  • 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:
