CardBus Device Not Enumerated with TI 14xx or 44xx CardBus Controllers

ID: Q233017

The information in this article applies to:

Microsoft Windows 98

SYMPTOMS

CardBus cards in computers with certain Texas Instruments (TI) CardBus controllers may not be enumerated, or may be disabled on power-up or when you resume the computer from Suspend mode.

This issue affects computers with the following TI CardBus controllers:

PCI1410
PCI1420
PCI1450
PCI1451
PCI4410
PCI4450

CAUSE

These controllers require a non-standard delay of up to 32 milliseconds during the transition from the D3 power state to the D0 power state before the CardBus "Socket Present" register reports an accurate device status. This behavior is not in compliance with PCI specifications, which require PCI devices to be ready and correctly reporting their status within 10 milliseconds of transitioning from D3 to D0.

RESOLUTION

To work around this problem if a CardBus device is not enumerated after power-up or when you resume the computer from Suspend mode, use any of the following methods:

Eject, and then reinsert the CardBus card.

In Control Panel, double-click the System icon, click the Device Manager tab, and then click Refresh.

If these methods do not cause the CardBus card to be re-enumerated, verify that you have the correct drivers installed for the CardBus controller in your computer. Contact your computer manufacturer if necessary for help with installing these drivers.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
