Prolifics emulation (not defined) and the CDC serial implementation
(when defined). CONFIG_USBDEV_TRACE_INITIALIDSET.
examples/ustream
^^^^^^^^^^^^^^^^
This is the same test as examples/nettest, but using Unix domain
sockets.
Dependencies:
CONFIG_NET_LOCAL - Depends on support for Unix domain sockets
Configuration:
CONFIG_EXAMPLES_USTREAM - Enables the Unix domain socket example.
CONFIG_EXAMPLES_USTREAM_ADDR - Specifics the Unix domain address.
Default "/var/fifo/fifo".
