I’d like to know, if anybody managed to program the UV-82 using chirp (or the daily build 20140428) on osx 10.9.2. I read that one might or might not have to disable apple’s own driver for FTDI chipset. I’ve been googleing the topic for a few days now and have not found a way to make it work on my mbp. The system report will tell me that a USB-Serial Controller is there:

When I try to "download from radio” I have four choices in a dropdown menu, each of which will give me an error message:

- /dev/cu.Bluetooth-Incoming-Port error: An error has occurred - Radio did not respond

- /dev/cu.Bluetooth-Modem error: An error has occurred - could not open port /dev/cu.Bluetooth-Modem: [Errno 16] Resource busy: '/dev/cu.Bluetooth-Modem'

- /dev/cu.NoZAP-PL2303-000013FA error: Radio did not respond

- /dev/cu.usbserial  error: Radio did not respond

Any ideas? I am using the USB programming cable from Baofeng, that came with the radio. 

btw. under windows7 (installed on the mbp) it works like a charm.

Cheers,

Chris
