Problem Description
I am unable to connect to the JTAG interface on pins GPIO18/19 of the chip. However, using Windows, I am able to connect to the JTAG interface. I had to change drivers and reinstall in order for it to work on Windows, so I know that my interface at least works.
I am also able to connect through a USB/UART bridge on both macOS and Windows.
So no issues with the UART, only the JTAG
The output below is when I press the "ESP_IDF Build, Flash, and Monitor" button in VSCode.
The error shown below is "Error: libusb_get_string_descriptor_ascii() failed with -1", and then openOCD stops.
