Recent Windows 10 installs don’t PnP with the C270. You get hung again and again, whatever you try. Being PnP there is zero documentation in the box and there is little in the way of support on the Logitech site. My seller – 7dayshop Limited – were sceptical and unhelpful. Most likely your’s will be the same.
