Ub93 Driver Windows 10 ((full))

1. What is the UB93?

The UB93 is a USB 3.0 to HDMI/DVI/VGA external graphics adapter. It uses chipset technology from Fresco Logic (FL2000/FL200DX) or DisplayLink (depending on the clone). It adds an extra monitor via USB, without requiring an internal GPU port.

⚠️ Critical: Many UB93 adapters are counterfeit/clones using unlicensed chips. Genuine drivers from DisplayLink may not work. You likely need an alternative driver. ub93 driver windows 10

For CH340/CH341 (most UB93 devices)

Download the official driver from a trusted source (e.g., WCH.cn or manufacturer's site). Avoid third-party "driver updater" tools.
Extract the ZIP file. Look for CH341SER.EXE (the installer).
Run as Administrator.
Click Install. A system prompt may appear – confirm installation.
Once done, connect the UB93 device. Device Manager should show USB-SERIAL CH340 (COMx) under "Ports (COM & LPT)".

Note: Windows 10 may initially block unsigned drivers. If installation fails, restart Windows in Disable Driver Signature Enforcement mode (Shift + Restart → Troubleshoot → Advanced Options → Startup Settings → Restart → Press 7). For CH340/CH341 (most UB93 devices)

1. Abstract

The "UB93" designation typically refers to a specific chipset found in third-party USB Wireless LAN adapters (Wi-Fi dongles), often utilizing Realtek or MediaTek architecture. Windows 10 generally includes a robust library of generic drivers; however, specific chipsets like the UB93 often require manual driver installation to function correctly. This paper outlines the identification of the device, methods for obtaining the correct driver, installation procedures, and troubleshooting common error codes. Open Device Manager &gt

What "UB93" likely refers to

Device ID / Chip ID: UB93 is probably a vendor/device identifier seen in Device Manager as an unknown USB device (e.g., USB\VID_xxxx&PID_0xUB93 style).
USB to serial / chipset family: Many unknown USB entries correspond to USB-to-serial adapters, network dongles, card readers, or media devices that need drivers.
Third-party product code: It may be an internal model/code used by a manufacturer (often shown when Windows lacks a matching driver).

5. Common Issues & Fixes

| Issue | Solution | |-------|----------| | Code 10 / Code 31 (driver won’t start) | Disable driver signature enforcement (see step 4.2) and reinstall. | | Flickering / no signal | Use a shorter USB 3.0 cable. Avoid USB hubs. | | Only mirror, no extended mode | Press Win + P → Extend. Update GPU drivers. | | BSOD (IRQL / KMODE) | Wrong chipset driver. Revert to Fresco Logic driver. | | Adapter detected as “USB 2.0 Hub” | Faulty USB port or fake chip. Try USB 2.0 mode (works but slow). |

4. Installation Procedure

Direct working version (often used for UB93):

FL2000_Win10_3.5.0.44250.zip
Mirrors: Look on DriverPack or Station-Drivers (verify SHA256 if paranoid).

Installation:

Download the official CH340/CH341 driver from WCH.cn (Windows 10 certified).
Uninstall any existing Prolific drivers first to avoid conflicts.
Run SETUP.EXE as administrator.
Plug in the UB93 device. It should now appear as a COM port.

Check your hardware ID to be sure:

Open Device Manager > Right-click the unknown device > Properties > Details > Hardware Ids.
If you see VID_1A86 or PID_7523, you need the CH340 driver, not Prolific.
