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
Thanks to the details above I was able to get my Dvico Fusion Dual Digital 4
working on Mythbuntu Trusty 14.04.3 . The problem was solved at kernel 3.19.
Problem is related to cxusb.c where the #define MAX_XFER_SIZE 80 was changed
from 64 to 80. Details of change are at LinuxTV.org:
Ok, I've changed my default boot kernel to come back to the kernel
3.2.0.29 (Ubuntu 12.04.1 LTS april 2017) and it works fine, it's less
expensive than change the card ;-)
The problem is since the kernel 3.13 (Ubuntu 12.04.5)
Thanks for your help.

Sounds like a good solution.

Hi,
How do fix this issue ?
I've the same error :
3242.308051] xc2028 0-0061: i2c output error: rc = -95 (should be 64)
[ 3242.308055] xc2028 0-0061: -95 returned from send

[ 3242.352112] xc2028 1-0061: Loading firmware for
It turns out that a much deeper fix is necessary, and I have not created
it. My current solution is to blacklist the driver. I plan to replace the card.
Alternatively, you could big the guys at Linux tv.org, the ones who write
the drivers in the first place. Launched doesn't seem to be where
After further work and testing, I have found that changing
drivers/media/tuners/tuner-xc2028.c:28
#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.

Unfortunately, that change had no effect. The errors found in the log
previously still occur, but they are delayed from the initially
successful output posted previously. More investigation is required.

I see the same firmware loading issue. I assumed the problem was in
tuner_xc2028, as I don't see any related messages in dmesg after the
firmware blob fails to load:

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.
