SimRacingBay simucube 1 OSW keeps disconnecting randomly

Hello everyone, I finally managed to make work my SimRacingBay simucube 1 OSW and it keep disconnecting while playing, I tried different USB cables, I have a ground cable plugged into the base.

Anyone as faced the same probleme by the chance ?

Are you plugged into USB 2.0 Ports?

I would connect to the USB ports directly on the PC motherboard.

i tried on my other computer same problem , i would like to know if its coming form the mother card or the ioni card in the Power unit box , even when the wheel is not plugged on my computer the wheel base restart and re calibrate by itself.

Granite software ask me to do an update of the firmware ioni several time even if i do the update it keep asking like if there is a bug or somthing …

im thinking about replace the mother board or the ioni card of the wheel but im not sure wich one causing the problem

Does the torque level have anything to do with it? I mean, could it be the power supply tripping out?

how to know that ?
the leds of the ioni card flash red before the base restarts.

Well, if you reduce the torque levels (drive with less FFB) then does it still happen?

this happens even when the base is not plugged into usb.
with the basic settings on simucube too.

This also happens even when I’m not in game.

Communication error flags:

  • Communication (cheksum mismatch)
  • DataLegth (timeout or app error)

Disconnected. See troubleshooting at while accessing parameter: name=undefined, addr=202, GUI value=-1, HW value=-1

here is a message that is displayed when the base disconnects on granite

so how to change the ffb on granite?

what else can it come from? I’ve been looking for 2 months without finding anything. I despair

There is a slider in Simucube Configuration Tool. Or are you running MMOS firmware?

I use simucube configuration tool and even with the ffb at 5% it does the same to me

I was told that the problem may come from the power supply in the box
