Alcor Micro Unknown Fa00 F W 3613 Updated ^new^ [Must Read]

The Linux kernel provides native support for Alcor controllers, particularly the USB mass storage driver. However, the specific FA00 identifier does not require separate kernel module configuration beyond standard USB storage handling.

While keeping those two pins bridged, plug the device into the computer's USB port.

Why? Because the is a relatively late firmware revision for this chip family. Most public drivers available on the internet (versions 1.0.6.0, 1.0.19.0, etc.) were written for older firmware like 3510 or 3520. When Windows queries the chip and receives "FA00 F/W 3613," the older driver's INF file does not contain a matching hardware ID. Hence, "Unknown Device." alcor micro unknown fa00 f w 3613 updated

The key to success is finding an AlcorMP version that supports your specific combination of controller and flash memory. You may need to try several versions. Common versions mentioned in forums include:

Anatomy of the Error: What Do "Unknown [FA00]" and "F/W 3613" Mean? The Linux kernel provides native support for Alcor

This report details the identification and restoration process for Alcor Micro USB flash drives exhibiting the "Unknown" status with firmware (F/W) version and chip code

| Identifier | Meaning | Typical Solution | |:---|:---|:---| | Alcor Micro | Controller manufacturer (Taiwanese fabless IC company) | Use Alcor‑specific tools | | Unknown [FA00] | Controller model not auto‑detected; hardware ID suggests AU6989SN family | Try multiple AlcorMP versions | | F/W 3613 | Firmware version 3613 on the controller | Match tool version to firmware range (v16.x or newer recommended) | | VID 058F PID 6387 | Standard USB IDs for Alcor mass‑storage devices | Confirms device is an Alcor flash drive | | AlcGener.sys | Driver for Alcor Micro Smart Card Reader | Update driver manually from laptop vendor | | PCI\VEN_1AEA&DEV_6625 | Hardware ID for internal Alcor PCIe card reader | Manual driver installation from vendor driver package | When Windows queries the chip and receives "FA00

: If the tool still doesn't see the drive, you may need to manually enter "Test Mode" by shorting specific pins on the controller chip (only recommended for advanced users). Change VID/PID : Sometimes changing the ID using the Alcor Change PID/VID Rework utility can help the software recognize the hardware. : Always use a USB 2.0 port

: Run the "Start" or "Flash" process. This will overwrite the corrupted 3613 firmware with a stable update and re-partition the drive.

The “Unknown FA00 F/W 3613” message almost always relates to a USB flash drive. However, Alcor Micro controllers also appear in integrated media card readers inside many laptops, especially HP and Lenovo models. Driver problems with these readers are extremely common and produce similar “unknown device” entries in Device Manager.
