SYMPTOMS

You connect a USB composite device that supports consumer infrared (CIR) to a computer that is running Windows 7. However, the driver for this device is installed incorrectly. Therefore, the device does not work correctly. Additionally, a yellow exclamation mark is displayed next to the device when you view it in Device Manager.

For example, when you connect a smart card reader that supports CIR to the computer, the smart card reader does not work.

CAUSE

This issue occurs because the USB CIRClass driver is installed instead of the USB common class generic parent driver (Usbccgp.sys).
