Why doesn’t the reader light come back on after my computer comes out of hibernate/sleep mode?


Article Summary

The most likely cause is that the USB Controller on your system turns off automatically after a certain period of inactivity. If you are using Windows XP, follow the instructions below to disable power save option for the USB Controller on your computer:

  • Open the Windows Control Panel and double click on the System.
  • Click on the Hardware tab and then press the Device Manager button.
  • Double click on the Universal Serial Bus Controllers.
  • Right click on the USB Root Hub.
  • Go to Power Management tab and uncheck the “Allow the computer to turn off this device to save power”.
  • If the above procedure doesn’t resolve this issue, try connecting the reader through a self-powered USB hub
