First time user.

Installed IDE (arduino-1.6.12-windows.exe), connected Arduino Micro to USB port. Blue LED near near connector and green LED on the component side ON.

Not recognized by computer, i.e. no update in Device Manager (Running windows 8.1).

Is it a TRUE Arduino of a copy ?
If its a copy then google CH340.

Is there anything at all with an exclamation or question mark in device manager ?
It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.

Thanks for the help!

Purchased board from Arduino LLC, 1715 Oak St Suite 1, Lakewood NJ 08701.

Nothing with exclamation or question mark in Device Manager.

How do I know if the board is a copy?

If it is a copy do I install driver for CH340?

ballscrewbob

If its a real LLC version board then you should not need the CH340 drivers.

However there have been fakes and copies.
the address you supplied didn't come up with anything Arduino so I am going to assume its a fake so yes go get the 340 drivers from HERE

Unplug any Arduinos and install the driver.
Plug in the Arduino and open up the IDE.
You will have to tell it the board type and com port which hopefully you can now see in device manager.

Let us know how you go on.

Copied the unzipped folder CH341SER  into C:\Program Files (x86)\Arduino\drivers). The files in the folder are as in attached PDF. Am I not doing it right?

Arduino Micro does not use CH340G driver and there are no "fakes" that I've ever heard of; if you have an Arduino Micro it is genuine.   You just need to use another USB cable, one that is NOT a charge-only cable.

A DJ this topic was brought up before.

There have been and are copies.

Same with the Micros.

However thanks for reminding me about the cables its something on forgot on this occasion.

I have never seen or heard of any clone or copy of the Arduino Micro.   Ever.   Of course this is a big world, so perhaps there could be one.   If somebody has a photo of one they think is a copy, and some sort of evidence it may be one, I would like to see it.

Actually I do stand corrected as the micro doesn't need a CH340 anyway....

However..
A quick EBay run brings up lots advertised as Pro Micro and Micro both with and without USB connector.
So  Guess nothing is sacred...

Pro Micro
Micro

Lots more variations too.

And of course also on Amazon

Yes, but ALL copies of ATmega32U4 boards are copies of Sparkfun's Pro Micro or Arduino Leonardo, not Arduino Micro.   There are tons of listings on sites such as eBay with incorrect titles and sometimes incorrect pictures, but what you get when you order is a Pro Micro or knock-off Pro Micro.   So in those example cases, the title indicates or mentions Arduino Micro, but the pinout shows it is actually a Pro Micro.   I don't think anybody has found value in copying the Arduino Micro, so it is a rare item in Arduino Land, a board that has not been counterfeited or cloned at all, by anybody.  Arduino Micro is the board with 34 header pins.

ballscrewbob

Exactly...
Which always begs the question is it a real one of does somebody THINK they have a real one and with such mis-label of almost all the boards on EBay and Amazon and even in some of the smaller actual retail shops that get stock from China it is no longer an unfair question to ask regarding drivers.

Hence I asked for a link but when that link turned up "perfume" ... I smelled   :)  not a genuine article and possibly something else.

Used a brand new cable (USB 2.0 A male to micro USB 5 pin male cable from i dot Connect) - but same problem.
BTW I bought an UNO with the Micro - UNO seems to work.
The Micro silk-screen says Arduino Micro - do not know if that means anything.

dmjlambert

I suggest use a micro USB cable that is known to work for data with another device, such as a cell phone, Kindle, or some other thing that will show the cable works for more than just charging.      Or contact the seller for a replacement Micro.   If you are adventurous, use the Uno as an ISP programmer and burn a fresh bootloader on the Micro.   To do that you would find a tutorial online that talks about ISP programming using the ArduinoISP sketch and in the Tools, Programmer menu select programmer type "Arduino as ISP".

Thanks - these are all useful suggestions
