Hi Mark,
Just to let you know that the latest version of your driver (
ov511 1.50) works with this camara. Looking back in the archive this
device musy have changed, it used to use the CPiA driver. I still use
kernel 2.4.8 though (my laptop doesn't always come back from suspend with
any later 2.4 kernel) and had to make this change;

otherwise the snprintf was unresolved. With the driver that came with this
kernel the picture was very dark, the output during startup was;

Thanks!! BTW, I just bought this camera without really expecting
it to work. It was $29.99 from Fry's in Palo Alto and comes with a $20
mail-in rebate.
regards,
Stephen.
