[原]OS X 10.9 Mavericks - Virtual Serial Port Issues

If want to do iOS kernel debugging on A4 device,

first you should install Virtual COM port (VCP) drivers.

After has installed the driver on OS X Mavericks, 

plugin your device (for examle: iPod Touch 4, WiFi),

then execute the following command:

ls /dev/tty.usb*

Sadly, can't find the device.

Following the steps to fix this issue:

Step 1: Install VCP Driver.

Step 2: Unload the driver: sudo kextunload /System/Library/Extensions/FTDIUSBSerialDriver.kext

Step 3: Edit driver Info.plist: 

cp /System/Library/Extensions/FTDIUSBSerialDriver.kext/Contents/Info.plist ~/Desktop/

open the plist file with xcode,

extend the IOKitPersonalities key,

copy an existing item, for example: iPod Serial Port,

and change vendor and produnt id for your device, for example :iPod Touch 4, WiFi, VID is 1659, PID is 8963,

save the plist file,

and then 

sudo cp -f ~/Desktop/Info.plist /System/Library/Extensions/FTDIUSBSerialDriver.kext/Contents/

Step 4: Load the driver: sudo kextload /System/Library/Extensions/FTDIUSBSerialDriver.kext

Step 5: view device: ls /dev/tty.usb*, you will see it

The Key Point:

Rules Of Driver Best Match: Product ID & Vendor ID.
