Ub93 Driver Windows 10

Investigating “UB93” USB-to-Serial / USB audio driver on Windows 10

• Many USB adapters and dongles use chipsets from vendors (Prolific, FTDI, Silicon Labs, CH340, etc.) and sometimes report opaque IDs or model strings like “UB93.” That label alone isn’t a standard vendor model; it’s typically a firmware string or product name embedded by the manufacturer. Proper driver selection depends on the device’s USB vendor ID (VID) and product ID (PID), not the displayed label.

• Restart PC → Press F8 / Shift+Restart → Troubleshoot → Advanced Options → Startup Settings → Restart → Press 7 (Disable driver signature enforcement).
