Hi all,
I am trying to get my Canon S1 IS to work under Debian. I am running a
mixed testing/unstable system (mostly testing, except for libc6,
X.org, udev and linux-image and their dependencies).
It appears to me that there is some problem with SCSI emulation of my
camera. I insert the camera and /var/log/messages reports
Apr 14 21:26:25 loser kernel: usb 3-1: new full speed USB device using
uhci_hcd and address 3
Apr 14 21:26:26 loser kernel: usb 3-1: configuration #1 chosen from 1
choice
but no SCSI information after like I get with other USB devices. lsusb
shows nothing informative, but usbview correctly shows my camera
suggested. I found a bug report filed against the kernel that
suggested having ehci_hcd loaded might cause problems, so I recompiled
my kernel with the USB stuff as modules and tried different
combinations of modules loaded to see if it made a difference. The
uhci_hcd module has to be loaded to get any recognition of the camera
being plugged in, and whether ehci_hcd is loaded makes no difference.
Loading scsi_debug shows no extra information.
I tried writing a udev rule for the camera
BUS="usb", SYSFS{vendor}="Canon Inc.", SYSFS{product}="Canon Digital
Camera", NAME="camera%n"
but this has no effect. I have neither /dev/sd* nor /dev/camera* with
or without this rule.
gphoto2 cannot autodetect the camera either.
Comparing with my USB flash drive shows that the versions are
different (1.10 and 2) and the Driver is different (none and
usb-storage). This info is from /proc/bus/usb/devices, and the first
of each pair is the camera. I guess the lack of reported driver for
the camera is the problem, but I'm not sure this is possible to set is
it?
Is there a step I am missing in getting SCSI emulation of this device?
Is there anywhere else I can look for hints about what may be
happening?
Thanks,
James
