As was pointed out, I didn't mention the camera type: I am trying to connect my Canon Powershot G2 to my Linux system via a USB port. Red Hat 9 does not seem to be seeing my digital camera when I connect the camera to a USB port. (And it was working well on Red Hat 8 with gphoto2 -- I did a fresh install, not an upgrade.) USB is working. I have a Keyspan serial port device attached to the same system. The Keyspan is working and I see it as: /proc/bus/usb/001. (And the Keyspan is listed in /proc/bus/usb/devices) I expect the camera to show up as /proc/bus/usb/002 (It did in RH8). However, there are no additional entries in /proc/bus/usb, nor any messages in /var/log/messages after I connect the camera. Also, the camera is not listed in /proc/bus/usb/devices. The following usb drivers are loaded: /proc/bus/usb]$ cat drivers usbdevfs hub 96-111: hiddev hid serial I also tried using different USB ports on my epox 8RDA+ motherboard. Any suggestions on how to get my Linux system to see my digital camera would be appreciated.
