what makes you think it's the cable? do you see the usb icons changing, or have you only diagnosed it through the drop in the audio? it could be software issues. i found rocksmith very unstable and laggy on a lower-end laptop without a decent graphics card, so built a little desktop to run it, and can run at full graphics now.
@@Palpo considering we are in Germany, your concerns are legally valid. my experience so far is that i have downloaded about 1400 from the site and no one has bothered me. i wouldn't dare grab a movie or commercial album this way, though.
