The Acer care centre failed to update this driver. I have found more than 6 drivers for Win 8.1 on the Intel support page, but have no idea which to use. Very technical language.
Any help gratefully accepted.
Hello @TGall3 ,
Many thanks Leon for your assistance. I confess to being technically illiterate. This problem with the serial IO driver I suspect is stopping me connecting other peripherals to my laptop. Acer support is non existant. I came here as it is an Intel driver.
Once again, thank you , have a great day.
