We were having problems where the wheel would randomly disconnect mid game when it wasn’t under load (i.e. usually driving in a straight line). It was infrequent. Saw there was an update to 50.4b (was running 50.4). Downloaded firmware, chose to update when prompted and it got stuck so clicked cancel.
Now the problem continues. The bug in the software means that we don’t see the “cancel”/“update” when message prompts that it found device in firmware update mode.
So thoughts for the next step were to flash ion directly (based on this video for guidance: https://www.youtube.com/watch?v=UY903mu91qA) but now have no way to put into the correct mode using Simucube tools and it doesn’t come up in device manager even after installing the recommended EXE drivers, no luck.
If the upgrade fails, there could be some issue in your PC’s USB connection. Try with other USB ports or another PC, also with another USB cable. If the problem persists, then I would suspect a physical failure of the USB port on the Simucube.
