I have a Logitech Quickcam Orbit. The driver built, installed, and loaded fine on Ubuntu Hoary x86. All my apps complain about not being able to open /dev/video0. I ran a test program that was posted to the list in January. The results are below. I'm posting this for feedback to the developers. I don't require a response. I checked this driver out of the subversion repository today. Thanks much for the work on this driver. -Tom $ uname -a Linux dreamscometrue 2.6.12-10-686 #1 Sat Mar 11 16:22:51 UTC 2006 i686 GNU/Linux $ lsusb Bus 005 Device 003: ID 046d:08c2 Logitech, Inc. $ lsmod | grep uvc uvcvideo 32676 0 v4l1_compat 14692 1 uvcvideo videodev 9440 1 uvcvideo v4l2_common 5728 1 uvcvideo usbcore 118044 8 snd_usb_audio,snd_usb_lib,uvcvideo,ndiswrapper,usb_storage,ehci_hcd,uhci_hcd $ ./test /dev/video0 Device /dev/video0 opened: .
