Hello,
How i may do to send data via a controlrequest and get echoe on a pipe via Readpipe in a alternative way ? Actually, i use 2 process but i obtain an 10000003 error on my child process (readpipe).

Since mach ports (used to implement the user-mode USB interfaces) are not copied to child processes, and only one process can have a single USB interface open, you would probably be better to architect your application using pthreads instead of multiple processes.
