USB Camera 设备描述符解析错误 (AEGHB-898) #439
Comments
应该是你这个摄像头不支持在 USB 1.1 Full Speed 下工作,可以用接上 USB 隔离器后再抓一下描述符。 It seems that your camera does not support working in USB 1.1 Full Speed mode. You can try connecting it through a USB isolator and then capture the descriptors again. |
尝试了一下接了一个usbhub后无法识别到设备了 |
硬件限定的,除非你换 ESP32-P4 |

使用ESP32S3 OTG USB开发板进行开发,使用官方示例项目usb_camera_mic_spk进行摄像头推流时。接入摄像头后发现usb设备描述符解析与windows的 usbtreeview.exe解析结果不一致,导致识别不到usbCamera的Video Streaming MJPEG Format Type Descriptor,无法进行摄像头推流。不一致数据如下图所示
