psalter,
I have just reproduced the fix you described in post #17. I am now able
to use my Dvico Fusion Dual Digital 4 again!
I installed the packages
linux-image-generic-lts-vivid
linux-headers-generic-lts-vivid
The net result is
linux-image-generic-3.19.0-49-generic
Sounds like a good solution.

#define MAX_XFER_SIZE 80
to
#define MAX_XFER_SIZE 61
is enough to fix the problem.
I have confirmed that with this change the firmware loads and I am able
to watch TV using me-tv.

Furhter testing has revealed that the DViCO FusionHDTV tuners don't work
with mythtv or with me-tv (running upstream 3.14 kernel). The Budget-CI
card is working OK with me-tv.
It appears that the firmware loading problems are real.
