ezCap startup options

Hi,

I have an old unbranded ezCap USB device and an old wifi infra red
webcam and with some time on my hands I wanted to hook it up to a
Pi/raspian to watch my swallows nesting :-) 

It has taken me a while to get it to automatically load the module and I
am not sure I have done it the right way. There are various odd musings
on the interwebs and I saw this on the mailing list:

https://www.spinics.net/lists/linux-media/msg63928.html

This seems to get it to load on start up. 

My question is, is there a better/cleaner way?

/etc/modprode.d/em28xxoptions.conf
options em28xx card=9

rc.local:
echo eb1a 5124 | tee /sys/bus/usb/drivers/em28xx/new_id

card 64 throws an i2c error as below but seems to work.

(I have not tested S-Video or sound)

I did try a udev rule but that didn't seem to work.

Any suggestions appreciated.
