Usb Vid-214b Amp-pid-7250 Amp-rev-0100 File
No driver installation is usually needed. If the device is not recognized:
A PID of is frequently associated with USB Flash Drives or Mass Storage Controllers . Specifically, in the context of VID 214B, this identifier often points to a generic USB flash drive or a memory card reader controller. It is commonly seen in "OEM" (Original Equipment Manufacturer) flash drives—promotional items, unbranded memory sticks, or internal card readers found in laptops.
At first glance, it looks like a cryptic alien language. But this code is actually a digital ID card for a piece of hardware you might have lying around. Let’s break down what it is, why it matters, and what to do if you need drivers for it. usb vid-214b amp-pid-7250 amp-rev-0100
When programming an Arduino or ESP32 using this chip, note that the REV-0100 may require setting a longer reset delay ( DTR pulsing) compared to newer revisions.
This chip is . You have two options:
If you have landed on this page, you have likely opened your Windows Device Manager, Linux dmesg log, or macOS System Information tool, and been confronted by the cryptic string: . At first glance, it looks like a random assortment of numbers and letters. However, this string is a critical identifier for a specific piece of hardware.
: 214B This is a unique code assigned by the USB Implementers Forum (USB-IF) to a specific manufacturer. In this case, 214B belongs to Huaguang (or sometimes labeled under generic USB bridge chips from Chinese vendors) . More precisely, VID 214B is often associated with Nuvoton Technology Corporation (formerly Winbond) or generic USB-to-serial bridge controllers manufactured under license. No driver installation is usually needed
Integrated into many unbranded or "white-label" USB 2.0 hubs, such as the Ginzzu GR-315UB USB Switches: Used in KVM-style peripheral switches like the AIMOS AM-UK404 (4-in-4-out USB switch). Combo Adapters:
| Issue | Symptom | Solution | |-------|---------|----------| | Driver conflict with older FTDI drivers | Device shows as “FT232R” despite VID 214B | Uninstall FTDI drivers via Zadig or USBDeview | | Code 10 in Device Manager (Windows) | “This device cannot start” | Uninstall device, rescan, install CH340 driver v3.5 or use legacy v3.4 | | Baud rate errors above 115200 | Garbled serial data | Reduce to 9600 or 115200; REV-0100 may miss high speeds | | macOS no device after sleep | Disconnected virtual port | Unplug/replug USB cable | | Linux losing connection under heavy load | “ch341-uart: ttyUSB0: ch341_control_out failed” | Add usbcore.autosuspend=-1 to kernel boot parameters | It is commonly seen in "OEM" (Original Equipment
A VID of (Hexadecimal) converts to 8523 in Decimal. In the world of generic USB peripherals, this Vendor ID is widely associated with Hangzhou Hikvision Digital Technology Co., Ltd. or generic flash memory controller manufacturers based in China that utilize Hikvision chipsets or cloning software.
