I'm not having any problems with my Logitech G110 keyboard or my G13 gameboard at present but I've been thinking of upgrading to a G510 so I'll have another LCD to monitor hardware usage and temps while I'm playing (without having to switch back and forth or having extra gadgets on my monitor screen.) So I've been doing my research on the net.
I've run across a lot of people reporting that their gaming devices are causing various lags, freezes, crashes, hangs and BSODs in a number of different games. The consensus seems to be that the game devices' drivers are sometimes conflicting with the games' code on some rigs or problems with some mobo USB implementations and physical connections. It also appears that some games are causing game device driver corruption because many people have been reporting success after wiping the old gaming device drivers and either installing new updates or simply reinstalling their present ones (much the same as with video drivers.)
So, if you're experiencing any of the above problems and using gaming device drivers add yet another possible fix by fresh downloads and installation of the drivers from your manufacturers' web pages.
As with so many problems there are too many variations in PCs out there to narrow it down to a common cause but it won't hurt to add this one to the list too.
