I have just put together a new pc for a mate of mine, i set everything up with ps2 keyboard and ps2 mouse which work ok.He has a logitech cordless keyboard and mouse ( which works on his old pc) but when i plug in the usb receiver, a message pops up " usb device not recognised" device manager shows no yellow exclamation marks, but under "Universal serial bus controllers" it has unknown device " no drivers are installed for this device". I have tried uninstalling the device, and searching for a newer driver but still no joy. Any help greatly appreciated.
Still struggling with this one, iv'e enabled legacy usb in the bios but it's made no difference. Not sure how to set up the channels as it came with no manual, i have just plugged it into my computer and it set up instantly and works fine.
