This article covers everything you need to know about this specific chipset: what it is, why it fails, the "updated" firmware mystery, how to fix common errors, and where to find legitimate drivers in 2024-2025.

Step 1: Driver Preparation (Critical)

Windows will try to use its generic driver for the FA00 device. This will block AlcorMP.

Download Zadig or Alcor's InfUpdater.
Force the FA00 device to use the libusb-win32 driver or the specific Alcor driver included with AlcorMP.

✅ Step 2 — Install the correct driver

Try these sources:

Alcor Micro official — though they rarely provide public drivers.
Your PC/laptop manufacturer’s support site (if it’s a built-in reader). Notes: This update addresses the previous "unknown" device
Driver from generic card reader packs — sometimes the Microsoft CCID driver works.
- Go to Device Manager → Update driver → Browse → Let me pick → Smart card readers → Microsoft Usbccid Smartcard Reader (WUDF).
Gemalto / Safenet drivers — if this is for an eToken or ID card reader.

Overview — Alcor Micro “Unknown FA00 F W 3613 Updated”

Likely topic: Device identification string from Windows Device Manager for an Alcor Micro USB device (vendor Alcor Micro — often USB card readers, flash controllers). "Unknown" plus a hardware ID like FA00, F W 3613 suggests Windows labeled a device without a matching driver; "updated" implies searching for an updated driver or firmware.

Step 3: The Unlock Sequence

Because the firmware is 3613, the controller is likely password-locked in production.

Open the UnlockerAlcor.exe tool.
It should detect the FA00 device. Click "Unlock". You will see "Unlock Success".
Minimize the unlocker but keep it running.
