It's looking good. And that's from the reboot?

yes this is after reboot

[Reply #16 on:]

Try using sudo to run Arduino to see if it's related to permissions
not that I see why re-plugging would help if that was the case...

Is it connected to some kind of USB hub or directly to a USB port on your computer?

directly to a USB port

[Reply #20 on:]

I wonder if something else is locking the port.
Try this before starting the Arduino IDE:

Code:

ls -l /dev/ttyUSB0

Please paste the output here

And try:

Code:

cat /dev/ttyUSB0

if it shows nothing or if it shows some serial data being sent from the Arduino then it should be ok.
If something else is locing the port it would show cat: /dev/ttyUSB0: Device or resource busy

What kind of sketch is on your chip? Something that send serial data?

Code:

crw-rw---- 1 root dialout 188, 0 2012-05-08 16:09 /dev/ttyUSB0

i´ts sould be ok, i give the user right for dialout

Code:

cat: /dev/ttyUSB0: Device or resource busy

yes it send serial data as a sting but only if i send a sting to the arduino

[Reply #22 on:]

i googled abit about:

Code:

cat: /dev/ttyUSB0: Device or resource busy

i found this to find what process is accessing the arduino

Code:

sudo lsof | grep ttyUSB

but i get this error

Code:

lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/home/.gvfs

upowerd   1393       root   14u      CHR              188,0      0t0       8451 /dev/ttyUSB0

linux is so complicatet if you never use it :/

[Reply #23 on:]

The error you get is just a warning. Doesn't mean anything in this case.
What I can see is that upowerd is locking the device.

Upower is a power save component and there seems to be an old bug related to Upower and the FTDI chip: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=586751

You will have to upgrade or disable Upower to solve this but I'm not sure how to do it. As the problem is not with your board or with the Arduino environment there may be better support forums than this one.
You may have to Google a bit.

sudo apt-get remove upower

Removing it may disable support for battery monitoring (if it's a laptop) and features like suspend/hibernate. You may or may not not care about this.

thanks alot guys and special thanks to perhof it work now i update my xubuntu to 12.04. your answer about the upower bug. i google abou it and its fixed in the 12.04 thanks

[Reply #26 on:]

okey now i have another problem -.-

Code:

avrdude stk500_recv() programmer is not responding

this is what i get if i try to upload code :/

[Reply #27 on:]

A few questions:
What kind of Arduino board do you have?
Which Arduino version do you have installed on the server.
Was it when you upgraded to 12.04 that it stopped working?

[Reply #28 on:]

Code:

avrdude stk500_recv() programmer is not responding

This means that the IDE thinks you're using a specific programmer device, rather than a bootloader-based serial uploader.
You must have edited your boards file, or selected "update using programmer" in the IDE. Re-select the right board using the serial port, and you should be good to go.

[Reply #29 on:]

if i try update using programmer i get this error

Code:

avrdude: usbdev_open(): did not find any USB device "usb"

hmmm.... this is pretty annoying :/
