Problem Hooking a USB to Serial Adapter to Cyclone V on the go USB

Thanks in Advance. I'm using the Altera Cyclone V Dev. Kit. It has kernel 3.9.0 which seem to support my USB to Serial Adapter. When I plug it in I see the messages in the /var/log/messages: "usb 1-1: new full-speed USB device number 4 using dwc_otg" When I do an "lsusb" I see "Bus 001 Device 4: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port." I expected to see a device in the /dev directory so that I could utilize this USB port but I don't see a /dev/ttyUSBx . How do I use this as a serial port? Do I need to update to a newer kernel version?

UPDATE I'm Going to repost on the Linux page and update what I've done. But don't have time today so I'll have to do it tomorrow. 

I had to update the kernel but I'm still not getting any output. I'm wondering if the device driver has problem.
