 Bigger Bigger  Smaller Smaller  Reset Reset

Hi
I'm currently trying to get all my boards up and running on my new Linux systems.
I have successfully uploaded to 2 UNO's, 2 MEGA2560's, 1 Mega ADK and 2 of my Duemilenova's (for detail http://arduino.cc/forum/index.php/topic,151242.msg1135852.html)
When I tried a leonardo I see nothing happening on my system.
After I disconnected my duemilenove's and connected my leonardo dmesg tells me
Code:
bash-4.1$ dmesg | tail
FIREWALL: IN=eth0 OUT= MAC=00:26:2d:ff:c8:5c:11:00:06:8b:05:d6:08:00 SRC=23.62.99.19 DST=192.168.1.2 LEN=1492 TOS=0x00 PREC=0x00 TTL=57 ID=31953 DF PROTO=TCP SPT=80 DPT=41427 WINDOW=7776 RES=0x00 ACK URGP=0

usb 2-1.2: USB disconnect, device number 15

ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0
ftdi_sio 1-1.1:1.0: device disconnected
usb 2-1.1: USB disconnect, device number 14
bash-4.1$
I disconnected and reconnected it again and the dump above is from the second command. (note that the fact that the 14 gives a little different message is probably caused by the fact this one was connected to my vm)

When I look up information on getting leonardo work on Linux I find "Thee is nothing to do. I just works"
I have no clue where to go and look for problem solving. I tried nearly all commands on http://playground.arduino.cc//Linux/Fedora but nothing helped.

Hopefully someone can help me

I made some progress.
I replaced the usb cable  smiley-red. That makes he Leonardo more responsive but still not visible in Arduino IDE 1.5.2 or 1.0.3  (also not as root )
The output of dmesg |tail
Code:

bash-4.1$
you can clearly see the first port opening and closing and then he second port opening.
But I do not see an assignment to a usb port like with a uno.
Any help is appreciated.

Nice to see the progress you are doing, I'd be glad to help but I don't have a linux box available at the moment. But from the log it seems you should see a /dev/ttyACM0 device when the Leo is connected: aren't you seeing it?

Spatula
Thanks for the reply
I checked but no such device
Code:
bash-4.1$ ls -l /dev/ttyA*
ls: cannot access /dev/ttyA*: No such file or directory
bash-4.1$
The ttyACM0 is created on the first connection (108) which is immediately closed.
I see no device name on the second connection (109) so I don't have a clue what to look for.

If you wonder about the big number...
I found that running vmware makes the leonardo connect and disconnect al the time (sounds like mario when you run windows in the vm ;-) )
Each time the number gets raised twice (once for each port)
As you can see from the following dump
Code:
bash-4.1$ dmesg | tail -100

This reconnection does not happen with the micro on my system. But I do not know the port for the micro as well (so no upload on micro in linux for me right now)

I still didn't get this to work.
lsusb sees the arduino
Code:
bash-4.1$ lsusb

I have created 99-arduino.rules with following content
Code:
SUBSYSTEMS=="usb", ATTRS{idProduct}=="8036", ATTRS{idVendor}=="2341", SYMLINK+="ttyUSB%n" , MODE:="0666"
This makes that the ls -lrt /dev/ttyU* returns following
Code:
bash-4.1$ ls -lrt /dev/ttyU*
lrwxrwxrwx. 1 root root 15 Mar 29 23:02 /dev/ttyUSB2 -> bus/usb/002/052

lrwxrwxrwx. 1 root root 13 Mar 29 23:02 /dev/ttyUSB14 -> input/event14
bash-4.1$
If I unplug the Leonardo all these ports disappear.
I do not understand why there are 4 USB ports and why non of them are recognized by the Arduino IDE as Arduino Ports.
These USB ports do not seem to be serial ports
Code:
bash-4.1$ ls -lrt /dev/serial
ls: cannot access /dev/serial: No such file or directory

 Bigger Bigger  Smaller Smaller  Reset Reset

Hi,
since the Leonardo can emulate a mouse or a keyboard the additional input devices are normal. I have them as well, but I also have /dev/ttyACM0. Any chance that other VMs on the same host (if not the host itself) are trying to install the USB device? This could explain the disconnections/reconnections you experienced before.

I don't have VMware but a couple of small VMs on VirtualBox, my host is a Mac and one VM has Lubuntu 12.10. In VirtualBox I have to assign to the VM not just the USB port, but a particular USB device (recognized as Leonardo by the host). This tells me that before I can use it on a VM the device must be recognized by the host. It may be different in VMware but may be worth of attention (can you determine if the host OS sees the Leonardo?).

Finally, here is my dmesg after plugging the Leonardo. You'll notice that I have a different version of usb, use uhci_hcd instead of ehci_hcd, have cdc_acm create the ttyACM0 device (twice), and have one disconnection before the connection is established. This corresponds to the normal mode of operation of Leonardo: the first connection is for accessing the bootloader, then for normal operations the port is reset (just once) and the devices are created.

Thanks for helping out.
since the Leonardo can emulate a mouse or a keyboard the additional input devices are normal. I have them as well, but I also have /dev/ttyACM0. Any chance that other VMs on the same host (if not the host itself) are trying to install the USB device? This could explain the disconnections/reconnections you experienced before.
Thanks for confirming the additional devices. I do not have a /dev/ttyACM0 which seems to be the problem at hand.
As I'm running Linux native (I run XP in a vm) I have stopped all vm's and the vmware software and tried again. As you can see from the logs below that results in exact the same behaviour.

I don't have VMware but a couple of small VMs on VirtualBox, my host is a Mac and one VM has Lubuntu 12.10. In VirtualBox I have to assign to the VM not just the USB port, but a particular USB device (recognized as Leonardo by the host). This tells me that before I can use it on a VM the device must be recognized by the host. It may be different in VMware but may be worth of attention (can you determine if the host OS sees the Leonardo?).
The assigning of USB devices is exactly the same with VMware. If I assign the Leonardo to my windows xp VM machine it works fine.
As my host OS is Linux the host OS does see the Leonardo because A) it can assign it to a vm and B)dsmeg and lsusb see the device.

Finally, here is my dmesg after plugging the Leonardo. You'll notice that I have a different version of usb, use uhci_hcd instead of ehci_hcd, have cdc_acm create the ttyACM0 device (twice), and have one disconnection before the connection is established. This corresponds to the normal mode of operation of Leonardo: the first connection is for accessing the bootloader, then for normal operations the port is reset (just once) and the devices are created.
Thanks for sharing your dmesg output. My dmesg looks very similar except for the second connection does not result in a ttyACM* device.
Code:
bash-4.1$ dmesg | tail
usb 2-1.2: new full speed USB device number 55 using ehci_hcd
usb 2-1.2: New USB device found, idVendor=2341, idProduct=0036

It looks as if udev does not recognize the leonardo com port. It seems as if the ACM port is not identified by
Code:
SUBSYSTEMS=="usb", ATTRS{idProduct}=="8036", ATTRS{idVendor}=="2341"
but that is the only consistent info I see in lsusb and dmesg.

Could you provide me with the outcome of the following commands (when Leonardo connected off course)
Code:
ls -lrt /dev/serial
Code:
ls -lrt /dev/ttyA*
Code:
ls -lrt /etc/udev/rules.d/
Code:
grep 2341 /etc/udev/rules.d/*
Thanks

Here are some answers:
Code:
/dev/serial/by-id:
total 0
lrwxrwxrwx 1 root root 13 Mar 30 21:47 usb-Arduino_LLC_Arduino_Leonardo-if00 -> ../../ttyACM0

/dev/serial/by-path:
total 0
lrwxrwxrwx 1 root root 13 Mar 30 21:47 pci-0000:00:1d.0-usb-0:2:1.0 -> ../../ttyACM0

crw-rw---- 1 root dialout 166, 0 Mar 30 21:47 /dev/ttyACM0

I have no usb-related stuff in /etc/udev/rules.d/, just the default 70-persistent-cd and 70-persistent-net, and none of them contain 2341. I also noticed that in /lib/udev/rules.d/77-mm-usb-device-blacklist.rules the Arduino devices are mentioned at the bottom of the file (this should prevent them to be taken by modem-manager).
Code:
# Arduino devices, FT-232-based series and Atmega8U2 (Uno)
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ENV{ID_MM_DEVICE_IGNORE}="1"
ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="204b", ENV{ID_MM_DEVICE_IGNORE}="1"
ATTRS{idVendor}=="2341", ENV{ID_MM_DEVICE_IGNORE}="1"

I forgot to mention (just for completeness, it doesn't seem to make much difference) that the dmesg of my previous post comes from a PC with native Lubuntu 12.10, while the same on the Lubuntu VM only shows the second connection (the first connection is managed by the host OS). All the rest (devices, rules, lsusb output) are the same.

thanks for the response
It seems the Arduino specific settings on our systems are pretty much the same. Unfortunately for me it doesn't work on my system.
I'll have a search on usb-Arduino_LLC_Arduino_Leonardo-if00 and pci-0000:00:1d.0-usb-0:2:1.0
Thanks for sharing that you have arduino in the 77-mm-usb-device-blacklist.rules file. With your explanation I know why smiley-grin
I have that one to; but removing didn't make a difference.
My current thinking is that I have to look for a disable rule.
Thanks

Try:

echo "0x1b4f 0x9204" > /sys/bus/usb/drivers/cdc_acm/new_id

That should get you the /dev/ttyACMx port.

The cdc_acm driver in newer versions of linux (like Ubuntu 13.04) work fine, but older versions need the above command (or some UDEV wizardy) to enable the port.

I just see your comment now.
I tried that. Didn't help.
Sorry.

Is your Leonardo programmed to be something other than a serial device. If so then what you see maybe normal. When the bootloader shuts down if it is a mouse, say, mice don't have serial ports. Try and upload blink, or something, from the IDE by pressing the reset button at the end (or just before the end) of compilation. Can you reprogram the Leo  to have serial output? Then you should see it enumerate as a ttyACM* port, both times.

Maybe get rid of the udev rule, it may be confusing things.
Code:
Here's what my kernel log shows when a leonardo, as a mouse, is plugged in.
usb 3-4: new full speed USB device using ohci_hcd and address 31
usb 3-4: configuration #1 chosen from 1 choice
cdc_acm 3-4:1.0: ttyACM0: USB ACM device
usb 3-4: USB disconnect, address 31
usb 3-4: new full speed USB device using ohci_hcd and address 32
usb 3-4: configuration #1 chosen from 1 choice
cdc_acm 3-4:1.0: This device cannot do calls on its own. It is not a modem.
cdc_acm 3-4:1.0: ttyACM0: USB ACM device
input: Arduino LLC Arduino Leonardo as /devices/pci0000:00/0000:00:02.0/usb3/3-4/3-4:1.2/input/input23
generic-usb 0003:2341:8036.0014: input,hidraw3: USB HID v1.01 Mouse [Arduino LLC Arduino Leonardo] on usb-0000:00:02.0-4/input2
usb 3-4: USB disconnect, address 32

Hope this helps.
