To steal ideas from one person is plagiarism;
to steal from many is research.
I'm trying to access a USB digital camera under RedHat null Beta2
The Camera information is as follows:
USB Epsilon 1.3 (Digital Dreams)
Resolution 1600 x 1280 pixels
Image sensor CMOS
LCD Screen 1.5" colour TFT
Internal memory 8MB NAND Gate Flash
External Memory Build in Smart Media card slot
Viewfinder Optical
Digital zoom X 4
Image capacity (with build in memory) 1600x1200 - 20
1280x1024 - 29
640x480 - 121
White balance Auto/Day/Shade/Bulb/Fl
Exposure Auto/Manual
Image format JPG, AVI (through software)
Computer interface USB
Power control Auto off (10 seconds)
I'm running a standard kernel 2.4.19-ac2 with USB Mass Storage degugging
Information.and also RedHat's 2.4.18-12.5
(the below messages was taken for the 2.4.19-ac2)
When I plug it in its detected as:
[root@stimpy mark]# usb.c: USB device 2 (vend/prod 0x733/0x1310) is not
claimed by any active driver.
Vendor: Model: 1.3M DigitalCAM Rev: 1.00
Type: Direct-Access ANSI SCSI revision: 02
Attached scsi removable disk sda at scsi1, channel 0, id 0, lun 0
SCSI device sda: 16384 512-byte hdwr sectors (8 MB)
sda: test WP failed, assume Write Enabled
sda1
Which means that the kernel has seen it and its being treated as a mass
Storage device, thus treated as a SCSI device.
So I also ran cdrecord -scanbus and that listed the device as well.
scsibus1:
1,0,0 100) ' ' '1.3M DigitalCAM ' '1.00' Removable Disk
After reading several pages on USB and Mass storage, I have found out
how I should be able to access it
The following Kernel modules that are relevant to this device are loaded
as below:
vfat 11356 0 (autoclean)
fat 36888 0 (autoclean) [vfat]
sr_mod 16248 0 (autoclean)
usb-storage 102352 0
usb-ohci 19528 0 (unused)
usbcore 69888 1 [usb-storage hid usb-ohci]
aic7xxx 123444 0
sd_mod 13104 0
scsi_mod 99716 4 [sr_mod usb-storage aic7xxx sd_mod]
The file system on the camera is FAT (this can be accessed by VMware
running on this Box, as a removable device (which is running a Virtual
WinXp O/S) through the USB port using the drivers for windows supplied
by the manufacturer)
mount /dev/sda /mnt/camera
and
/sbin/modprobe fat && mount -t fat /dev/sda /mnt/camera
I've also tried vat, auto, autofs and /dev/sda[0-10] as well.
Also running the following, it cannot access the device either:
[root@stimpy dev]# dd if=/dev/sda of=/dev/null bs=1k count=1
dd: reading `/dev/sda': Input/output error
0+0 records in
0+0 records out
It seems it cannot find a partition table on the device, in WinXp I can
happily right click and create folders on the camera, It can also
Identify the amount of space on the device 8MB, when first plugged it.
And I have also tried the following as well:
[root@stimpy mark]# cat /dev/sda | file -
cat: /dev/sda: Input/output error
standard input: empty
Please see below the output of dmesg -n 9, with USB Mass storage
debugging turned on (sorry for the large amount)

---------------------- cut -----------------------------
Not being a programmer or kernel developer, I'm not sure where the error
lies, Its going to be either a USB device driver bug or the actual
camera itself (thus relying on the Windows drivers doing the actual
work, rather than properly implementing USB Mass Storage)
After several conversations with the RedHat mailing list,
I have not got any closer with regards to finding out where the error
actually lies
Can anyone possibly help on this one.
Thanks in advance
Mark
