Hi everyone, I recently puchase a USB mouse and when I connected it to the USB device at the back of my computer the system did not detect the mouse. I realise that the usb device controller is not in my device manager. I have gone into BIOS and enabled USB Mouse but still no avail. I have tried the same mouse on my daughters computer and It works. How do I get the USB Controller to function and appear in my device manager. I have 2 USB ports intergrated in my motherboard and also a PCI card with usb ports but nothing indicated on the BIOS the existance of a usb port.
