Consider the following scenario:
- You have a computer that is running Windows Vista Service Pack 1 (SP1) or Windows Vista Service Pack 2 (SP2).
- That computer uses internal eHome Infrared Receiver.
- You resume the computer from hibernation.
In this scenario, a Windows Media Center remote control does not work. Additionally, you cannot find the eHome Infrared Receiver item in Device Manager. Instead, you find an Unknown device under Universal Serial Bus controllers. This issue also occurs when a Windows Vista-based computer changes from standby to hibernation when the hybrid sleep feature is enabled.
