Sorry, nothing new from my side. All current updates are installed but still EP0000323846 fails to install. I tried to explore the system with Aida64 which shows that on Port1 Hub3 might be present some HID compliant vendor-defined device with HID\VID_1B96&PID_0F03&REV_0001&Col01.
But no idea if it is anyhow connected with this keyboard and missing keyboard receiver. Neither how to use this info. Sony/VAIO seems to stay aside of customers needs and does not suggest any solution. Pity. The only thing which may help to "cool-down" is that the dead keyboard is ****** even when functioning - non-ergonomic, slow, with frequently missing keys input when typing a just a bit faster... But still, it's better to have it than not...
