I’m fighting with a very strange problem which appears in Assetto Corsa, Assetto Corsa Comp and RFactor 2 for about have a year now. I start the game and begin to drive. I’m using also VR. Suddenly, but mostly after a strong impact (colision or jumping over a high curb) my wheel turns by itself to one side (right or left to the bumpstop and stays there). If you wanna turn it back it goes by itself again back to the bumpstop. The games crash (freezes) and also the Simucube Software freezes. So the only solution is to turn off the Simucube hardware and turn it on again. As soon as the Simucube is off Windows also reacts again on mouseclicks. So i can close Simucube software and restart it again.
Strangely this problem never appeard when i played Forza 7 or Forza Horizon 4 with the Forza Emu Wheel Software and i played it a lot.
I also have a motion system (SFX100) running (for AC, ACC, RF2, Forza 7 and FH4), but i have no idea if it influences the Simucube in some way. The problem didn’t show up if the motion system was off, but that could be also maybe just coincidence. My motion system is also running with the Forza games and there i have no problems at all.
Any idea what i could try or if i can record some protocol?
For example, if a USB button box is disconnected when iRacing is running, the Simucube will go full torque against bumpstop. I’ve personally seen it happen.
It is a windows issue - game controller order gets messed up when device disconnects and iRacing does not communicate with the correct controller anymore.
edit: And it doesn’t need to be much more than a momentary hickup. You can also test if this happen - set “low” torque level in Simucube so as to not damage anything, and then disconnect the button box while driving.
it happened to me days ago with ACC on Sport, wheel’s usb got disconnected and it started turn against bumpstop…I also heard the start-up sound of the motor, so I went to look True Drive and it was like it had just started with ready safe profile loaded…I was really worried something was very wrong, but since then it’s all normal, I had no issues at all…
I’m running my rig with a motion system (SFX 100) and the problem just appears if i connect the power of the motion system in the same room as i power my simucube. So maybe EMV problems, but i can live with that solution.
You should put a line-filter on the SFX-100 AC 220V input side. Most don’t do it, I suspect the resulting conductive noise back the AC feed is quite bad, causing all weird problems on other equipment connected to that same feed.
And of course you have shielded power-cables to your servos, with shielding connected to Protected Earth on Controller side? Included on Simucube?
All these small things add up to cause big problems if not taken into account during the build-phase. Saw this very often when people were building OSW’s…
This time it happened while driving, yes. That is why I think it had such effect on the wheel.
I had heard this usb unplug sound before, but I’m not sure how to find the source of the problem. Any suggestions?
I think I found the problem. I looked into windows devices, and I could see one “malfunctioning USB device”. There was no information to what the device was. I disconnected all usb devices one by one and found out it was my shifter.
I changed the usb port where I connected the shifter to a USB hub instead of directly on the motherboard and the problem disappeared.
I don’t know if this solves the original problem, but I’ll give it a go now and report if it happens again.
This happened to me during an endurance race tonight. Wheel went fully to left and locked. It became none responsive in game. I’ll be checking on my usb devices. It’s dangerous that the wheel can suddenly go full speed to bump stop because an alternate usb device possibly malfunctions/disconnects.
Is there any new/updated information for this simucube2 behaviour? I want to just make sure I troubleshoot this efficiently. Thanks
