You have missed some information needed to be able to help:
Type of camera?
Exact version of Lightroom?
Do you see the camera in the Explorer or in Devices in Windows once connected?
What happened when you insert the memory card in an card reader and connect it to the PC/Mac?
Do you see images? Can you import them in Lightroom?
It is a Canon EOS 80. I use Lightcoom CC2015. Lightroom recognizes the camera but says there are no images. Yes i see the camera when I open windows explorer thats how I am able to import it to my hard drive.
Sorry do not have a card reader.
Please post the exact version of LR (2015.x) and a screen-capture of the import window
Use a card reader.
You need Lightroom CC2015.5 or newer to work with the EOS 80D. The best is that you update to the latest version of LR and try it again.
Thank you will try that
