Hi Nic - on any Linux system - and the Mac is Linux based - try
typing in a terminal window.<br>
<br>
dmesg<br>
<br>
This might require root privilege<br>
<br>
At the end of the of output in the terminal window will be the
device and system port being used. <br>
<br>
For example, in the case where you unplug the device and plug it
back in, on my system it prints out <br>
<br>
[755460.454330] ftdi_sio 1-1.3:1.0: FTDI USB Serial Device converter
detected<br>
[755460.455664] usb 1-1.3: Detected FT232RL<br>
[755460.459439] usb 1-1.3: Number of endpoints 2<br>

What data lead were you using? If it uses a Prolific
USB-Serial <br>
bridge, it may be an old type of chip, or a clone. Either way
Windows <br>
(and many Mac systems) will not use them. (Without
compromising the <br>
security of your system by blocking automatic updates and then
manually <br>
installing an earlier driver suite.)<br>
<br>
But Linux (even recent distro's) use them just fine,
regardless. Had <br>
similar issues locally, with a group that uses dozens of
Baofeng <br>
radios. All the interface leads used "hookey" chipsets. A
Windows box <br>
and a Mac, both failed. My old Dell running Mint, "just
worked"...<br>
<br>
Counterfeit IC's are rife in that part of the gadget after
market.<br>
<br>
Take care.<br>
