Where to start USB Development?

[shad0w]

Hi folks,

I'm new to apple usb development. I got an USB Voltmeter and want to read the data from the device into my iBook.

Where do I get information about usb and apple? I read the usb hid specifications from usb.org and got some information from developers.apple.com, but this wasn't very useful.

thanks in advance

See:

http://developer.apple.com/hardware/usb/index.html

There's information on that page for loading debugging kernel extensions, using the USB prober application, how to write for IOKit, etc, etc. I think you'll find what you need there.
