Consider the following scenario:
- You have a computer that is running Windows 8.1, Windows RT 8.1, or Windows Server 2012 R2.
- You connect an SD card reader together with the hardware id VID_0BDA&PID_0307 to the computer through a USB port.
- Immediately after you wake the computer from sleep mode.
- The computer does not go to sleep but the SD card reader is idle for a long time without an SD card inserted.
