UDCON = UDCON & 0xFE;
The above compiles without error for an Arduino Leonardo. I'll try it in the
shop tomorrow.
Thanks!

I don't have an Arduino here that has the ATmega16U4 so I can't try this.
Perhaps someone else can?
Page 281 of the linked data sheet shows UDCON bit 0 holds the Detach Bit.
Googling access to Arduino registers implies that you can just use the data
sheet name to get to the register.
So
Atmel Studio (the free development IDE for programming Atmel/PIC AVRs
(windows only)) will import an Arduino project. This includes all the
source for all the libraries that are used. This makes it easier to
customise libraries. Programming without an ISP tool is a bit tricky - I
think you need
There are dozens of solutions. maybe the Udev rule tigers a Python scrip
that waits for an "I'm ready" signal before it makes the device? Or the
rules looks for a "myMill" device ID
I suggest reading USB documentation and standards and also how Udev works
on Linux.
This is not bad
You are correct. I have a udev rule to connect to my particular VID/PID. The
problem is trying to talk before I'm really ready.

So PP will try and "talk" to every serial port on your computer? I doubt
it is that dumb. I bet there is a Udev rule that triggers something and
you can edit the rules to look for the exact type of device or manufacturer
ID.

I don't think so when reading this from the link below, serial.dtr is not a
standard Arduino ide function:
"On a standard Arduino, the DTR and RTS signals are present on pins of the FTDI
chip, but they are not connected to anything. You can solder wires between I/O
pins and the FTDI chip if
Still requires an output. Whether it's DTR, Power, a Relay or the #RESET signal.
Page 272 and 273 talks about the DETACH bit.

It's worth a try in that blink application working with that bit to
Isn't DTR a signal controlled by the host (LinuxCNC) rather than the micro?

Hi Ken,
PJRC's version of Arduino is somewhat different, I wonder if DTR is what you
need? If you can read the serial.dtr as shown here, then I'm pretty sure you
can hold DTR low until you are ready to send/receive data:

With Arduino, the test is not to simply plug in the device. Look at
File->Examples->USB and run the sketch.
While the Arduino itself shows as a serial device, the example shows you
how to enumerate some other device, like a mouse, keyboard, or mass
storage. This would be done only AFTER the

There are lots of reasons for such random failures but in my experience they
are often the result of over allocating RAM for data and thus leaving too
