Had this problem recently myself. 1. have you checked the batteries? Could be as simple as that. 2. Go into your BIOS and enable usb legacy support (or vice versa).
Did you install the Logitech drivers, or did you let XP install the drivers. I let XP install the drivers myself. Look for updated drivers for both your motherboard and the Logitech site. Turns out my problem was a known issue with my Asus motherboard and found a BIOS update that cured my problem. Good luck.
I keep getting this error when I most OBVIOUSLY have a keyboard hooked up. It's a Logitech wireless, but I think the error is actually in the USB ports. I've tried hooking up an older USB keyboard, and it didn't work either. I can't remember exactly, but I think that the light on the wireless receiver lit up, and no longer does.
What could I possibly do? Is the only solution to find a P/S2 keyboard? Even then, what can I do?
My computer wasn't running properly after unzipping a few .rars and trying to install a game. Nothing was responding, so I restarted and now I'm stuck where I am now.
I swear if one more problem pops up on this computer, I'm gonna have to start using a stone tablet.
