Just did the 10.4.8 update, and it has broken my Logitech USB S530 Keyboard and Mouse. They are now wholly unresponsive unless, after a boot up, I unplug and then replug the USB connector for their receiver. While annoying, this is not fatal, but it *IS* annoying. Is anyone else having this problem? Any cures? Right now, the receiver for this keyboard, mouse is plugged in via a USB hub on my desktop. I may try connecting it direct from my PowerMac G5.
