Subject: CPiA cam problem
Date: Wed, 14 Apr 2010 15:09:33 -0700	[thread overview]
Message-ID: <4BC63D1D.60706@onid.orst.edu> (raw)

I have an old Ezonics EZCam P10U that I dug up and tried to get 
working.. but wasn't able to get any video from it.  dmesg and relevant 
VLC messages below.  Tested on Debian linux kernel 2.6.32-3-amd64.  Am I 
doing something wrong?  Those cpia error messages don't look too 
happy..  VLC gives the same error when testing on Windows XP.  Is my 
camera dead?
