除了文件传输之外，我无法连接我的 Sony A7RII 相机；lsusb没有显示与相机相关的输出。
最新版本gphoto2已安装并gphoto2 --list-cameras| grep -i "A7R II"声称支持相机（libgphoto2 网页大胆地声明了“图像捕获、触发捕获、实时查看、配置”功能）。
这远程文档警告使用 libgphoto2 2.5.13 或更新版本（我已经检查过了）。
env LANG=C gphoto2 --debug --debug-logfile=my-logfile.txt --config以下是is的输出

最后，这是由布线引起的：我使用的 USB 线缆是仅用于充电的线缆。
您必须确保电缆连接所有四个引脚
