 Bigger Bigger  Smaller Smaller  Reset Reset

Hi, first post here.

Just had my first Arduino, a Leonardo.
Cant get the usb drivers on windows.
I get the message 'windows was unable to install your arduino leonardo bootloader'

The device is listed in device manager under \ other devices \ arduino leonardo bootloader.

Hope you can help me get over this first hurdle

You should be able to install the driver for this device by pointing to the Arduino\Drivers folder.

Right click the device in Device Manager \ Other Devices
Select Update Driver Software
Select Browse my computer for software
Click Browse button
Select the Drivers folder under the location of your Arduino software installation
Click OK
Click Next

Thanks Louis

I can get to your Click OK step but windows says

windows was unable to install your arduino leonardo bootloader
windows could not find driver software for your device

before I can get to Click Next step

I know I will look back in this with amusement when I work out what is wrong but right now its been four hours of frustration.

What version of the IDE do you have?
It needs to be 1.0.1: http://arduino.googlecode.com/files/arduino-1.0.1-windows.zip

Make sure you are selecting the Drivers folder(see attached image)

Yes version and method just like your instruction.

Device manager adds two devices that I can see when the Leonardo is connected.

Device Manager \ Other Devices \ arduino leonardo bootloader
The drivers for this device are not installed. (Code 28)
this has the yellow ! and is what I try to install drivers for.

Device Manager \ Human interface devices \ USB input device
This device is working properly.

It looks like you must have an older version of the bootloader because the Arduino Leonardo.inf file is looking for:
USB\VID_2341&PID_0036

It looks like Arduino IDE 1.0 has the Arduino Leonardo.inf that has that hardware ID.

Since I am not that familiar with the Leonardo, I am not sure the bootloader on your board is compatible with the 1.0.1 IDE.

I have seen mention in the forum that the Leonardo bootloader changed just before the official release.

Hopefully someone else can step in a clear this up.

Thanks Louis, you seem to have found my problem pretty fast, I was sure it was me doing something sooo stupid.

Not sure what the boot loader is, boot loader is initiated at run time from firmware maybe.

I have just been surfing and discovered there are different (clone) Leonardo on the market.
I had mine from http://www.olimex.com/dev/olimexino-32u4.html

At the bottom of the above page it mentions

Latest BOOTLOADER for ARDUINO IDE 1.0.1

I down loaded 1.0.0 and the usb drivers are installed  smiley-mr-green

Arduino Leonardo on com 3

No Leonardo in the board choice though so will put 1.0.1 back on and see what happens





So 1.0.1 back and tried to upload blink, failed a few times giving

avrdude: ser_send(): write error: sorry no info avail

So I guess I need to burn the updated boot loader, might need some direction on this.

Many thanks

Bemused, if you're using an Olimex board, you should ask them for help.  Unfortunately, we can't support other people's products (because we don't know how they work, etc).

Ok so I just ordered an official Leonardo from one of your links, this will come with a 1.0.1 compatible bootloader I expect.

From this new standpoint I will be able to re-flash the the hooky Leonardo via the official working Leonardo?

Many thanks

So I found the Leonardo board commented out in the
c:\arduino-1.0\hardware\arduino\boards.txt” file

I removed the comments, Leonardo appeared in the boards menu and we are away having a little fun.
