No matter what you are intending to do with OsmoseUpdater, please pay attention to these precautions:

🆕 Always use OsmoseUpdater's latest version. The application is downward compatible with older Osmose firmware versions. Minimum requirements for OsmoseUpdater are macOS 10.12 or Windows 10. Do not try the update from an older, incompatible machine.  

🔒 Lock Osmose’s power supply to prevent accidental disconnection. When inserting, align the power connector’s wings to match the horizontal notches on the power input. Push firmly, then rotate the barrel clockwise to secure it to the casing.

🔗 Use the original Expressive E-branded USB cable. If not at hand, use a high-quality cable no longer than 2 meters.

🤝 Connect Osmose to a dedicated USB port. Avoid using USB hubs if you can. 

⛓️‍💥 Disconnect all other USB devices from your computer as far as possible during the update.

🔋 Deactivate any power-saving options that may make your computer disable its USB ports or switch off entirely after some idle time.

🔌 Plug your computer’s power supply when performing the update from a mobile device.

☝️ Make sure that no other application is running that could occupy the USB MIDI port of Osmose (no DAW, no Haken Editor etc.).

If you have problems establishing a stable USB connection with your system, it's worth trying to launch the update from a different compatible computer.
