Question

.. because it cannot find gspca. My log:

But I have lots of gspca's:

The only difference I have with respect to a standard installation is that I downloaded an older version of the backport drivers, and in doing so I surely re-installed gspca.
So my questions are: where is systemd-module-load searching for gspca? How can I persuade it to search in the right directory? And in any case, why is it searching for it in the wrong place to start with?. Just in case,

Answer 1

Problem solved, thanks to both of you guys. For some resason, I had a webcam.conf file in /etc/modules-load.d containing the single line *gspca*, which is not a module: both modprobe and insmod fail, because the correct module name is one of those listed in /lib/modules/`uname -r`/kernel/drivers/media/usb/gspca. They are called gspca_benq.ko       gspca_konica.ko and so on. I simply deleted the file since I  do not need it.
As for backport drivers: this site, http://drvbp1.linux-foundation.org/~mcg … backports/ has the most recent versions of Linux drivers, backported so that older kernels can install them (I understand this is not a concern for fellow Archers). Whenever I need to upgrade (mostly on Debian) or downgrade (a few times on Arch, because an older version of a driver is free of a newly minted bug) I download these drivers, compile them and install them from source.
