Having trouble hooking up a Canon PowerShot S200
I'm trying to use gphoto2 to grab pictures
off of my Canon PowerShot S200, but I cannot
get hotplugging to work.
I'm using Debian 3.0 (testing) and the package I'm using is hotplug 0.0.20020401-4. I have USB support all enabled (I'm using it for my modem right now and I've also used it for my mouse in the past), and I've turned on CONFIG_HOTPLUG. /proc/sys/kernel/hotplug points to /sbin/hotplug and the file exists. I also have an /etc/init.d/hotplug file. I have noticed, however, that when my hotplug is run, I get the message:
Starting hotplug subsystem: usb
** can't synthesize root hub events
I'm assuming this is bad. Why would this happen?
My usb.usermap file looks like this:
# usb.usermap file
# This is autogenerated by update-usb.usermap program
# usb module match_flags idVendor idProduct bcdDevice_lo
bcdDevice_hi bDeviceClass bDeviceSubClass bDeviceProtocol bInterface
Class bInterfaceSubClass bInterfaceProtocol driver_info
# libgphoto2

....There's a bunch of them. I have a file called /etc/hotplug/usb/usbcam for starting all of this up that looks like this:
-rwxr-xr-x 1 root root 1039 Sep 12 21:30 usbcam
Whenever I turn my camera on and plug it in, nothing seems to happen. I see no messages in /var/log/syslog, /var/log/messages, or dmesg.
If any of you could provide insight into this, I would greatly appreciate it. I would love to use my digital camera in Linux. Please let me know if there is any additional information you need to know.
Oh yeah, I'm running kernel 2.4.19.

You don't have the "usbmodules" program installed.
It's not necessarily "bad", it just means that the hotplug events that were dropped on the floor while your system was booting ("coldplug" events) couldn't be recovered later. Workaround: unplug your USB devices, then plug them in again.

Sounds like some sort of USB level problem. Are you sure you have the right USB host controller driver loaded? On 2.4 that'd likely be "usb-ohci", "uhci", or "usb-uhci".
