This article describes a situation that may cause computers with USB Adapter Cards to stop responding and provides a workaround.

After installing the USB Adapter Card Support software from Apple, the PowerBook occasionally stops responding when a USB CardBus (PCMCIA style) card is installed.

Solution

PowerBook G3 computers, with CardBus cards, stop responding with USB Adapter Card Support installed if processor cycling is enabled. Use the Energy Saver control panel to turn off processor cycling for both battery and power adapter operation.
