It simply accepts no input after I come back to my machine. I use BIOS (firmware update 1.1 for intel mac mini) emulation and kernel 2.6.15.2. When I disconnect it, it works like charm again. Has anyone an idea or sees the same effect? I had running 2.6.15.2 two weeks without rebooting running on my mac mini and did not experience such problems. My only idea is that it has something todo with the firmware upgrade for the bios comp. layer. Does anybody sees such effects in here who has firmware update 1.1 installed? My solution so far is to unplug my keyboard and put it in after 3 seconds. After that it works again. The mouse is working all the time. I use a SUN Type 6 USB keyboard which is shipped with SunRays. I also tried to use another SunRay keyboard which doesn't change the problem.
