There is an issue on both SuperLab 6 and X6 in Sierra 10.12.6.
They cannot recognize the RB830 responsepad.
I also installed again newest driver from the support link but there was no change.
I tested SuperLab 5 and it recognized RB-830 properly.
So, I suspect some incompatibility in compiled dylib in 6 and X6.
Please check it.
