I have 6 USB ports I use a mouse and plug it in the back and it doesn't work. If I plug it in the front it works but here is another problem the USB only transfers at a minimum rate at 550 kb/s! It used to transfer at 20 mb/s. How do I fix this?
First of all, you need to post your exact system specs ie make and model of mb, brand and wattage of pw supply, amount of ram, etc. It is difficult at best to help you without the system sitting in front of me; without knowing what I am working on, it becomes impossible. If this is a big box system ie dell, hp, whatever, post the exact make and model number.
Next did you do anything ie clean install of windows, install any new software, install any new hardware, etc?
