Add USB ports using a Serial adapter? - usb to serial port adapter

Is it possible to have a USB-serial adapters are used, can deliver to a USB port on your computer via a USB serial port? I have heard of adapters that have a serial port via a USB adapter. If yes, please give me the link to the page. In other words, I want to connect a USB device on my computer, but my computer only has 2 serial ports on them, does not support USB. So I want an adapter that is my USB ports through the series. But only found that the adapter plugs into a USB port if you have a serial port. I want exactly the opposite, but I could not find these products on the Internet.
