Martin,
thanks for your valuable comments. I agree not to upgrade anything once its
stable - I made a backup, so it was a kind of safe try... :)
And after raspi reboot - does it ALWAYS find the controller? My main
problem that mine is only sometimes, especially nowadays :( Syslog says it
has not enough power. While I'm using a 2A power supply. I need to play a
lot (unplug the bus, plug in USB, reboot, etc) to make it recognised /
work, and after a reboot I can start again...
I'm using USB9097 bought on pcsensor.com
