Can you repeat your tests?  I never announced the cxusb tree for testing,
and you tested an old copy.

There was a bug in that version, the new version is posted now.

After hearing successful test results using changeset 56b3acf44eae , I
will ask Mauro to merge it.

56b3acf44eae works for me.  Please feel free to merge it.

Also, the i2c read failed messages that I was getting appear to go away
once I plug in the IR cable into this card (I don't use IR on my
mythbackend).    Can I suggest the following additional patch to stop the
logs filling up with noise in this scenario.  This makes the logging
consistent with the rest of the driver.

Cheers

au-specific firmware should no longer be necessary.

Hi Folks,

I've been successfully using the experimental v4l-dvb tree DVICO Dual
Digital 4 drivers for a number of months.  Today I decided to try an
use
the official 2.6.26 kernel drivers, but they are triggering an OOPS at
firmware load time (see below).  Can someone please confirm if the
xc3028-dvico-au-01.fw  firmware is still compatible with 2.6.26? or
are
there any other known issues in this space?

Thanks

-Rob
