Use a metal needle, pin, or precision tweezers to bridge those two pins together.

You are most likely to encounter this controller in budget-friendly, no-name, or promotional flash drives. These are the drives often given away at trade shows, included as free gifts with other products, or sold on various online marketplaces at extremely low prices. While they offer good value for basic file transfer, they may not provide the same level of reliability or performance as premium drives from established brands.

Let’s unmask it.

This almost certainly stands for "Firmware" (sometimes abbreviated as FW). The presence of "F W" suggests that the OS is reporting a firmware-level problem. alcor micro unknown fa00 f w fa04

The is a standard, utilitarian USB card reader controller. While it may appear as "unknown" in system logs due to its generic OEM nature, it is a ubiquitous component responsible for reading flash memory cards in millions of computers. The FA04 string signifies the specific internal software version driving the hardware.

Type your specific VID and PID values into the configuration prompt. Click , then click Save/Install Drive .

Alcor Micro is a popular manufacturer of USB flash drive controllers (such as the AU6989SN series) and card readers. Use a metal needle, pin, or precision tweezers

Only if it’s causing issues (unlikely). If it annoys you in lsusb output, you can ignore it. No known power drain or kernel crashes linked to this device.

In 95% of cases, an Alcor controller with model FA00 does not physically exist in commercial product lines.

He recognized the name Alcor Micro—generic, mass-produced controllers used in millions of cheap drives. But "FA00" was a ghost. According to every tech forum he checked, a controller with that ID didn’t officially exist

Look for an MPTool package that matches the generation of your NAND memory chip. For drives showing Unknown [FA00] , versions like or newer often have the best success rates with late-model AU6989 controllers.
