    Default Help, want to understand mach_kernel, Extensions, *.kext.

    Hi,

    firstly i have to say that I'm a newbie and that I'm using Mac OSX just 3 days.
    I'd like to understand how Mac OSX Leopard works with the "mach_kernel" and these files and directories:

    /mach_kernel
    /System/Library/Extensions/
    /System/Library/Extensions/System.kext
    /System/Library/Extensions.mkext

    What I know is, that I can load and unload with "kextload" and "kextunload" these kexts files which are stored in "/System/Library/Extensions/", so these kexts must be some kind of modules, that could have access to the respective hardware.
    But I don't have an idea about the files "System.kext" and "Extensions.mkext".

    I'd like to know it, because I have some problems with my USB-Ports.
    The USB-Ports just works only, if the USB devices are plugged in before I start my PC.
    But when I plug in a new USB device, the divice won't be recognize from Leopard.

    And I encountered something which could be the problem.
    The version of the kernel and the version of the "Info.plist" which are stored in the "System.kext" doesn't match.

    The kernel-version:
    Code:
    clausismus-lin:~ clausismus$ uname -a
    Darwin clausismus-lin 9.2.0 Darwin Kernel Version 9.2.0: Sun Mar  2 00:35:29 SCT 2008; made by ToH:xnu-1228/BUILD/obj/RELEASE_I386 i386
    The "Info.plist" in "/System/Library/Extensions/System.kext":
    Code:
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
    <dict>
    	<key>CFBundleDevelopmentRegion</key>
    	<string>English</string>
    	<key>CFBundleGetInfoString</key>
    	<string>System Resource Pseudoextension, Apple Computer Inc, 9.4.0</string>
    	<key>CFBundleIdentifier</key>
    	<string>com.apple.kernel</string>
    	<key>CFBundleInfoDictionaryVersion</key>
    	<string>6.0</string>
    	<key>CFBundleName</key>
    	<string>System Resource Pseudoextension</string>
    	<key>CFBundlePackageType</key>
    	<string>KEXT</string>
    	<key>CFBundleShortVersionString</key>
    	<string>9.4.0</string>
    	<key>CFBundleSignature</key>
    	<string>????</string>
    	<key>CFBundleVersion</key>
    	<string>9.4.0</string>
    	<key>OSBundleCompatibleVersion</key>
    	<string>9.4.0</string>
    	<key>OSBundleRequired</key>
    	<string>Root</string>
    	<key>OSKernelResource</key>
    	<true/>
    </dict>
    </plist>
    I hope you can help.
