Check whether modules (drivers) are loaded with the command lsmod

Is your computer recognizing the cable? Check by removing the cable from your computer, put it back and take a look at  dmesg | tail -20  - hopefully you'll see something like:

 4343.736241] usb 5-2: Product: USB-Serial Controller

BTW, I had problems getting Linux Mint running CHIRP to recognize my Wouxon KG-6UV but it was automatically recognized by my Arch Linux laptop, I gave up and just use CHIRP on my laptop.
