// Some operating systems, especially Windows, may cache USB device
// info.  Changes to the device name may not update on the same
// computer unless the vendor or product ID numbers change, or the
// "bcdDevice" revision code is increased.


// All USB serial devices are supposed to have a serial number
// (according to Microsoft).  On windows, a new COM port is created
// for every unique serial/vendor/product number combination.  If
// you program 2 identical boards with 2 different serial numbers
// and they are assigned COM7 and COM8, each will always get the
// same COM port number because Windows remembers serial numbers.
//
// On Mac OS-X, a device file is created automatically which
// incorperates the serial number, eg, /dev/cu-usbmodem12341
//
// Linux by default ignores the serial number, and creates device
// files named /dev/ttyACM0, /dev/ttyACM1... in the order connected.
// Udev rules (in /etc/udev/rules.d) can define persistent device
// names linked to this serial number, as well as permissions, owner
// and group settings.

// Mac OS-X and Linux automatically load the correct drivers.  On
// Windows, even though the driver is supplied by Microsoft, an
// INF file is needed to load the driver.  These numbers need to
// match the INF file.

// When you write data, it goes into a USB endpoint buffer, which
// is transmitted to the PC when it becomes full, or after a timeout
// with no more writes.  Even if you write in exactly packet-size
// increments, this timeout is used to send a "zero length packet"
// that tells the PC no more data is expected and it should pass
// any buffered data to the application that may be waiting.  If
// you want data sent immediately, call usb_serial_flush_output().
#define TRANSMIT_FLUSH_TIMEOUT  3   /* in milliseconds */

// If the PC is connected but not "listening", this is the length
// of time before usb_serial_getchar() returns with an error.  This
// is roughly equivilant to a real UART simply transmitting the
// bits on a wire where nobody is listening, except you get an error
// code which you can ignore for serial-like discard of data, or
// use to know your data wasn't sent.
