Hi,
I¹ve been successfully using a Logitech QuickCam Pro 9000 with the linux-uvc
module (iirc, linux-uvc-0.1.0_pre173) for a while. Recently, I installed the
devel version of v4l in order to test out the new hd-pvr driver.
Unfortunately, while the hd-pvr module is working nicely for me, it appears
that the new version of uvcvideo isn¹t. Below is the dmesg output when the
system attempts to load the module. Any suggestions on what might be causing
the issue or what steps to take to work around it would be greatly
appreciated.
Thanks,
Joe
