Too Good To Last
Mar. 30th, 2002 12:03 pmI'm really perplexed by this failure mode. It'll work fine for about 16 hours, then lose track of the USB ports; then you can reset it with a reboot; then you're back into the mode where you get about a minute out of it every time you switch back to it.
Possibly something's being triggered by the Energy Saver? But I don't understand why I wouldn't get another long chunk of OK time after a reboot, in that case. USB is supposed to be fairly stateless, and this feels pretty stateful.
Oh well. Next test is a direct connect and more patience -- see what happens when the Energy Saver kicks in then, see if there's still breakage after the first 16 hours, and so on. I still kind of think it's about the switch. If I physically unplug the switch and plug it back into the Mac, the USB seems to work for a while longer. Just switching to the PC and back gives me only a minute or so of functionality. I wonder if the switch isn't giving out some kind of trickle "I'm connected" signal that messes things up?
