I'm new to this forum thing, so please forgive me if I'm in the wrong place!
I have an Acer TravelMate 4050LCi Laptop, just over a year old, running XP home. Although, when I plug my optical mouse into the USB ports its light comes on, it won't work. Nothing will work, printer, phone, camera etc. I've been searching through the web for fixes and have tried all the ones I can find, including uninstalling and reinstalling, updating drivers, editing the registry, working through some DOS commands, but still nothing. In Device Manager all seems OK, no errors. I'm now tearing my hair out! Any ideas, please!
