Can't get my camera working: sn9c20x: Unknown symbol video_ioctl2. (0c45:612a Microdia; Ubuntu 8.04)

[Alaric]

Hello,

I have been trying to make my webcam work (0c45:612a Microdia; Ubuntu
8.04).

1. installed Git and downloaded the source code. Had some trouble
because I lacked curl but installed this following instructions in one
of the discussions and things seemed to go okay.

2. did 'apt-get install kernel-package linux-headers build-essential
libv4l'.

3. didn't understand anything in 'Setting up the compilation
environment' so I left that alone.

4. this is what my terminal says when I do the make command, which I
guess looks okay, though it says 'ctags: Command not found':

alarichall@Branwen:~/microdia$ make
make -C /lib/modules/2.6.24-23-generic/build SUBDIRS=/home/alarichall/
microdia modules
make[1]: Entering directory `/usr/src/linux-headers-2.6.24-23-generic'
Building modules, stage 2.
MODPOST 1 modules
make[1]: Leaving directory `/usr/src/linux-headers-2.6.24-23-generic'
make: ctags: Command not found
make: *** [ctags] Error 127

5. then I do 'sudo insmod ./sn9c20x.ko'. At first I had the error
'insmod: error inserting 'sn9c20x.ko': -1 Unknown symbol in module'
but I followed the instructions listed under troubleshooting and I
haven't had that error message again.

6. This is what I now see when I do 'sudo insmod ./sn9c20x.ko':

alarichall@Branwen:~/microdia$ sudo insmod ./sn9c20x.ko
insmod: error inserting './sn9c20x.ko': -1 File exists

I type 'stdout' and get:

alarichall@Branwen:~/microdia$ stdout
bash: stdout: command not found

When I type 'dmesg' I get lots of stuff ending with:

I've looked around the discussions but I can't work out where to go
from here--I'd appreciate any advice. Thanks!

To reload the driver (after insterting videodev, ...) use this:
# rmmod sn9c20x
#insmod sn9c20x.ko

Hopefully everthing works afterwards.
