HifimeDIY USB Isolator Full Speed Only, Does Not Support USB High-Speed

The HifimeDIY USB Isolator is designed to eliminate ground loop noise and interference in audio equipment connected via USB. Customers have successfully used it to resolve noise issues with various devices such as MIDI controllers, microphones, DACs, and audio interfaces. However, it's important to note that the isolator only supports full-speed USB and may not be compatible with certain high-speed USB devices like the Focusrite Scarlett 2i2. Some customers have reported positive results, indicating that the isolator effectively removed unwanted noise from their setup. However, a few users experienced issues with the product not working as intended. One customer mentioned that the device shut off their DAC due to default Windows power settings, although they were able to resolve this after making adjustments. The return policy was criticized by one customer who found it inconvenient to return the product due to its ineffectiveness and the associated return shipping costs. In summary, the HifimeDIY USB Isolator has shown to be effective in eliminating ground loop noise for many users, particularly with low and full-speed USB devices. However, some customers have encountered compatibility issues or found the product to be ineffective in their specific setups. **
