Windows 10/11 will likely not auto-detect the BTDG07A correctly. You can attempt a forced installation:

Warning: Even if this works, the adapter may connect only to basic mouse/keyboard devices and fail on audio or file transfers.

The Epox BTDG07A Bluetooth USB adapter driver is a piece of computing archaeology. While it is possible to get this dongle working, it is not practical for daily use on modern hardware.

For Retro Enthusiasts: The driver you need is the Broadcom Widcomm 5.0.1.4300 (or CSR BlueSoleil 6.4). Search archives with these specific terms, not just "Epox."

For Everyone Else: Retire the Epox BTDG07A with honor. Place it in a drawer or frame it as a tribute to the early wireless era. Then, spend $8 on a new Bluetooth 5.0 adapter and enjoy instant, frustration-free connectivity.


Epox was once a prominent name in the motherboard and peripherals market. The BTDG07A is a Class 2 Bluetooth USB dongle, typically supporting Bluetooth 2.0 (EDR) standards. While it lacks the range and speed of modern Bluetooth 5.0+ adapters, it is perfectly adequate for connecting legacy peripherals like wireless headsets, older smartphones, and input devices.

For many users, digging this adapter out of a drawer is an exercise in nostalgia or a way to repurpose old hardware. The hurdle, however, lies in the software.

Overall Rating: ⭐⭐ (2/5) – Works well only if you find the right driver; otherwise, it’s e-waste.
