Hi,
I bought the camera(Sony DS-P150 - 7.2 MP), I mentioned a few days back. I
havent had a problem running it on either of my desktops, which run
Fedora/Suse/Mandrake. It runs flawlessly under both modes... USB Mass Storage
and PTP. I faced some issues though, while getting it to work with Slackware,
which runs my notebook. I wasnt planning to use gphoto2, which in any case
doesnt ship with Slackware. I started off to use USB mass storage. But I
faced a problem right away

I did have all the necessary modules loaded, so I didnt see a reason why it
shouldnt work.

I then downloaded gphoto2 and digikam, but that didnt work either. In fact I
had my hotplug system messed up, cos /proc/bus/usb/devices didnt exist. I
solved this part with a "mount -t usbfs none /proc/bus/usb". I made an
appropriate entry in /etc/fstab for the same. But even then /var/log/messages
doesnt report the usb-storage driver or scsi_mod seeing the camera. Also a
#cat /proc/scsi/scsi gives
Attached devices: none
While digikam was autodetecting the camera in PTP mode, it failed to
connect/download from the camera. I solved this problem with a minor tweak:
a) Added the following lines to /etc/hotplug/usb.usermap
# usb module match_flags idVendor idProduct bcdDevice_lo bcdDevice_hi
bDeviceClass bDeviceSubClass bDeviceProtocol bInterfaceClass
bInterfaceSubClass bInterfaceProtocol driver_info
# USB PTP Class Camera
usbcam 0x0080 0x0000 0x0000 0x0000 0x0000
0x00 0x00 0x00 0x06 0x00
0x00 0x00000000
b)Next I hand created the script /etc/hotplug/usb/usbcam to read thus
#!/bin/bash
if [ "${ACTION}" = "add" ] && [ -f "${DEVICE}" ]
then
chmod a+rw "${DEVICE}"
fi
a chmod u+x /etc/hotplug/usb/usbcam finished the job. I am now able to use a
digikam+gphoto2 combo to access the camera through PTP. However PTP isnt
really my first choice as it drains the batteries very fast as Siddhartha-da
indicated. I still want to use USB Mass Storage, and I happen to be facing
issues with that. Everytime I try to do a
# mount -t vfat /dev/sda1 /mnt/camera
I get "mount: /dev/sda1 is not a valid block device". I think I am at a dead
end here, because "tail -f /var/log/messages" doesnt show the camera being
claimed by the usb-storage driver. OTOH /proc/bus/usb/devices does display
the device when plugged in via Mass Storage mode. Any hints??
Try automounting the device. The message from mount is not specific. I
have a fresh slackware-10 (quite new for me) installed. ..will try that.
