ESP32-S3-WROOM-1 Disconnects USB when entering boot mode

So I have a circuit built and I hold the button that grounds GPIO0 and hit reset I get the following on the serial monitor:

invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xfffffESP-ROM:esp32s3-20210327
Build:Mar 27 2021
rst:0x1 (POWERON),boot:0x0 (DOWNLOAD(USB/UART

and then the USB disconnects, so I don't have a COM port to upload to. I am really scratching my head on this one. Any help would be greatly appreciated.

Thanks.

If memory serves, go into menuconfig and enable "Channel for console output". Program it using the TX / RX pins, and reboot it.
It should then be able to flash using USB.
