This cocoa-dev list is probably the wrong list for these types of
questions, you should join the Apple USB mailing list. Also did you
try the MacOSX USB DDK via:
ftp://ftp.apple.com/developer/Development_Kits/Mac_OS_USB/USB1.8.2SDK.pkg.sit
There is an example of talking to an Anchor based USB device. You
should be able to achieve what you want to do by using the userclient
API's in your coca App.

Roger,
I want to access a USB device, based on the Cypress / AnchorChips EZ-USB
chip, such as described in Apple's document "Working With USB Device
Interfaces". Could the example code, starting on page 11 of that document,
be implemented as a Cocoa app? Or could the example, as is, be wrapped by a
Cocoa front-end? A simple goal for my project would be a single-document
app showing three buttons, "1", "2", and "3". Clicking on a button would
cause a USB Bulk OUT transfer of the corresponding numeric value to the USB
device.
Thanks
Bill

You have to be more specific in your goal, what is your hardware and
what are you trying to do. Are you writing the driver and App
yourself and need to communicate between them? Are your trying to
talk to a serial port? Depending on your needs there are slightly
different approaches..
