Here's what I get from my desktop

:~$ lsusb
Bus 006 Device 002: ID 8087:8000 Intel Corp. 
Bus 006 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 004 Device 004: ID 17cc:1001 Native Instruments 
Bus 004 Device 005: ID 0227:0227  
Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 002: ID 8087:8008 Intel Corp. 
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 04d9:1603 Holtek Semiconductor, Inc. Keyboard
Bus 001 Device 002: ID 046d:c018 Logitech, Inc. 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.

Exchange them and we can both have a poem, a tune, and a song.
