Canon Pixma Driver For Mac
Paragon Driver For Mac
The Questions:
Has someone allready done this? For this device? Which device does it work on?
I don't know.
Why did microchip call a chip programmer a HID device?
It is one of the easiest ways to implement a simple USB device. Whether it has buttons, wheels or indicators on it is irrelevant. It can be something other than a mouse or keyboard.
Why did the apple HID framework attach the device when it has no HID compliant controls?
The device presumably declares itself to be a HID class device. Therefore it gets the HID driver.
Can I get the Apple HID controls to release the programmer or not to attach at all?
(or) I have to write a kext/driver stack to match the vendor/product/model exactly to force the point?
Yes. You need a 'codeless kext' to match vid/pid of the device. The basic idea is to make a 'driver' with no executable, so the system's kernel HID driver doesn't match against the device. This gives your userland driver a chance.
See lists.apple.com and search the USB development list for more.
hope this helps, Stuart

- Back in the Device Manager, you should see a new category called Microchip Tools with Microchip WinUSB Device listed under it. The driver will show the same name for the REAL ICE and the ICDs. The driver will show the same name for the REAL ICE and the ICDs.
- This is a cross platform project that is similar in functionality as the 'WinUSB PnP Demo - PC Application - MS VC++ 2008 Express' project. However, this version is developed in the Qt development environment (from qt.nokia.com), and uses the 'libusb v1.0' APIs.
