[linux-dvb] MT2266 I2C write failed, usb disconnet, WinTV Nova-TD stick, remote

[Bernhard Albers]

Hello everyone!

I recently installed mythbunut 7.10 and tried to get the WinTV Nova-TD
stick working with the latest v4l-sources (mercurial)

Output of lsusb:  ID 2040:9580 Hauppauge
Hauppauge Remote: A415-HPG-WE-A

When I start mythbuntu, I get the following error, after switching the
channels using the mythbuntu frontend (dmesg):

If I disable the remote sensor  in "/etc/modprobe.d/options" via
"options dvb_usb disable_rc_polling=1" this i2c failures do not seem to
occur.

Maybe it is a problem of the mainboard. It is an Asus m2a-vm hdmi
(amd690g chipset and ati x1250 onboard graphics) with the latest Bios
(1604).

Best regards

Interesting theory...
I'm seeing the same thing on a Biostar TA690G mainboard, which uses the same 
chipset. It works fine on my desktop machine though (VIA K8T800PRO chipset; 
ASUS A8V Deluxe) and on my ASUS Eee (can't remember off-hand what chipset that 
uses, an Intel one of some description IIRC).

Had some strange signal issues with the Nova-TD-Stick too - Tuner 0 worked 
fine, but Tuner 1 failed to lock onto the mux that carries FilmFour. Putting a 
6dB attenuator inline fixed that nicely -- seems the low-noise amplifier in 
the Microtune chip sets its level based on an average of the whole band it's 
tuned to. Lots of strong signals = low amplification = not much signal 
strength going into the DiBcom decoder/demux chip. Weaken some of the strong 
signals, and it's fine. Most peculiar.

I've already told it to Bernard but not yet in the list:
Notice that this one seems to be a known issue (even to windows people)
related to an incompatibility between 690g mainboard (more precisely
sb600 southbridge) and nova td stick. It seems that it causes usb
disconnect when the stick works in dual mode (always in linux) using
both tuners at the same time. People reported the problem can be solved
with a pci usb expansion or using the stick with another mainboard.
There is also a note about it in the linuxtv wiki (NOVA-TD Stick page).
It's interesting to note that both you and Bernard experienced the
problem even with just one tuner.
