When I do make install in bcwc_pcie directory I get the following error:

make -C /lib/modules/4.4.0-57-generic/build M=/home/calypso/bcwc_pcie modules_install make[1]: Entering directory '/usr/src/linux-headers-4.4.0-57-generic' INSTALL /home/calypso/bcwc_pcie/facetimehd.ko At main.c:222:

Please help!

The errors says that the module is not signed. That is not an issue and it does not prevent the driver from working correctly.

Modules can be signed to guarantee that thew don't contain malicious code (kind of..). There is no need for bcwc to be signed at this stage. it is open source and you compile it yourself. Therefore just trust it :)

How do I get ahead with the installation and ignore this error, anyhow?? The camera is not working even after the installation.

Try: sudo depmod -a sudo modprobe facetimehd

mrinalsaurabh commented 7 years ago

tried it.. now it says on $ sudo depmod -a sudo modprobe facetimehd depmod: ERROR: Bad version passed sudo

WhyNotHugo commented 7 years ago

It's:

sudo depmod -a
sudo modprobe facetimehd

There's a line jump in the middle that got formatted away.

xgnata commented 7 years ago

You probably need to start with sudo modprobe -r bdc_pci

Be careful using sudo if you have no idea what you're doing with the command line : You can easily ruin your system.

mrinalsaurabh commented 7 years ago

The commads did not give any error, but the webcam was still not detected. :( Is it time to give up already?

xgnata commented 7 years ago

sudo modprobe -r bdc_pci sudo depmod -a sudo modprobe facetimehd

and post the result of dmesg (it is a command. Just type dmesg after completion of sudo modprobe facetimehd) The display of dmesg is very long. We are only interested in let's say the last page. only the lines talking about facetimehd.

mrinalsaurabh commented 7 years ago

I did a dmesg | grep facetime and got following. Does this suffice? [ 90.065067] facetimehd: module verification failed: signature and/or required key missing - tainting kernel

Stono commented 7 years ago

The taining kernel doesn't really matter; that's because it's an unsigned mod. You can create an entry in /etc/modules-load.d to have it load at boot.

Check my gist https://gist.github.com/Stono/990ea9f0b3c41606c292f00382d421bf

checkInstall dkms did not work too for me.

After doing: sudo modprobe -r bdc_pci sudo depmod -a sudo modprobe facetimehd

I get below in dmesg
