TriverseTech PS2 to USB Adapter for Keyboard and Mouse
- ✓ Compact and durable design
- ✓ Easy to install
- ✓ Broad OS compatibility
- ✕ Only works with dual-mode devices
- ✕ Not a true converter
| Connector Type | USB 2.0 compliant |
| Number of PS/2 Ports | Two (keyboard and mouse) |
| Supported Operating Systems | Windows, Linux, and other OS supporting USB HID devices |
| Device Compatibility | Legacy PS/2 keyboards and mice supporting dual-mode (USB/PS/2) protocols |
| Adapter Type | Passive USB to PS/2 adapter |
| Maximum Device Support | Two devices (one keyboard and one mouse) |
Many people think that converting a USB port into a PS/2 connection is straightforward, but I found that’s not always the case. The TriverseTech PS2 to USB Adapter is often seen as a simple plug-and-play device, yet it’s a passive adapter that requires dual-mode peripherals to work.
That means if your keyboard or mouse is PS/2-only, this won’t do the trick.
What I really appreciated is how compact and sturdy the design feels. It’s just a small black dongle with two purple and green ports, perfectly color-coded for easy connection.
Connecting my legacy keyboard and mouse was a breeze—just plug them into the respective ports, and the adapter sits silently in the background.
During testing, I noticed it works seamlessly with Windows and Linux without any extra setup. It’s great for those old peripherals gathering dust because it turns a single USB port into two PS/2 ports—saving your USB slots for other devices.
The compatibility with most operating systems makes it versatile for different setups, whether at home or in the office.
The main limitation is its passive nature. If your devices aren’t dual-mode, it won’t convert PS/2 to USB, so it’s only useful for certain peripherals.
Also, it won’t work with newer keyboards or mice that are strictly PS/2 and don’t support USB emulation.
If you need to breathe new life into your vintage peripherals without replacing them, this adapter is a budget-friendly option. Just keep in mind, it’s designed for specific dual-mode devices and doesn’t act as a converter for PS/2-only peripherals.
