[SOLVED] CEC issue "configuration updated"

[ambro72]

I have a similar problem.
My xbian (alpha 5) is connected to a Samsung TV.
Never issue related to CEC. I got the message "cec connected to TV"
All worked fine before 3 days ago.

Now I get the message "cec pulse eight, configuration updated" and nothing works on my remote control.
I tried to reset tv configs, and check that CEC is enabled on my tv and on my xbian-config. All seems ok.

I tried

Terminal

# cec-config
=== USB-CEC Adapter Configuration ===

opening a connection to the CEC adapter...

Failed to power on the TV, or the TV does not respond properly
