me with blank images t4thfavorFebruary 9th, 2010, 07:37 PMI have 2 webcams installed on my ubuntu server, I have used them both in the past, both on Linux and Windows. Currently I have tried webcam-server, and motion. The output is a blank image. It looks like the brightness is set all the way up or something. I have a logitech QuickCam express (looks like a ball) and a 3com homeconnect (old) #lsusb Bus 004 Device 002: ID 04c1:009d U.S. Robotics (3Com) HomeConnect WebCam [vicam] Bus 002 https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=27420 Device 003: ID 046d:0920 Logitech, Inc.
