Similar issue, h115i on Intel motherboard. Product name : ROG MAXIMUS XI HERO (WI-FI) - latest bios Manufacturer : ASUSTeK COMPUTER INC. ----------------------------------------------------- CPU ----------------------------------------------------- Name : Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz ----------------------------------------------------- 32GB Ram Windows 10 ver 19043.1165 H115i platinum, v 1.01.15, commander pro, HX750i. Several QL and LL fans iCue v4.13.223 . I see there's an update to 4.14.179, so I'll try that in the mean time. I see a lot of references to this issue on Reddit, along with 'hey, follow this thread it fixed it ' leading to the corsair forums, but the thread no longer exists when I follow the link. This is happening alot - like multiple times time an hour. Visor is running linked across all Corsair components --------Log Snippet----- 2021-08-29 10:23:53.9264 | 55 | INFO | H115i Platinum | Reboot EFM8: Step #3-1: Verify device status... 2021-08-29 10:23:53.9390 | 55 | INFO | H115i Platinum | Reboot EFM8: Step #3-1: Verifying of status got an exception: CorsairLink4.Module.PlatinumDevices.Common.Exceptions.PlatinumDeviceChecksumException: The response to the command 0x00 contains wrong CRC8 checksum 0x00 <> 0xF1. at CorsairLink4.Module.PlatinumDevices.Common.Packets.IncomingPacketBase.Verify() at CorsairLink4.Module.PlatinumDevices.Common.Packets.IncomingStatePacket.ToSettings() at CorsairLink4.Module.PlatinumDevices.Common.PlatinumDeviceHidCommunicationHandler.VerifyRebootStep(PlatinumDeviceSequenceCounter sequenceCounter, Int32 step, Int32 iteration) 2021-08-29 10:23:53.9390 | 55 | INFO | H115i Platinum | Reboot EFM8: Step #3-1: Step failed 2021-08-29 10:23:53.9390 | 55 | INFO | H115i Platinum | Reboot EFM8: Step #4-1: Reboot EFM8 and XMC 2021-08-29 10:23:53.9390 | 55 | INFO | H115i Platinum | Reboot EFM8: Step #4-1: Sending the reboot packet... 2021-08-29 10:23:53.9390 | 55 | INFO | H115i Platinum | Reboot EFM8: Step #4-1: Got an exception: System.IO.IOException: Operation failed after some time. ---> System.ComponentModel.Win32Exception: A device attached to the system is not functioning --- End of inner exception stack trace --- at HidSharp.Platform.Windows.NativeMethods.OverlappedOperation(IntPtr ioHandle, IntPtr eventHandle, Int32 eventTimeout, IntPtr closeEventHandle, Boolean overlapResult, NativeOverlapped* overlapped, UInt32& bytesTransferred) at HidSharp.Platform.Windows.WinHidStream.Write(Byte[] buffer, Int32 offset, Int32 count) at HidSharp.HidStream.Write(Byte[] buffer) at CorsairLink4.Module.PlatinumDevices.Common.PlatinumDeviceHidCommunicationHandler.PerformRebootStep4(HidStream stream, PlatinumDeviceSequenceCounter sequenceCounter, Int32 step, Int32 iteration) 2021-08-29 10:23:53.9390 | 55 | INFO | H115i Platinum | Reboot EFM8: Step #4-1: Rebooting EFM8...
