Hello everyone. I'm trying to get a webcam to work with Puppy Linux 2.00. This distro has a 2.6.16.7 kernel. I tried to load the module usbvideo.ko using:

modprobe usbvideo

The result was:

usbvideo: Unknown symbol v41_compat_ioct132
usbvideo: Unknown symbol video_devdata
usbvideo: Unknown symbol video_unregister_device
usbvideo: Unknown symbol video_register_device
usbvideo: Unknown symbol video_usercopy

Does anyone know what these errors mean, or if the problem can be fixed? Thanks.

Steven.

"Unknown symbol" means that some program or file is trying to access an external function from another file that doesn't exist. I don't know much about usbvideo, but from what I can tell, you are missing some video drivers, or they're outdated.
