查看usb设备信息

在 终端输入： system_profiler SPUSBDataType 可以查看连接的usb设备的信息

比如我的usb信息如下（部分内容）：

Android:

          Product ID: 0x2769

          Vendor ID: 0x22d9

          Version: 2.31

          Serial Number: 6e5d48a4

          Speed: Up to 480 Mb/sec

          Manufacturer: Android

          Location ID: 0x1d110000 / 8

          Current Available (mA): 500

          Current Required (mA): 500

查看到我的android手机的Vendor ID: 0x22d9，记住这个id

USB error 3: Unable to claim interface: Access denied (insufficient permissions)

Here is step how to do it.

1. create Info.plist in /System/Library/Extensions/Proxmark3.kext/Contents , And you should create parent folder if is missing, file content shuold be like this:

<?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">
    <!-- This is a dummy driver which binds to Proxmark. It -->
    <!-- contains no actual code; its only purpose is to     -->
    <!-- prevent Apple's USBHID driver from exclusively      -->
    <!-- opening the device.                                 -->
    <plist version="1.0">
    <dict>
        <key>CFBundleDevelopmentRegion</key>
        <string>English</string>
        <key>CFBundleIconFile</key>
        <string></string>
        <key>CFBundleIdentifier</key>
        <string>com.proxmark.driver.dummy</string>
        <key>CFBundleInfoDictionaryVersion</key>
        <string>6.0</string>
        <key>CFBundlePackageType</key>
        <string>KEXT</string>
        <key>CFBundleSignature</key>
        <string>????</string>
        <key>CFBundleVersion</key>
        <string>1.0.0d1</string>
        <key>IOKitPersonalities</key>
        <dict>
            <!-- The Proxmark3 USB interface -->
            <key>Proxmark3</key>
            <dict>
                <key>CFBundleIdentifier</key>
                <string>com.apple.kpi.iokit</string>
                <key>IOClass</key>
                <string>IOService</string>
                <key>IOProviderClass</key>
                <string>IOUSBInterface</string>
                <key>bConfigurationValue</key>
                <integer>1</integer>
                <key>bInterfaceNumber</key>
                <integer>0</integer>
                <key>idProduct</key>
                <integer>{your-usb-hardware-product-id}</integer>
                <key>idVendor</key>
                <integer>{your-usb-hardware-vendor-id}</integer>
            </dict>
        </dict>
        <key>OSBundleLibraries</key>
        <dict>
            <key>com.apple.iokit.IOUSBFamily</key>
            <string>1.8</string>
        </dict>
    </dict>
</plist>

note: {your-usb-hardware-product-id} and {your-usb-hardware-vendor-id} have to be your own hardware ids, which can be obtained from About this mac - System Report - Hardware - USB .

1. Enter /System/Library/Extensions, and run as ROOT

sudo chown -R root:wheel Proxmark3.kext

sudo chmod -R 755 Proxmark3.kext

sudo kextcache -system-caches

1. reboot your system and see the result.
