I think the state of documentation and samples is pretty bleak right now. The one bright spot is Apple's <a href="http://developer.apple.com/samplecode/HID_Utilities_Source/HID_Utilities_Source.html" rel="nofollow">HID Utilities</a> sample code, which I suggest using instead of trying to deal directly with the IOHIDLibrary. It has some rough edges but definitely takes care of some dirty business for you. Things got a lot easier conceptually when I discovered George Warner's (one of Apple's excellent DTS staff) <a href="http://mud.5341.com/msg/8455.html">high-level overview of HID Utilities</a>. I spoke with George and apparently they are planning to include more high-level descriptions like this in future releases of HID Utilities. One of these days I might get around to writing a sort of "HID For Dummies" introduction to help future "people like us" out :) Hi Richard – thanks for stopping by.

I stumbled across your blog today when I was Googling Mac OS X HID development. I am also just starting development of a custom HID device, you can think of it as a terminal application where I'm sending bulk data in and out a USB port. I am new to Mac programming and finally starting to get my feet under me with the USB interface. Where would you suggest I start on this HID development? Do you have any sample code you would be willing to share? Keep up the great blog! I'm glad I found it! Hi Daniel! I stumbled across your blog today when I was Googling Mac OS X HID development.

Heck, I get nervous when I see a *decrementing* loop. I tend to add parentheses too, rather than trust my knowledge of operator precedences. Parens are also handy because I can double-click to highlight the entire delimited expression, which makes it easier to walk through non-trivial boolean expressions.

Hopefully for the freezing issue I will end up writing a bug report to myself instead of Apple (but it's not looking hopeful!)...

Pretty cool you could get the source for this and figure it out. I am with you though, I would always do the unsafe thing out of the loop so it was clear.
