CHIRP

I recently got a new (very new - early adopter) radio - the Wouxun KG-UV8E. I was told it is based on the KG-UV8D and would work with Chirp using the 8D driver. Every attempt either can't read (failure to connect) or gives the error

• I am running OS X 10.11.5.
• I am running Chirp daily-20160604. (GTK 2.24.10 PyGTK 2.22.0 Python 2.7.2) I am using the serial adaptor/cable Chirp labels dev/cu.usbserial-A403RNWA that came with my Baofeng UV-82 (works great on that one, and my older KG-UV3d & UV6X Wouxuns). This is the only cable I can currently get to work with the signed usb serial (pl2303?) driver I finally found for El Capitan. I have been told that the UV8E is essentially a tri-band 8D (adds 220 band). I haven't been able to get to a working Windows machine to try with the factory software - which appears to be the 8D software on Wouxun's site - just to see if the cable works. Part of that problem has also been having the correct driver for Windows 7 or 10. Did try with the supplied Wouxun cabled software on Windows 10 running under Fusion (have been able to do that for the older radios in the past) - but currently I can't talk to any of my radios that way so I suspect it is a driver issue. Haven't tried with the Baofeng cable.

Wasn't sure wether to call this a Bug or New Model as I'd been informed by the seller's help site (I can send name separatley if requested - not sure t's appropriate too list in the forum- reputable site) that Chirp's 8D driver worked with the radio
