Hello, I have a problem. My mouse and printer are connected to the usb hub of my MS Natural Keyboard Pro that itself is connected via usb to the computer. Everything works, but the side buttons of my MS Intellimouse Optical 1.1A do not work as i wish (e.g. browse forward or backward in browser history). With Knoppix 3.3 and some modification to XF86Config they do their job. I got hints from: http://groups.google.com/groups?hl=de&lr=&ie=UTF-8&oe=UTF-8&frame=right&th=e60899840351e001&seekm=nrmq1b.6e.ln%40nntp2.linuxuser.org.uk#link16 Is there anyone who can help me.
