[chirp_users] MacOS USB connection problems with Yosemite (10.10.5) and a Wouxun KG-UVD1P

Hello, Everyone. I am a brand new chirp user. As it is described in the Subject line, I am trying to connect to a Wouxun KG-UVD1P using chirp. When I attempt to download from the radio, I only have access to two Bluetooth ports. I am unable to access either of the two USB ports on this MacBook Pro.  I am using what appears to be the official Wouxun USB cable I ordered for Amazon.  I checked the relevant chirp pages and all I see are solutions for MacOS versions 10.9 and earlier. I am using MacOS 10.10.5  Any ideas about how I can access the USB port or current driver that will enable me to access my radio?  Thanks in advance. Ed Lomax (e_lomax@yahoo.com)
