Re: Problem using xawtv with Quickcam Express

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Try to copy mod_quickcam.o to the lib kernel (USB) directory, it may help you
to remove the error "Can't locate module char-major-81-0". Let me know if that
works or not.

I was told that insmod should insert the path of mod_quickcam.o into kernel
automatically, and it should not be necessary to edit modules.conf either. But
I found it does not work at that way, someone may be able to clarify it.
