Hi List,
I would just like to ask regarding my problem on some keyboards that I cannot get HID reports on it.
First of all, I am not the owner of the driver. I just want to connect to whatever HID devices in the system for as long as they satisfy
my condition that the Usage Page should be kHIDPage_GenericDesktop and the Usage ID is kHIDUsage_GD_Keyboard.
I am using IO Kit's API that is IOHIDManagerRef and IOHIDDeviceRef. In order for me to listen to that HID reports
of the device I register callbacks thru this API IOHIDDeviceRegisterInputReportCallback.
I can see that this is working well on the device that I developed its kext. But for the device that I'm not the developer of kext,
I have problem accessing the HID report. The callback won't work. Any known or similar issue that you've encountered before?
Thanks list. Hoping for your awesome inputs.
Rodel
