'New Hardware Found' Starting Computer with CardBus Adapter Inserted (300568)

SYMPTOMS

When you start your portable Windows Millennium Edition (Me)-based computer with a CardBus adapter inserted, the CardBus adapter may not be recognized, and you may receive the following message or one that is similar to it:

New Hardware Found
PCI Ethernet Controller
Windows has found new hardware and is installing the software for it.

When this problem occurs, the CardBus adapter may not function correctly until you eject and then reinsert the adapter.

CAUSE

There is a timing issue that may occur on some computers with specific processor types and speeds, in conjunction with certain CardBus adapters that have specific timing requirements for initializing or resetting the adapter.

This problem occurs when the PCCard device driver (Pccard.vxd) resets the PCCard socket. If the adapter in the socket is a CardBus type adapter, Pccard.vxd immediately performs a second reset of the socket. Depending on the hardware combination, this second reset may occur during a time when the adapter is not stable, resulting in an incomplete reset of the adapter. When this occurs, the card's registers will not return correct values, so the card will not be enumerated correctly and will not function normally.
