USB Keyboard (g15) not working

[KorJax]

Help

My keyboard isn't working, in windows or in BIOS.  The computer simply doesn't recognize it exists anymore.  However, the G-keys and multimedia keys work (as they are handled buy the logitech drivers).

I've searched google for two hours and every single thing involved the guy asking the same exact question with no responses.

Thing's I have tried that HAVE NOT worked:

1.  Went to check to see if USB Legacy Support was enabled in my BIOS.  It already was, decided to disable, restart, enable it to try and get it to work.  It didn't.

2.  Reinstalled Logitech Drivers to newest version.  Didn't work.

3.  Pluged in and unplugged many times in windows, did nothing.

4.  Cold boot, in every fucking way imaginable.  Did everything from not using the G15 for a day, had it unplugged, left the computer in a powerless state all night with the G15 plugged in (and with it not), etc.  None of these worked.

I'm sure I tried other things too.  Nothing I do fixes this issue for me... and I use the macros and media/LCD controls everyday

Right now I'm using some dirty old crappy PS/2 keyboard.

The only thing I haven't tried is flashing my BIOS.  Problem with that is, it's complicated and involves doing stuff like copying/backing up data to a floppy disk according to the ASUS website (the maker of my motherboard)... which doesn't work when you don't have a floppy drive.  Never mind the fact that it can permanatly damage my computer and isn't even guaranteed to fix my problem.

Any halp?

Have you tried uninstalling the Logitech drivers?  I know that might kill some stuff you use it for, but at least maybe it'll get it working again to start.  I seem to recall that being a solution for fixing their mice sometimes anyways.

Have you tired:

A different USB port?
The G15 in another computer?

Check your device manager in windows, see if it shows the keyboard. I'm willing to bet that your keyboard has gone to a better place.

Haven't tried it in another computer, other USB ports did not work.

Device managers stuff like virtual keyboard profiler and all sorts of other random shit realating to HID devices (copied multiple times) so I can't make any sense of it.

Well, REINSTALLING updated logitech drivers did absolutely nothing. I guess there's no harm in trying uninstalling and seeing if the keyboard works though.

So, literally BRB, Uninstalling.

Damnit, so it was working this morning all of a sudden when I started it up from a coldboot... but then I BSOD'd on startup and had to do a system restore to the day before.  Now it doesn't work again  >

What did you do last night to get it working?

[KorJax]

Shut down my computer, went to bed

So I woke up this morning and it's working.

So how long until it breaks again?

Probibly after I decide to clean out my PC today because I'm getting 90c temps on my cpu under load in this hot humid summer weather

UPDATE:  Cleaned computer, and as I suspected it doesn't fucking work again.  Joy.
