[Cpia2-development] cpia2 Unexpected error: -71 using qx5view

[Anthony T. <an...@un...>]

I'm trying to get the Digital Blue QX5 Microscope working with qx5view.

The lights cannot be controlled. When I press a button to control the
lights I get this message in /var/log/messages:
  cpia2: Control message failed, err val = -71 

Also, the video device /dev/video0 is removed and then qx5view no longer
shows active video, then /dev/video1 gets created.

I am using the cpia2 module that comes with the Debian compiled kernel:
 2.6.18-4-686 #1 SMP Mon Mar 26 17:17:36 UTC 2007 i686 GNU/Linux

I am using the qx5view from the CVS with most files dated May 19 2005 and
frontend.c at Oct 5 2005.

Is there any testing I can do to narrow down the problem?

Cheers,
Anthony
