Hello Wait 


In the past a lot of people trying to program the the Baofeng for get to put the radio in VFO mode and turn the volume along way up
I use a Mac and did not install a driver and the Mac found the USB port I have plugged in 

USB-Serial Controller:

  Product ID: 0x2303
  Vendor ID: 0x067b  (Prolific Technology, Inc.)
  Version: 3.00
  Speed: Up to 12 Mb/sec
  Manufacturer: Prolific Technology Inc.
  Location ID: 0x14700000 / 9
  Current Available (mA): 500
  Current Required (mA): 100
  Extra Operating Current (mA): 0




I did get the use not showing on my Mac once  so I rebooted the system and it came up

Hope this helps
