[Linux-uvc-devel] Logitech Quickcam Orbit problem/report

[THOMAS D. V. <tho...@gm...>]

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.

Nothing too helpful out of `dmesg`:
