[linux-audio-user] My Edirol UA-20 arrived, but now I have a big problem!

[Frank Barknecht]

Hallo,

my Edirol UA-20 USB audio device has arrived, and I also got it to
work: It was almost plug and play. But now I have a serious problem,
and that is noise when moving the mouse. I'm at loss what to do.
Everytime I move the pointer with mouse or touchpad on my Acer
Travelmade, the UA-20 produces nasty screetching, crackling and
scratching. This doesn't happen, when I unplug the power supply. The
UA-20 gets its power from the USB-port, so I suspect that this creates
the conflicts. 

Does anyone have an idea how to get rid of this noise? Or should I
send back the USB device?

Thanks for any help...

ciao
