a bug in the scsi driver - one which said we need a module 'hotplug' - one which says 'usb-uhci' instaed of 'uhci' (How can i know which one is good for me? uhci or usb-uhci?)
It seems to be a common problem with no generic solution :-(
