This rig came with a Logitech gaming mouse and keyboard as part of a gaming bundle- some time ago now, but the teething problems associated with their driver have all but turned into deep sockets!
Firstly, a major inconvenience is that any native system hibernate key function is unavailable on the keyboard running only on keyboard.sys until a hibernate function macro is manually added through the Logitech driver UI interface. Which also means you have to launch the driver manually- manually because for some daft reason it never has and never will run properly when configured to run after Userinit.
Now having the driver in the background is a risky business because it does a lot of weird and not so wonderful things- like checking your files. For example, this was logged from Process Monitor:
LCore.exe 5396 QueryNameInformationFile C:..myexefile.. BUFFER OVERFLOW
Yea, just copying any old file in explorer- so what's LCore doing with it- and why the Buffer overflow?
Also, pressing the G2 function key always produces an endless series of these characters until G2 is pressed again:
wdwwdw w wwwwwwwwwwwddwdwf wddwwwwwwddwdd wwddd wddwwwwwdddddwwwwwwwwdwdwwwddddddw wddwwwwwww w wwwwddddwwww wwww wwdw wwwweeww wwwwwwwwwww wwwwwwwwwwwww wwwwwwwwwww zzz wwwww ff zz zz wwwwwwwww z zz s f t w zzz www wwwwww w qqqqqw w z zz t w f ww wwwwf wwwwww w www wwwwf wf f f f wwwwwwwwwwwwwqwwwwddddwdddddwsf s zzz s w wwwww w wdwwdw w wwwwwwwwwwwddwdwf wddwwwwwwddwdd wwddd wddwwwwwdddddwwwwwwwwdwdwwwddddddw wwddwwwwwww w wwwwddddwwww wwww wwdw wwwweeww wwwwwwwwwww wwwwwwwwwwwww wwwwwwwwwww zzz wwwww ff zz zz wwwwwwwww z zz s f t w zzz www wwwwww w qqqqqw w z zz t w f ww wwwwf wwwwww w www wwwwf wf f f f wwwwwwwwwwwwwqwwwwddddwdddddwsf s zzz s w wwwww w
As some of these issues were reported before the site was revamped to eharmony, one would hope the old posts are still accessible. But nothing- neither at the site- or the community, so that's efficent customer service.
And could the driver also be causing odd things like the unavailable process handle and the shell interface blown out of the water (See the second post to this)?
