Alcor Micro Unknown Fa00 F W Fa04 «2027»
Right now, Linux may not auto-load a driver. You can check:
dmesg | grep -i fa00
For a smart card reader:
Install pcscd and libccid:
sudo apt install pcscd libccid # Debian/Ubuntu
sudo pacman -S pcsc-tools ccid # Arch
Then run pcsc_scan. If it detects the reader, you’re good.
For a fingerprint reader:
You may need libfprint (though that’s more common with Synaptics or Goodix). Alcor fingerprint readers have poor Linux support.
Alcor Micro is a known Taiwanese chip designer. They make:
The 058f:fa00 USB vendor:product ID is not documented in the main Linux USB ID repository, which means it’s either:
From user reports across forums, this ID shows up most often on:

This specific identifier, "Alcor Micro Unknown FA00 F/W FA04," typically appears when a computer's operating system or a flash drive repair utility cannot properly identify a USB device's internal hardware. What It Means
The Controller: "Alcor Micro" refers to the manufacturer of the USB controller chip inside the device. These are common in many brands of USB flash drives and SD card readers.
Unknown FA00: This status suggests the flash drive's firmware is corrupted or the controller is in "test mode". Some experts suggest a controller model "FA00" doesn't officially exist and is likely a generic error code shown when the chip's real identity is masked by damage or bad firmware.
F/W FA04: This represents a specific firmware version. While Alcor Micro has released many firmware updates, finding "FA04" paired with "Unknown FA00" often indicates the device is using a non-standard or corrupted software layer. Common Causes
Firmware Corruption: The software that runs the USB drive has crashed, making the drive appear as "No Media" or with 0 bytes of capacity.
Fake or Refurbished Hardware: Alcor controllers are frequently used in "fake" high-capacity drives (e.g., a hacked 8GB drive sold as 2TB). When these fail, they often revert to this "Unknown" state.
Physical Damage: Electrical or mechanical failures can prevent the controller from reading the memory chip's unique ID (FID), leading to an "Unknown" identification. How to Address It alcor micro unknown fa00 f w fa04
Would you like help identifying the exact Alcor controller model or finding the right MPTool version for FA00 / FA04?
The Alcor Micro "Unknown [FA00]" error, often accompanied by "No Media" or "0 Byte" status, indicates a firmware or controller communication failure, frequently affecting counterfeit or cheap drives. Recovery involves using specialized MPTool or FC_MpTool utilities to re-flash the controller, often requiring specific, modified tool versions based on VID/PID data to successfully re-evaluate memory cells.

The string "Alcor Micro Unknown FA00 F/W FA04" is a diagnostic status often displayed by low-level USB recovery tools (such as AlcorMP or ChipGenius) when a flash drive using an Alcor Micro controller has failed. Understanding the Status
This specific readout indicates that the recovery software has partially communicated with the USB controller but cannot fully identify the hardware components. Alcor Micro : The manufacturer of the flash drive's controller chip. Unknown FA00
: This usually signifies that the software cannot find a matching controller ID in its database or that the controller is returning a generic error code (FA00).
: Refers to a specific firmware version or revision detected on the chip, which may be corrupted or incompatible with the current version of the repair tool. Common Causes Firmware Corruption
: The internal software that manages data on the chip has crashed, making the drive appear as "No Media" or with 0GB capacity. Hardware Failure
: Physical damage to the NAND memory chip or the controller often results in "Unknown" status because the controller cannot retrieve the Flash ID (FID). Incorrect Software Version
: Alcor Micro frequently updates its controllers, requiring a specific version of or FC MpTool to recognize and reflash them. Potential Solutions Check Hardware ID (VID/PID) : Use a tool like ChipGenius
to find the exact Vendor ID (VID) and Product ID (PID). Standard Alcor IDs are typically Manual Driver Installation : In AlcorMP, use the Right now, Linux may not auto-load a driver
button to manually add your specific VID/PID if the tool does not automatically detect the drive. Reflashing
: If the drive is detected but shows "Unknown FA00," you may need to download a "Modified Edition" of AlcorMP that includes updated flash lists for newer chips. : Flashing firmware is a "low-level" format that will permanently erase all data on the drive.

By following the troubleshooting steps outlined in this post, you should be able to resolve any issues related to the Alcor Micro Unknown FA00 F/W FA04 identifier. Happy troubleshooting!
This error typically occurs when an Alcor Micro USB controller (common in flash drives and card readers) has corrupted firmware or is a generic/fake drive that the computer cannot identify. Understanding the Error For a smart card reader: Install pcscd and
Unknown [FA00]: This is a generic status code returned by the controller when it fails to identify its model or flash memory chip (FID).
F/W FA04: This refers to the specific firmware version (or failure state) currently reported by the device.
Symptoms: The drive may show up as "No Media," "0-byte capacity," or "Disk is Write Protected". Potential Fixes
To recover the drive, you generally need a "Mass Production Tool" (MPTool) compatible with your specific hardware.
Identify the Real Chipset: Use a tool like ChipGenius or Flash Drive Information Extractor to find the actual Controller Part-Number and Flash ID (FID). Download the Correct Utility:
Visit specialized databases like USBDev.ru to find the version of AlcorMP that supports your specific FID.
For Transcend-branded drives, use the Transcend Online Recovery Tool which often resolves these "FA00" errors automatically. Run AlcorMP: Open the tool before plugging in the drive.
If the drive is not detected, use the "Driver" button in the tool to manually add your device’s VID/PID (Vendor and Product ID).
Perform a "High Level Format" or "Full Scan" to re-flash the firmware.
Warning: Re-flashing firmware will permanently erase all data on the drive. If the FID shows a nonsensical value like 898989898989, the hardware likely has a physical electrical failure and cannot be fixed.
Do you have the VID/PID or the Flash ID from a tool like ChipGenius to help narrow down the right software? Alcor Micro - USBDev.ru
Let’s break the keyword down piece by piece.
In summary: The keyword describes a USB storage device with an Alcor Micro controller whose firmware has failed or is inaccessible, causing Windows to label it as an unknown device with error status FA00/FA04.
In some Alcor tools, 04 means 4-plane flash or 4KB page mode.
The keyword phrase itself tells a story. Let’s break it down:
When users search for FA00 or FA04 alongside "Alcor Micro," they are usually looking at the Hardware Ids in Device Manager (under Details tab), which might look like USB\VID_058F&PID_FA00 or USB\VID_058F&PID_FA04.
Important: The standard Alcor Micro vendor ID is
VID_058F. A PID ofFA00orFA04is not a normal, functional device ID. A healthy Alcor card reader might showPID_6366orPID_9370. SeeingFA00orFA04means the device is in a "pre-boot" or "panic" state.
