Resolution
1. Ensure that your device is properly connected to your PC/notebook. Check that the device is working correctly using Device Manager.
2. Ensure that you are using a compatible socket. Many of devices are not tested with USB 3.0, and requires more transfer speed that USB 1.0/1.1 has.
3. If you are using Windows Vista or newer: Many of authentication devices has two sets of drivers:
-
Drivers downloaded via Windows Update service automatically. This drivers does not have any third party interfaces and is highly limited as to its functions.
-
Drivers distributed by authentication device producer.
Remove the drivers downloaded via Windows Update using Device Manager and install the drivers distributed by authentication device producer.
4. If you are using the drivers distributed by authentication device producer, check that third party services are started and working correctly. E.g. Authentec service may be set to “manual” by default.
Some of such driver software can contain test utilities. Ensure that device is working correctly using such third party test utilities.
