Usb Vid-214b Amp-pid-7250 Amp-rev-0100 May 2026

When a computer encounters VID: 214B and PID: 7250, it is almost certainly communicating with a flash memory storage device.

More specifically, this ID pair is frequently associated with Toshiba TransMemory USB sticks or generic flash drives utilizing Toshiba memory controllers. Toshiba (now Kioxia) has long been a dominant player in NAND flash memory.

Common Scenarios for this ID:

This forces Windows to use its native USB Mass Storage driver.

For rare cases involving REV-0100 chips, Huaxu released a firmware update tool that forces the chip into a compliant mode. Use only if the device is unusable. usb vid-214b amp-pid-7250 amp-rev-0100

After extensive cross-referencing with open-source USB ID databases (like usb-ids from the Linux kernel) and vendor driver packs, the manufacturer behind VID_214B is Huaxu Electronics (also referred to as Huaxu Technology or generic Chinese IC designers).

The specific product for PID_7250 with REV_0100 is almost always one of the following: When a computer encounters VID: 214B and PID:

Why the confusion? Huaxu designs generic controller chips that OEMs purchase and integrate into various products. However, the REV-0100 string strongly suggests it is the initial hardware revision of their popular USB 2.0 to ATAPI bridge chip, which is primarily used for optical drives.
