Troubleshooting
- Cards become unresponsive after inactivity [Show more]
Symptoms
- 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.
Cause
- 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.
Workarounds
Option A — 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).
Option B — 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:
- 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.
