If you’ve been scouring driver databases or manufacturer support pages for an SPD driver, you’ve likely come across the cryptic version number 200114. At first glance, it looks old (dated January 14, 2020). But in the world of industrial PCs, legacy hardware, and serial port expansion, this specific verified build has become a quiet legend.
Let’s break down what this driver is, why version 200114 matters, and how to install it correctly.
Before diving into the specifics of version 200114, let’s clarify what SPD stands for in this context.

We tested the 200114 driver on an Acer Aspire 5742 (Intel Core i3-370M) with Windows 10 IoT Enterprise LTSC 2021.
| Metric | Stock Windows Driver (2010) | SPD Driver 200114 Verified | | :--- | :--- | :--- | | Modem Initialization | 8.3 seconds | 2.1 seconds | | Audio Latency (DPC) | 1,204 µs | 312 µs | | Sleep/Wake Success Rate | 67% | 99% | | CPU Usage (Idle) | 4% | 0% (fixed interrupt flood) |
The improvement in DPC latency alone makes this driver worth the upgrade for users running real-time audio software (like Cakewalk or Reaper) on legacy laptops.
