Can someone please help me install a kernel module?

Hello, I'm back with another I-don't-really-understand-linux-very-well question.

I am working on replicating a project developed by itt forum user D-rock, described in this thread. Without confusing things by over explaining what I'm ultimately trying to accomplish, right now I want to be able to run D-rock's Python code that s/he provided in post 24 of the same thread and send serial data from my n800 (os2008) to my Arduino microcontroller via usb cable.

My problem (I think) is that I don't really know how to install the FTDI driver that itt user Fanoush has compiled and provided by a link in this post of the same thread.

In D-rock's post 9 in the thread, s/he describes using the insmod command in the following manner:

I'm afraid I don't really understand this command sufficiently in order to make it install properly. Can anyone please explain to me the procedure for installing the driver?

BTW, I have to say I've traded numerous pm's with D-rock lately and s/he has been incredibly helpful. Since this question concerns something beyond the scope of his/her project (namely, my lack of knowledge about installing drivers), I though I'd give him/her a break and see if someone else might be willing to answer my questions this time.

Thanks in advance for your assistance. As always, this forum is full of really helpful people.

Re: Can someone please help me install a kernel module?

um...

as root (ie: at the # prompt), type

insmod drivers/usb/serial/ftdi_sio.ko

Re: Can someone please help me install a kernel module?

Thanks for the reply. I guess I should have mentioned in my op that I have tried to enter the code

Code:

#insmod drivers/usb/serial/ftdi_sio.ko

and xterm tells me

Code:

insmod: can't open 'drivers/usb/serial/ftdi_sio.ko': No such file or directory

Do I need to mkdir the drivers/usb/serial directory? I guess I'm confused because it doesn't look like a directory format I recognize because it doesn't start with the / (root). Is there a certain directory that I need to be working from in order to make this work? What I tried to do is transfer the ftdi_sio.ko file to the /usr/bin directory and try the insmod there. Since this didn't work I'm obviously doing something wrong. Any clues?

Re: Can someone please help me install a kernel module?

The module shouldn't really be in /usr/bin but if you put it there:

insmod /usr/bin/ftdi_sio.ko or insmod /usr/bin/drivers/usb/serial/ftdi_sio.ko

Make sure you are root.

(although, I use modprobe now thanks to jott and KotCzarny)

Re: Can someone please help me install a kernel module?

I'll put the module wherever you think I should (hey . . . watch it!).

Where is the best place to install it and what is the syntax used? Why doesn't D-rock's code dir start at root?

Re: Can someone please help me install a kernel module?

mkdir /lib/modules/`uname -r`
cd to wherever the ftdi_sio.ko is
mv ftdi_sio.ko /lib/modules/`uname -r`

xterm tells me

Code:

insmod: cannot insert 'usr/bin/ftdi_sio,ko': Unknown symbol in module (-1): No such file or directory

So, now two questions:
1) Where should I install the driver?
2) What is the proper code/syntax to install it?

Thanks for the help.

I feel like such a noob but. . .does the 'uname -r' mean I'm supposed to create a name and use it in place of uname? Do I append the chosen name with -r?

Thanks for the assistance.

That means you used the right command but another module may need inserting. Run the insmod again and run dmesg straight after and paste the last line here.

Re: Can someone please help me install a kernel module?

When I run dmesg, xterm spits out so much I can’t even scroll back to copy it all. This is what I could copy
