Second attempt with a em28xx on Raspberry Pi... I'm so fucking bored of this not working I decided to do it again.
This is largely based on the first attempt...
http://bufobufomagic.blogspot.co.uk/2012/07/make-disk-image-mac-diskutil-list-sudo.html
build SD card (on a mac) and, probably, make it work
diskutil list
sudo diskutil unmountDisk /dev/disk1
dd if=/Users/michael/Desktop/RaspberryPi/Images/archlinux-hf-2012-09-18.img of=/dev/disk1 bs=1m
muck about with partitions - i expand the arch linux partition to 4Gb and call the remainder of the drive fat32.
fiddle with boot partition memory elves - rename original start elf and copy the 240 start elf as start.elf
then insert card, boot RPi and watch the LEDs dance about while you find it on the network.
mine was 85...
ssh 192.168.1.85 -l root (password root)
if this isn't your first time round the loop you might get a load of key verification errors, so do
ssh-keygen -R 192.168.1.85
and try again.
it is plugged in, right?
set up stuffs
swapdisk-u-like
mkdir -p /var/cache/swap/
dd if=/dev/zero of=/var/cache/swap/swapfile bs=1M count=1024
chmod 0600 /var/cache/swap/swapfile
mkswap /var/cache/swap/swapfile
swapon /var/cache/swap/swapfile
echo "/var/cache/swap/swapfile none swap sw 0 0" >> /etc/fstab
...otherwise just remember to check it's on before you make the kernel.
upgradings
// if you like progress bars, this will give you the horn.
pacman -Syuand open a bottle of red wine.
install stuff
// because you want stuff
pacman -S ffmpeg motion git base-devel python2
Shall we reboot? Wouldn't be a bad idea. It will be nice to see it boot in a working state one more time...
do a kernel
get the kernel source
// are you doing this for fun? - because it isn't.
cd /home
git clone --depth 1 https://github.com/raspberrypi/linux.git
cd linux
zcat /proc/config.gz > .config
make menuconfig
( it appears i2c and em28xx stuff is all there now, but you can have a look for yourself)
muck about with the kernel

I suspect this is something to do with the wrong card id...

It's supposedly a kworld 2800USB, so i'll try 8
modprobe -r em28xx
modprobe em28xx card=8
doesn't work, hangs on Resizing pre_capture buffer to 1 items - which i think is an improvement. card=19 doesn't work either, same error - although i have a feeling that's how it has turned up in the past.
New drivers?
cd /homemkdir stuff
wget http://aur.archlinux.org/packages/pe/perl-proc-processtable/perl-proc-processtable.tar.gz
wget http://aur.archlinux.org/packages/pe/perl-proc-processtable/PKGBUILD
makepkg --asroot -s
pacman -U perl-proc-processtable-0.45-3-any.pkg.tar.xz
pacman -S patchutils
cd /home
git clone git://linuxtv.org/media_build.git
cd media_build
./build
the build failed on smiapp-core.c
at this point I make menuconfig and start removing stuff
then try to make it again.
make install
this seemed to work now
reboot
but the driver still doesn't. I'm giving up on this board for a while.
