Windows 10 OS with latest updates (64 bit)
Logitech Webcam C270.
Have installed latest drivers from Logitech site.
Always get a "Webcam not connected error"
and if unplug and then plug in again windows reports "Unrecognized USB device"
Logitech do NOT respond to email request for help.
Have tried all ideas found on the Internet to no avail.
Many thanks for any assistance.
I'm not sure that I have a solution, but you can try uninstalling the drivers and trying other Logitech drivers that are close to the c270... I had a generic webcam once where I lost the CD that had its drivers. I ended up searching on Google and finding generic drivers that made it work.
