You connect a USB audio device to a computer that is running Windows Vista Service Pack 1 (SP1) or Windows Server 2008. However, the audio device does not function correctly. When you examine the audio device in Device Manager, you see a yellow exclamation mark (!) next to the audio device. Additionally, the Device status area displays the following error message:

This device cannot start. (Code 10)

Note: This problem does not occur in the original version of Windows Vista.

You install Windows Vista before you update the basic input/output system (BIOS) to a Trusted Computing Group (TCG)-compliant version. If you do this, the Trusted Platform Module (TPM) 1.2 device driver (Tpm.sys) is not loaded. Additionally, a yellow exclamation point (!) appears next to the TPM 1.2 device in Device Manager.

Note: The TPM 1.2 device remains in this state even after you update the BIOS to a TCG-compliant version.

Consider the following scenario:

• You are running a Windows Vista-based portable computer from a docking station.
• The computer has a USB device connected to it.
• You put the computer into standby (S3).
• You resume the computer from standby.

In this scenario, a yellow exclamation mark (!) may appear next to the USB device in Device Manager. This problem may occur if the status of the docked portable computer is changed when the system is in standby.

Consider the following scenario. You have a PCI multiport serial adapter from Connect Tech, Inc. installed on a Windows Vista-based computer. You have a device connected to this PCI multiport serial adapter. In this scenario, a black exclamation point (!) on a yellow field appears next to the device in Device Manager.

Note: An exclamation point in Device Manager typically means that either the device or the device driver is installed incorrectly. Or, the device or the device driver is not working correctly.
