Hello, I'm a custom of ESP-PROG. There is a problem occur to me. I can use ESP32-DevKitC board to download program directly through the computer. The connection is ok. But I cannot use the esp-prog to download program to ESP32-DevKitC board when connection also is ok. What's the reason is? How could...

尊敬的专家，您好！
我是ESP-PROG的用户，按照官方文档上的说明，ESP-PROG可以自动烧写程序，但是我通过ESP-PROG与ESP32-DevKitC开发板连接，接线正确，通过ESP-PROG的USB口无法向ESP32-DevKitC进行程序的烧写，但是ESP-PROG的USB串口打印正常，复位按键正常，boot按键也正常，请问这个问题如何解决？
通过ESP32-DevKitC开发板与电脑之间相连可以自动烧写，证明电脑、USB接口、烧写过程均正确。
希望得到您的解答，谢谢。
