I am new to Hand Held HAM radio and have a ton of trouble getting the radio to connect with the computer. Radio is BF-F8HP
Operating system is Mac 10.8.5
I have installed everything Instructed to from the Chirp site.
including the osx-pl2303 installer and the python runtime files

I start Chirp
plug in the cable, and then the radio, and finally turn on the radio
I then select Radio > Download from radio
select Port (and there are several to select from:


1. /dev/cu.Bluetooth-modem
2. /dev/cu.Bluetooth-Serial-1
3. /dev/cu.Bluetooth-Serial-2
4. /dev/cu.Bluetooth-(myname)-Wireless-iAP
5. /dev/cu.Bluetooth-PDA-Sync


All of which result in
1. Chirp starts processing a gives error 16 Resource busy could not open port /dev/cu.Bluetooth-Modem
2. for serial-1 it appears to start cloning and then reports: radio did not respond
3. for serial-2 it appears to start cloning and then reports: radio did not respond
4. for Bluetooth (myname) Wireless-iAP it appears to start cloning and then reports: radio did not respond
5. could not open port /dev/cu.Bluetooth-PDA-Sync: [Errno 16] Resource busy: '/dev/cu.Bluetooth-PDA-Sync'

Could anyone help me here,
thanks,
Tom
