Bug 59215

First of all, have you updated to the latest errata kernel?  At the time of
writing it's 2.4.9-21 (http://www.redhat.com/support/errata/RHSA-2002-007.html).

Secondly, you ought to be able to use USB with this camera.  It certainly works
with my DC240.

The kernel version that I'm running is 2.4.9-21 dated January 17, 2002. 
HOWEVER, the
serial connection DID work this morning, though there is no question that it did
NOT work
several times before.  I can't think of anything that is different at the system
level.

Concerning USB, which doesn't work with either version of the kernel (2.4.7 or
2.4.9),
at least not on my IBM Thinkpad, here's what I've done:

mknod -m 0660 /dev/usb/dc2xx0 c 180 80
mknod -m 0660 /dev/usb/dc2xx1 c 180 81

then modprobe dc2xx.

dmesg reports the following when the camera is turned on in 'connect' mode:

usb.c: registered new driver dc2xx
dc2xx.c: v1.0.0:USB Camera Driver for Kodak DC-2xx series cameras
hub.c: USB new device connect on bus1/1, assigned device number 2
dc2xx.c: USB Camera #0 connected, major/minor 180/80

and /proc/bus/usb/devices shows:

P:  Vendor=040a ProdID=0120 Rev= 1.08
S:  Manufacturer=Eastman Kodak Company
S:  Product=KODAK DC240 Zoom Digital Camera
C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr=100mA
I:  If#= 0 Alt= 0 #EPs= 2 Cls=00(>ifc ) Sub=00 Prot=00 Driver=dc2xx
E:  Ad=01(O) Atr=02(Bulk) MxPS=  64 Ivl=  0ms
E:  Ad=82(I) Atr=02(Bulk) MxPS=  64 Ivl=  0ms

So all appears to be well (?).  In gphoto I specify the /dev/usb/dc2xx0 device.
But when I try to get the index of photos from the camera, all I get is this on
the terminal:

state_machine_set_baud: tcgetattr: Inappropriate ioctl for device
Assuming USB connection.
state_machine_run: read: Invalid or incomplete multibyte or wide character
kdc240_read_packet_error: read error
state_machine_run: write: Timer expired
state_machine_run: write: Timer expired
kdc240_read_ack_error: read error
num_pictures_taken is 0

There are actually 8 pictures in the camera.  The index is not retrieved and the
camera
hangs; i.e., I can't turn it off without removing the batteries.

I get exactly the same values in /proc/bus/usb/devices, and yet it works for me.
 Perhaps it's a different USB controller.

Please attach the output of 'dmesg' after you have tried a USB connection, and
also after you have tried a serial connection?

Changing component, since it really looks like a kernel bug.  read() is
returning with errno set to EILSEQ, in the USB case.

The serial connection with gphoto now seems to work fine.  I have
no idea what is different between when it didn't work and now.
I tried it several times after upgrading to kernel version 2.4.9-21
via the Redhat Update Agent, and it didn't work until now.

Anyway, here's the output from dmesg before connecting the
camera to the USB port and turning it on:

----------------------------------------------------------------

After connecting via the serial port there are no new messages
from dmesg or in /var/log/messages.

After connecting the camera to the USB port and turning it on,
dmesg adds the following to the end:

hub.c: USB new device connect on bus1/1, assigned device number 2
usb.c: USB device 2 (vend/prod 0x40a/0x120) is not claimed by any active driver.
usb.c: registered new driver dc2xx
dc2xx.c: USB Camera #0 connected, major/minor 180/80
dc2xx.c: v1.0.0:USB Camera Driver for Kodak DC-2xx series cameras

After starting gphoto then attempting to download the camera index,
dmesg gives:

usb-uhci.c: interrupt, status 2, frame# 557
usb-uhci.c: interrupt, status 3, frame# 561
usb-uhci.c: interrupt, status 3, frame# 1563

and gphoto prints:

state_machine_set_baud: tcgetattr: Inappropriate ioctl for device
Assuming USB connection.

After that I have to open the battery cover to power off the
camera.  The power switch becomes useless.

Thanks in advance for any further help you can provide!

How is the 2.4.20-18 doing?

I gave up on this long ago, but just tried the camera through the USB port
again.    It appears to work just fine!  I'll test it more in the future, but
for now it is working.  I'm running Redhat 9 with kernel 2.4.20-18.9.  Thanks.

Hmm. I think the dc2xx driver was thrown out from the tree recently,
and gphoto switched over to a userland driver with usbdevfs/libusb.
Perhaps that helped.

I'll close now.
