Firmware updates are supported for USB 3.0 devices only. The USB 2.0 device firmware has been stable for several years and no updates are expected for the lifecycle of that firmware.
Firmware updates require an internet connection to the host computer performing the update. If one is not available, the device will need to be sent back to Opal Kelly for update. We charge $25 per device for this service.
Firmware updates are currently only supported on Windows.
