This update method is required to use the latest launcher versions. You have two options: Use the 1.2 firmware version available here: FSBLauncher v1.2.0 Send your unit for a one-time firmware update, which costs $50 per unit plus shipping. After this update, you'll be able to update the firmware via USB. Note: If you are using older v1.2.0 and it feels like the knobs rotation skipping, it means the encoder speed is set too high for the newer version of the launcher. To make it work well with 1.2.0 version, you need to slow down the encoder speed to "5" using the Encoder Speed Mode below. Encoder Speed Mode. This will enable to increase / decrease encoder speed mode on a scale from 1 to 10 (by default it's 5). However currently, if you increase beyond 5, X-Plane / MSFS will not be able to read it. Press and Hold "HDG" knob. The buttons will illuminate showing the current speed. Use "HDG" rotation to adjust encoder speed. Press "HDG" again to exit the encode speed mode.
