In addition to your USB observations, I get kernel panics if I hot swap video connections while in Panther sleep. I stuck with 0S 9 until only 6 months ago, and had no such problems. The Panther workaround is to hot swap in awake mode rather than while sleeping. But as a mobile PB/iB user, who ports back-and-forth between external devices at least four times a day, I find this "avoid sleep" approach a fundamental violation of a mobile life/work style. Before I put my machine to sleep, I now have to stop and think about whether I will move it in the near future, and just in case, disengage all devices before sleeping -- and then reawaken it before re-engaging devices -- ridiculous. Someone might suggest just don't put the machine to sleep, but I believe the longevity of our laptops is enhanced by giving them a break from the heat buildup and incessant fan activity if left running. This is the one area I miss OS 9 the most. >> On 2/11/04 9:22 PM, "Jack Rodgers" <jackrodgers at earthlink.net> wrote: >> So, I think this confirms the problem we are experiencing with sleep >> while usb devices are connected or disconnected.
