I would suggest to modify all drivers only after 2.4 is released. It will
be then part of generic USB video library (which would include
load/unload, open/read/mmap/close, ioctl, USB data pump with color
transformations done in read/ioctl (V4L client) context etc. etc.)
Such library could be a module on its own, and it would greatly simplify
all video device drivers (they only need to provide callbacks to do
things). It will also increase reliability of all drivers because more
code will be shared. But it is also a BIG change.
This will hopefully address V4L2 integration as well.
Thanks,
Dmitri
