Cards become unresponsive after inactivity
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.

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.

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.
