TL:DR: Get a new G815 as the one you currently have is faulty and Logitech wont take responsibility admitting the product is faulty. If you are here in search for a solution you came to the right place.įirst of make sure you've already tried all the possible solutions provided by Logitech and their tech staff, if ultimately your G815 is not detected by GHUB then I got a fix for you as your current G815 is definitely faulty and will NEVER be detected by GHUB.
