Thunderbolt Firmware updater for Windows. This release updates your Sonnet Thunderbolt 5 product’s firmware to version 64.1.69 to improve general reliability. This updater runs only under Windows; Mac users must use the macOS version of the updater.

Notes
• Before running the updater, you must disconnect all devices from your Windows host except for the Thunderbolt 5 device you’re updating.
• If you’re updating Dock, you must also disconnect all downstream devices connected to the dock; the firmware updater cannot launch unless all devices are disconnected from the dock.
• Before running the updater, “safely remove” (eject) any installed SSD.

The problems can be very different (some ports fail, multiple cards in the same chassis have issue, video distortion, video/audio lag, etc.)

Update the firmware on the BMD card to the current version, and the issue in the Echo will be resolved on both Windows and macOS.
