Canon A520 not detected in Testing, but works in Unstable

["H.S." <hs.samix@gmail.com>]

Hello,

If I plug in Canon A520 digital camera to my Testing desktop, it is not
detected. The memory card in it works if I use card reader. At the same
time, the camera is detected if I plug it in a Debian Unstable computer
whose /var/log/syslog shows:

usbview does not show the camera in the Testing machine and nothing
comes up in /var/log/syslog. Other USB stuff is, however, detected
properly (mouse, card reader, etc.).

What gives? What am I missing?

Running 2.6.26-1-686 kernel. I belong to groups camera, plugdev, audio
and video among others. IIRC, the camera used to work earlier in the
year; I had been using a card reader for the past some months.

Thanks.
