The primary issue with the ES-388 adapter lies in its chipset. Most ES-388 dongles utilize a Cambridge Silicon Radio (CSR) chip, specifically the CSR8510 A10. While Windows 10 includes a generic inbox driver for many Bluetooth radios, it often fails to recognize the ES-388 correctly. Instead of installing a functional driver, Windows may label the device as an "Unknown USB Device" or a "Generic Bluetooth Radio" with limited functionality. This occurs because the ES-388 is frequently produced by multiple, unbranded manufacturers who sometimes alter the device’s hardware ID or fail to pay for Microsoft’s certification. Consequently, Windows 10’s automatic update mechanism cannot fetch the correct driver, leaving the user with a non-functional dongle.
