I tried version 3 up to version 4.19. No version of hcitool will pair with the mouse. A "hcitool cc "bt address of mouse"" will give a Input/Output error. Hidd -s , however, will pair with it. Appears hidd has been removed from version 4 though. -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
