There are several limitations to the USB console feature. These may or may not be significant, depending on the type of application being developed, and the development workflow.
1. If the application accidentally reconfigures the USB peripheral pins, or disables the USB Serial/JTAG Controller, the device will disappear from the system. After fixing the issue in the application, you will need to manually put the {IDF_TARGET_NAME} into download mode by pulling low GPIO0 and resetting the chip.
