How can I fix my mikomi AP-7121 webcam ?

Hi there, I have just purchased the Mikomi AP -7121 webcam and thought I had installed it successfully. I plugged in the webcam and it came up that no usb device was recognized. I tried my other usb port and nothing happened. I looked it up and it said I had no drivers installed, but I have the cd and was sure I had done it correctly. Can anyone help?
