Weird, only thing i belive it could be is either your devices or the motherboard.
As for the motherboard you can get a pci usb controller like this one http://www.newegg.com/Product/Product.aspx?Item=N82E16815283028
and hopefully it fixes your issues.
As for the devices, well getting new ones might not be the best option.
Do you have logitech's latest drivers installed? Try other drivers to see if the same thing happens.
