Since XP, the Windows operating system has come with a feature called USB Selective Suspend. This allows the system to turn off specific USB ports without affecting the other USB ports. This is supposed to save power by closing down ports that are only used intermittently. However, sometimes the port does not get turned back on when it is needed. On a desktop or other system where this type of power saving is not crucial, consider disabling this feature if you are experiencing USB connection problems.
Possible solution (will have to be tested):
1. Open Control Panel
2. Go to: Hardware and Sound->Power Options
3. Find your preferred power plan and click “Change plan settings”
4. Click “Change advanced power settings”
5. A dialog box similar to the example in the graphic below will open
6. Find the entry “USB settings” and expand it
7. Expand the entry “USB selective suspend setting”
8. Use the drop-down menu to disable or re-enable the setting as shown in the graphic below
9. Click "OK"
