[chirp_users] Programming Baofeng UV-9

I'm helping a group program their new radios. They have Baofeng UV-9, not 9R, but UV-9. There are no manufacture labels except in the battery compartment. It appears to be a UV-5R variant as it incorporates the Kenwood standard 2-pin plug and a 5R spkr-mic works with the radio. I'm using the same cable that I use with my 5R but the radio fails to respond to Chirp no matter what radio model I use in the Baofeng and BTECH listings. Is there a preferred for this radio. By the way, it doesn't show a firmware version on power-up.
