Release Notes

USB Connections and Compatibility

The KC12 USB Type C connection located on the subwoofer back panel is used to upload firmware updates on your KC12 Loudspeaker and utilizes a USB 2.0 computer connection protocol. However, computers with built-in USB-C ports may default to using a SuperSpeed+ data connection that is not compatible with USB 2.0.

CASE 1 - If your computer has built-in USB Type A ports, we recommend using these to connect your computer to your KC12 Loudspeaker to perform firmware updates using a good quality USB-A to USB-C cable.

CASE 2 - If your computer only has USB Type C ports, you must use a USB Type C to USB Type A adapter to guarantee proper data speed connection. While using the adapter you can then use a standard, good quality USB-A to USB-C cable to connect to the KC12 Loudspeaker to perform firmware updates.
