Hi!

I recently bought a Arduino Leonardo board.

I am now trying to upload programs with the Arduino IDE (1.0.1) on Fedora 17, 64bit.

When I plug it in, dmesg reports this:

Code:

[144825.697050] usb 3-1: new full-speed USB device number 14 using uhci_hcd

In the IDE I chose /dev/ttyACM1 as serial port. I guess, that's correct.

When I open the seriel monitor in the IDE, it reseivces "TESTATA" on this port.

BUT, if I try to upload my program, I get this error:

Code:

processing.app.debug.RunnerException: Couldn’t find a Leonardo on the selected port. Check that you have the correct port selected.  If it is correct, try pressing the board's reset button after initiating the upload.

I found that someone here:

http://arduino.cc/forum/index.php?topic=127009.0

Has the same problem, but also didn't find a solution.

I also downloaded the Arduino IDE from the Arduino website and tried to it with it, but it also reported this error:

Code:

processing.app.debug.RunnerException: Couldn’t find a Leonardo on the selected port. Check that you have the correct port selected.  If it is correct, try pressing the board's reset button after initiating the upload.

Could this be a udev problem? Because it seems to connect as a Mouse.

What am I doing wrong?

Thanks

Kind regards

I think the problem is, that it first connects correctly as

cdc_acm 3-1:1.0: ttyACM0: USB ACM device

but then after a few seconds:

get's recongnized has HID device:

[  322.722263] input: Arduino LLC Arduino Leonardo as /devices/pci0000:00/0000:00:1a.0/usb3/3-1/3-1:1.2/input/input17

Does anyone know how to fix this in udev or so?

I tested it on Ubuntu on the same laptop and there I could upload the program, but dmesg also showed this:

Code:

So is it maybe a different problem?

I have found the problem.

The problem is: ModemManager.

You can see the process "modem-man" if you run "sudo lsof /dev/ttyACM0" right after you plugged in the Arduino Leonardo.

So I solved the problem by:

Code:

systemctl stop NetworkManager.service

and

Code:

sudo killall -TERM modem-manager

After that I could upload the program.

To fix this permanently, you can edit

/etc/udev/rules.d/77-mm-usb-device-blacklist.rules

and add:

Code:

# Arduino
ATTR{idVendor}=="2341",  ENV{ID_MM_DEVICE_IGNORE}="1"
