最近我遇到了这个问题,很头疼,我已经在这个问题上花了一个星期了,但仍然失败。希望您能帮我把这块石头踢开,非常感谢。
我的问题:
我们公司为iPhone生产USB存储设备,实际上这个存储设备中有一个SDCard。现在,我们想要开发一个 Mac 应用程序来更新该存储设备的固件。但是每次我将存储设备连接到Mac时,Mac都会自动安装它,并且总是失败kIO返回独占访问当调用USB接口开放.
我也尝试写一个无代码驱动增加探测分数,但仍然不起作用。我不知道我是否走错了路,或者编写无代码kext时犯了一些错误,例如,写了一些错误的IOClass,错误的bundle ID。
我的无代码 kext info.plist 是:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

以下是我的存储设备的 ioreg 结果:
