'Error' communicating with KManager

[rmthio]

Hi there, my K Pro had been running fine until a few months ago the CEL started to lights up occasionally. But recently, it has lights up permanently (along with 4k rpm limit).

I tried plugging it onto the KManager and it shows 'Error' instead of 'Online'. I then tried with another K Pro ECU in the workshop and it works fine ('Online')

Any suggestion what might cause this? Would really appreciate any help, thanks.

What is the serial number that is on the K-Pro board inside the ECU? What shows up in the Windows Device manager when you plug in the USB?

Thanks for your reply.

Windows detected that there was a Device connected on the USB, but it shows 'Error' on the KManager.

Serial # is 10215.

I was told that I should try to re-chip the Hondata on a PRB ECU as it is generally more robust, but will this work with K Pro III?

Please tell me exactly what shows up in the Windows Device Manager when you plug in the USB.
