Sorry about the delay getting back to you. Unfortunately your workaround didn't work. However, this morning I set-up another user on the laptop and when I plugged the projector's USB cable in, everything was recognized just fine and the remote worked perfectly for that user. So, I will check other users and perhaps I will just have to copy the one user profile to the other users.
I have a compaq presario -- and was just given a DELL 2300 MP as a gift. It doesn't seem compatible. It keeps searching for a signal. Do I need a driver... or is this not going to work with my unit.
