Optical Wheel Mouse Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub If you look at the names first then follow back along to the Bus and Device you ideally want your audio system on its own Bus. In my case that's the native instruments (a KA6) which is the only device on Bus 004 apart from the hub itself. Further down I have a keyboard and mouse both sharing Bus 001. Depending on the quality of your laptop, it's possible they put all three USB sockets on the same Bus, or alternatively share with some internal systems. On my desktop there are two anonymous Intel ones, but I'm not concerned as they are away from everything else. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.
