Problem:
When I swipe a card through my USB card reader, I hear it beep, but I don't get data into my app or Notepad. This happens after the system sits idle for a while. I can unplug and re-plugin the reader to get it working again.
Solution:
A. This may be due to the USB ports power saving is triggered. If so, you can follow the steps below to disable the USB Selective Suspend on your PC.
- Got to Control Panel>System & Security (if Windows 10)>Power Options>Change Plan Settings for the currently selected power plan (see below for Vista screen shots), for Win 7 and 10, the link is on the far right side of each plan option
- Click the Change advanced power setting link:
For Vista, select the Disabled option under USB Settings>USB Selective suspend setting
For Win 7 PC and Win 10, select the "Disabled" under USB Settings>USB Selective suspend setting>Plugged In
