I recently picked up a 16 port DVR card from China which uses two
CX25821 chips. I compiled the staging driver for it and was able to
load it successfully with kernel 2.6.32-rc2. But I can't find any /dev
devices to get at the inputs. I created a character device with a
major/minor of 81/0 but am unable to open it.
What device major/minor should I be using or is the driver that far
yet? Do I need to add a card definition to get this going?
Again, I'm using kernel 2.6.32-rc2 with the CX25821 staging module.

We're planning to do some work inside KernelLabs on that particular
driver. We have access to hardware and are looking to stabilize and
improve the overall quality of the driver to a commercial production
grade. I don't have any timescales as this is currently and unfunded
project but you're not alone, the driver does need some major
improvements.

Mmm, any links to a reasonably priced CX25821 capture cards?
