I think I'm missing something really fundamental here, but I can't figure it out.
I have USB support compiled into the kernel & everything works sort of ok, but not perfectly. This is what happens...
I plug in the Cam and dmesg says
| Code: | usb 1-2: new full speed USB device using address 3
scsi0 : SCSI emulation for USB Mass Storage devices
Vendor: NIKON Model: DSC E5200 Rev:
Type: Direct-Access ANSI SCSI revision: 02
Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0
Attached scsi generic sg0 at scsi0, channel 0, id 0, lun 0, type 0
USB Mass Storage device found at 3
|
Then I do a mount -t vfat /dev/sda /mnt/nikon & that says :
| Code: | mount: wrong fs type, bad option, bad superblock on /dev/sda,
or too many mounted file systems |
dmesg at this point throws out :
| Code: | SCSI device sda: 499712 512-byte hdwr sectors (256 MB)
sda: Write Protect is off
sda: Mode Sense: 18 00 00 08
sda: assuming drive cache: write through
SCSI device sda: 499712 512-byte hdwr sectors (256 MB)
sda: Write Protect is off
sda: Mode Sense: 18 00 00 08
sda: assuming drive cache: write through
/dev/scsi/host1/bus0/target0/lun0: p1
|
and then there is a sda1 created in /dev
Then mount -t vfat /dev/sda1 /mnt/nikon works like a charm...
I've tried this on various 2.6.x kernels & I can't figure out why this happens...hope someone can help me out  |

I've seen strange things with devfs and udev when dealing with hotplugged devices. Try listing /dev/sda* after attaching the camera but before trying to mount the device. i.e. ls -l /dev/sda*
Don't know if it will make a difference, but it will be interesting if it does. |

Before mounting, I get only /dev/sda & that's the only sd* device.
What makes me think I'm not doing something right is, The same happens with my friend's 80 GB USB HDD on a Gentoo install that I setup on his laptop...so I must be doing something messed... |
