Can't connect to TC66C via USB on macOS

[metawops]

On my iMac (Mid 2011, no Bluetooth LE) running macOS 10.13.6 I was able to install all the requirements and launch the program with python3 (3.7.5).

The TC66C is connected via its microUSB port and a microUSB to USB-A cable to the iMac. (So not via USB-C.)

macOS enumerates the device as /dev/cu.usbmodemTC61 and in Safari 13.0.4 this device is correctly listed:

Clicking on Refresh outputs this in the terminal:

However, when I select this device in the GUI (not the Bluetooth one) and try to connect no connection can be established and the status immediately goes to (stays at) "Disconnected"). 😞 Here's the output from the terminal when I click on Connect:

Any ideas? 😳

Hi, this is bug. Bluetooth address is required for USB connection. My mistake. Update to the latest version and try again.
