Yes, mine came with a cable. It's a USB-A to 8 pin that plugs into the mic jack.
The software provided by Radioddity is one step above worthess, however. You cannot Alpha tag memories, nor adjust any radio menu settings. If you enter Alpha tags using the radio keypad then write some new memories using the so-called "software", it will wipe out your alpha tags. Ask me how I know .
I spoke to RT Systems at the Dayton (Xenia) hamfest and they said they might have a version of their software out for it in the future, but it's a back burner issue. They indicated that the programming for this radio is a "convoluted mess." Their words, not mine.
Chirp saId that they will work on a version once they get a test radio and if "a programmer has the time/interest to do it". Again, their words.
Have fun.
