I have just got a Logitech Wave keyboard and mouse combo laser. I installed every thing and turned on the computer. The mouse worked and the keyboard would type; so far so good. Down loaded off the C/D that came with it and did as it instructed. Now neither work but my M/S cordless mouse and keyboard still do. Got update from Logetech site and installed, no help. Went to Logitech site again and did every thing I could find to solve this problem, no help.
Used add/remove and got rid of Logitech. Now the keyboard and mouse work with the exceptions of the special buttons; I'm unable to program them because there is no program. I'm using the Logitech keyboard and mouse now. Used the search function and removed every thing Logitec.
