Yes, please post where to find this error.
Got 2 Surface Pro's here, one of mine, and one of my dad's. This last one got disconnected with the type cover a couple of weeks ago, aren't able to fix this. Switched both type covers, but on mine both type covers are working perfectly, and both type covers aren't working on the SP4 of my dad :-(
Kind of done with this issue now
Im sorry, cant say where, its a log file not a configuration file. Find words with error in it og for easyer ready try the program cmtrace or some other log tracer program. You can also try to uninstall the driver and then look at the log when you install it again to see what it say.
Cants say where mine was, dont have that surface anymore since it was replaced. Hope it helps a bit.
