I am working on a requirement where i need to monitor changes in Thunderbolt port connection. (When Thunderbolt cable is connected or disconnected). I tried to use IOServiceMatching(kIOUSBInterfaceClassName) from IOKit framework but i cannot monitor changes on Thunderbolt port. Is there any way i can achieve it? Any help is appreciated. Thunderbolt devices (except displays that use the DisplayPort portion of the Thunderbolt port) are PCI devices, not USB, so they will show up in the IOService registry as IOPCIDevice s. They will however also show up as IOThunderboltPort objects in the

I have minimum exposure to xcode and I/Okit framework. I have seen device descriptor and configuration descriptor of a usb device in USB prober. I have written an xcode program using I/O kit framework which gives the usb device name as output, when we give product id and vendor id of that device as input. /*Take the vendor and product id from console*/ printf("\nEnter the vendor id : "); scanf("%lx",&usbVendor); printf("\nEnter the product id :"); scanf("%lx",&usbProduct); /* Set up a matching dictionary for the class */ matchingDict = IOServiceMatching(kIOUSBDeviceClassName); if (matchingDict

I'm trying to change the mouse tracking speed (Notice: Not acceleration) for an application I'm working on. I've searched everywhere for a way to do this, but couldn't find anything. I suspect that has to do with the value I give in this function on the IOKit/hidsystem Framework: IOHIDSetAccelerationWithKey(handle, CFSTR(kIOHIDMouseAccelerationType), mouseAcceleration); Being mouseAcceleration the value, I suspect there is a hex value that defines both acceleration and speed. Does anyone came across this problem and could help me? Thanks in advance Working example in swift: func

The following code works perfectly to get a list of connected HID devices: import Foundation import IOKit import IOKit.usb import IOKit.hid private func createDeviceMatchingDictionary( usagePage: Int, usage: Int) -> CFMutableDictionary { let dict = [ kIOHIDDeviceUsageKey: usage, kIOHIDDeviceUsagePageKey: usagePage ] as NSDictionary return dict.mutableCopy() as! NSMutableDictionary; } let manager = IOHIDManagerCreate(kCFAllocatorDefault, IOOptionBits(kIOHIDOptionsTypeNone)); let keyboard = createDeviceMatchingDictionary(usagePage: kHIDPage_GenericDesktop, usage: kHIDUsage_GD_Keyboard)

I'm currently working on a Backup Application, and I have received a lot of requests for features to be added recently, and the top one of them is adding a checkbox like "Back Up when on Battery Power" like Time Machine has. So, is there a way I can get the status of the Power Adapter (plugged in and plugged in)? I assume that if one had a Desktop Mac, like iMac, etc, I would probably just get Plugged In all the time. Therefore, I need means of detecting if the computer is a portable or not. I assume IOKit would be a library to look at, but I simply could not find anything in the docs, that

I'm playing with IOKit and have the following code, the general idea is to pass a platformExpert key to this small core foundation command line application and have it print the decoded string. The test case is "serial-number". The code below when run like: ./compiled serial-number Almost works but returns the last 4 characters of the serial number at the beginning of the string i.e. for an example serial such as C12D2JMPDDQX it would return DDQXC12D2JMPDDQX Any ideas? #include <CoreFoundation/CoreFoundation.h> #include <IOKit/IOKitLib.h> int main (int argc, const char * argv[]) { CFStringRef
