Your system may be set to switch off the USB controllers when you’re not using them. This is a power-saving feature that is useful in extending your battery life.

  • Type “devmgmt.msc” (no quotes) inside the Run dialog box, then click “OK.”

  • Expand the contents of the “Universal Serial Bus Controllers” category.

  • Go to the “Power Management” tab.

  • Click “OK” to save the changes.
