| !Cards become unresponsive after inactivity
| |
| |-
| |
| |
| |
| '''<u>Symptoms</u>'''
| |
| * CCA shows as ''connected''.
| |
| * Company cards become unresponsive or show communication errors after a period of inactivity.
| |
| * Restarting the '''CCA Windows service''' restores functionality temporarily.
| |
| | |
| '''<u>Cause</u>'''
| |
| * Windows '''USB selective suspend''' may put idle USB ports into a low power state.
| |
| * USB smart card readers do not always recover correctly when the port resumes.
| |
| * As a result, CCA loses communication with the reader.
| |
| | |
| '''<u>Workarounds</u>''' <br>
| |
| '''<big>Option A</big> — Disable USB selective suspend (recommended)'''
| |
| * Control Panel → Hardware and Sound → Power Options
| |
| * Change plan settings → Change advanced power settings
| |
| * USB settings → USB selective suspend setting → '''Disabled'''.
| |
| * Apply for Plugged in (and On battery, if applicable).
| |
| | |
| '''<big>Option B</big> — Disable USB power management per device'''
| |
| * Open '''Device Manager'''.
| |
| * Expand '''Universal Serial Bus controllers'''.
| |
| * For each '''USB Root Hub''':
| |
| ** Right click → Properties → Power Management.
| |
| ** Uncheck '''Allow''' the computer to turn off this device to save power.
| |
| | |
| '''Notes:'''<br>
| |
| * This is a '''Windows power management behavior''', not a CCA defect.
| |
| * The issue is more likely to occur on non‑dedicated PCs with active power‑saving settings.
| |
| * For dedicated CCA hosts, '''Option A''' is usually the simplest solution.
