Macos 用于usb存储设备的无代码kext
在一个项目中,我最近试图通过osx 10.9.5上的libusb访问usb存储设备。但很明显,一些默认的驱动程序声称该设备,我无法访问它。当我尝试通过libusb访问它时,它返回“权限不足” 当我在Ubuntu中执行(java)应用程序时,一切都正常工作 我在互联网上的研究表明,提供一个无代码的kext,在更高的probescore上匹配该设备,可以防止默认驱动程序声明该设备。这将完全解决这个问题,因为卸载IOUSBMassStorage kext使我们能够使用该设备执行所需的操作 我尝试创建一个无代码的kext并没有像我希望的那样成功,因为它似乎既不会在启动时加载,也不会在我使用Macos 用于usb存储设备的无代码kext,macos,storage,libusb,iokit,kernel-extension,Macos,Storage,Libusb,Iokit,Kernel Extension,在一个项目中,我最近试图通过osx 10.9.5上的libusb访问usb存储设备。但很明显,一些默认的驱动程序声称该设备,我无法访问它。当我尝试通过libusb访问它时,它返回“权限不足” 当我在Ubuntu中执行(java)应用程序时,一切都正常工作 我在互联网上的研究表明,提供一个无代码的kext,在更高的probescore上匹配该设备,可以防止默认驱动程序声明该设备。这将完全解决这个问题,因为卸载IOUSBMassStorage kext使我们能够使用该设备执行所需的操作 我尝试创建一

正如它所说的kext应该是可加载的,我认为它应该可以工作。但是,当使用sudo-kextload/path/to/my.kext
加载kext时,system.log会记录这一点,而不是工作:
Nov 5 12:28:58 users-MacBook-Pro.local sudo[528]: user : TTY=ttys000 ; PWD=/Users/user ; USER=root ; COMMAND=/sbin/kextload /Users/user/Desktop/testv1-0.kext

由于这只是一个警告,我认为它已成功加载。但一旦我插入设备,usb prober输出如下所示:

这些是唯一的人格匹配发生,所以我想知道,我应该做什么,使我的kext匹配我的设备,甚至负载
kextutil
,而不是kextload
。它提供了更好的诊断IOUSBUserClient
的I/O Kit个性必须指定com.apple.iokit.IOUSBUserClient
的CbundleIdentifier
,因为该类就位于此/System/Library/Extensions
中非常感谢你!这对我帮助很大,尽管我不再使用
ioubuserclientinit
,因为我的设备是一个存储设备。你的答案仍然100%正确。
