| Hi everyone,
I want to adapt the sample MIDI USB driver to make a driver for a custom MIDI controller device.
It look to the operating system as a HID device.
Right now i have acomplished the objective of reading from the device using HID manager.
I've been looking to SampleUSBMIDIDriver code and it seems that it receives a handle to a USBDevice:
bool SampleUSBMIDIDriver::MatchDevice( USBDevice * inUSBDevice) {
Can i change the argument type of the driver constructor and functions to HidDevice?
Will it then be called when it supposed to?
I would like to have more information on how Mac OSX calls the drivers to understand what i have to do.
Can anyone give me a lights on this or point me to usefull documentation about this particular issue?
Thx,
With my best regards,
Nuno
