Do you mean the PointNix Intra-Oral USB camera? I guess it's possible
they both have the same eeprom hash value. I can find out if perhaps
the i2c hash is better (I haven't looked at that code though).
I added the PointNix camera support, so I can probably find out the
i2c hash if that helps us.
I'm just concerned about cases where we are poking the GPIOs. This
could destroy hardware if abused by users that don't know any better.
