OK i have had Win X64 installed on my box now for about a month and a half. Works ok had some issues (to be expected) but now my keyboard WILL NOT WORK. I have a USB Logitech elite KB. I have tried using the USB to PS2, every usb port, and even trying to plug the PS2 in to the mouse port just to see if it would work. Nothing. I am like 99.999% sure it is the driver from what i see in the device manager but no mater what i select for the KB i get an error 41 or 19. I have tried to search for it and the only thing on Logitech's website for this is for some mouse's and i can't use the 32bit prog because my os kicks it back. I am looking for the actual inf files and what not to install this if any one could PLEASE help me. If i can't get it to work i'm gonna have to format and try again and i have over 300g of data i would have to back up to DVD's (not fun). Please help.
