## Problem Description
我最近在使用esp32c3的USB-JTAG调试系统,却发现esp32c3的usb-cdc串口可以正常工作，但却无法正常调试。经我排查发现，发现系统可能就只加载了usb串口设备，没有加载USB-JTAG设备。
## Debug Logs
使用openocd 调试esp32c3 使用 USB-JATG，发生以下错误，没有找到JATG设备
```cjia@cjia-com:~$ openocd -f board/esp32c3-builtin.cfg
Open On-Chip Debugger v0.11.0-esp32-20211220 (2021-12-20-15:42)

这是 lsusb ，发现可以找到Espressif USB JTAG/serial debug unit

我发现似乎只加载了USB ACM device
