Part 7: Is the E-UB5 Dongle Still Worth Using in 2025?
The E-UB5 is a legacy product. While it works for basic needs (keyboard, mouse, file transfer), it has limitations:
- No Bluetooth 5.0 or 5.3 – so slower speeds and shorter range than modern dongles.
- No LE Audio – so no LC3 codec support.
- Driver headaches – as documented in this article.
If you value plug-and-play convenience, consider upgrading to a TP-Link UB500 (Bluetooth 5.0) or Asus USB-BT500. Both have official drivers and work out of the box on Windows 10/11.
However, if you already own an E-UB5, or you need low-cost Bluetooth for an older machine (e.g., a retro gaming PC or a thin client), the effort to find the e-ub5 bluetooth usb dongle driver is worthwhile. For less than $5, you get functional wireless connectivity.
