I'm getting an error while trying to insert a module. What am I doing wrong?

orsty9001 · 07-27-2014, 08:23 PM

I'm running slackware 14.1 and I'm trying to install a DVR card for zoneminder. The card is supposed to use BTTV. This is the error I get when trying to set it up.

modprobe: ERROR: could not insert 'bttv': Invalid argument

I tried:

modprobe bttv

modprobe bttv card=150,150

modprobe bttv tuner type=150,150

You are doing this as root, yes?

What does

Code:

modprobe -l | grep bttv

return?

I get an error. Also I'm running it as root.

Code:

modprobe: invalid option -- 'l'

notKlaatu · 07-28-2014, 09:27 PM

try this instead:

Code:

find /lib*/modules/`uname -r` -type f -iname "*bttv*"

to see if the module for your currently running module is installed.

Looks like it's there.

Code:

/lib/modules/3.14.12/kernel/drivers/media/pci/bt8xx/bttv.ko

modinfo bttv shows this.

Code:

Then a lot of parameters for the module.

Try

sudo insmod /lib/modules/3.14.12/kernel/drivers/media/pci/bt8xx/bttv.ko

If that works, I suspect your problem has something to do with module dependencies rather than the bttv module itself.

Looks to me that your kernel is built without support for some of the modules that bttv (or maybe bttv itself) needs to control. C think if you compiled a new kernel, explicitly setting support for bttv, that this problem would probably be resolved.

Last night on my Slackware laptop, I was able to modprobe bttv without error, and that was with the default huge kernel config. What distro are you on, and can you recompile the kernel?
