[Voyage-linux] usb disconnect

[Johann Wolfgang Goethe]

hello,

in november i asked for some help with my logitech z-5 loudspeakers
and voyage linux.
i had the problem that the usb device was disconnected from the bus. i
didn't use the alix 2c2 board since than. today i brought the board
and the speakers from my livingroom to work. since than it didn't
disconnect the usb speakers anymore. the only difference i can see is
that in my livingroot i had a basestation from my dect telefon near to
it.
could it be possible that the disconnect has something todo with the
dect phone next to it?

thank you very much in advance for your help.
