Hi,
Developing kernel extension for USB bulk and control type transfer
for Mac OS X 10.3.9 , 10.4 ppc and Intel Mac.
Some time back I posted a query for issues coming in cross-
communication of user-level with kernel level. Below is one of the
way I found out for cross communication. Please send your comments
for the same:
Since you're writing both a kernel driver and a custom user client,
could you instead use the existing USB userland APIs from your
application? The end result is the same: you'd be able to send USB
commands from your application. Leveraging services already in the OS
would save you lots of development.
Check out IOKit.framework/Headers/usb/IOUSBLib.h and related
documentation and sample code on <http://developer.apple.com/>.
