You didn't mention what operating system you are using. The FAQ page mentions problems with Chinese fake chips used in cables which do not work without a lot of bother on the users part of uninstalling the Windows automatically instated driver and using an old driver, saying it's best to use a FTDI based cable.

The cables page addresses these problems:
https://chirp.danplanet.com/projects/chirp/wiki/CableGuide

That page recommends some 3rd party sellers of cables:

There are a few reputable manufacturers of 3rd party cables that are known to be high-quality in the community. If you're looking for a cable, check the following:

BlueMax49ers https://bluemax49ers.com/ is a good source of quality cables, and the owner Mark is a regular supporter of CHIRP. Check out his Software Advisor tool https://bluemax49ers.com/software-advisor/ which helps you select software and cables for your radio, operating system, etc.

get it.
With that said, 
I have an older Baofeng UV-3R HT. It's the very small HT. 
#1) What software does it use?
#2) What cable? A "standard" generic speaker/mic to USB cable, or...?
I'd like to thank you Gentlemen/Ladies in advance for your courtesy.
Experienced replies please.
Milt.
