Hi!
On my computer with Windows 7 installed, everything with my Arduino Uno works fine, I can upload programs with the IDE just as expected, so I think it's at least not broken.
But on my notebook with Fedora Linux it's not working. I am using Fedora 16 with the Arduino packages from the rawhide branch [1] according to this [2] howto.
The loopback-test with pins 0 and 1 connected together worked well with a serial monitor. I have also uploaded a simple echo sketch with Windows and successfully connected with a serial monitor and it worked. The device file exists, it belongs to the group dialout which I am part of, so this should be ok.
I also have a Duemilanove clone from Itead Studio which is just working fine with Linux.
Here is the output when I try to upload with the IDE:
(Saying Error opening serial port '/dev/ttyACM0' in red over the console output)

When I try to upload a simple blink sketch with the Eclipse Arduino Plugin [3] avrdude throws this error message:
Launching /usr/bin/avrdude -patmega328p -carduino -P/dev/ttyACM0 -b115200 -Uflash:w:blinktest.hex:a
Output:
avrdude: stk500_recv(): programmer is not responding
avrdude done. Thank you.
avrdude finished
Here is the related output of dmesg:

Does really nobody have an Idea about this?
I don't think the Uno is dead because it's working with Windows. And I am able to program this Duemilanove-Clone under Linux...
...and check you have the proper permissions set in your user to access it. About a third of the way down this page, it shows what user groups you need. http://arduino.cc/playground/Linux/Fedora
I am now also a member of the uucp group but nothing changed. I was already in the dialout and lock group.
These are the permissions, they should be ok:
ls -lh /dev/ttyACM0
crw-rw----. 1 root dialout 166, 0 19. Feb 21:39 /dev/ttyACM0
The error message in the Arduino IDE remains the same.
from the folder I copied blink.cpp.hex to (which is basically the same thing the Eclipse-Plugin does) the RX-LED flashes a couple of time but then nothing else happens.
Then after a couple of seconds I get this error message:
avrdude: stk500_recv(): programmer is not responding
avrdude done. Thank you.

Are you sure the Arduino board is identified by /dev/ttyACM0 ? On my Ubuntu PCs (different versions) the serial port is always listed as /dev/ttyUSBx, where x can be 0, 1, etc.
This is what I see if I run dmesg right after pluggin in an Arduino in my laptop:

(edit: after posting my comment, I realized I skipped a really important part of the OP's post... Sorry!)
Yes, I am sure. As you have messages saying FTDI in your output I think you might not be using an Uno, are you?
As far as I know the pre-Uno Arduinos with the FTDI chip get the device file /dev/ttyUSBx and the newer ones with the 8u2 or 16u2 are filed under /dev/ttyACMx.

I saw this right after I have sent the post
The best would be if someone here was using Fedora Linux to test it, so I added it to the thred title. I hope someone will see it
Are you using the RXTX that came with the Arduino software? Or one from your distribution? By default, the RXTX software doesn't look for ACM* devices, so the one that comes with Arduino was specially modified so it does.
You might also trying symlinking /dev/ttyUSB0 to /dev/ttyACM0.
Actually, I don't know which one I am using. I just installed the arduino packages with yum, so I would rather think I'm using those from the distribution.... How can I find this out?
I hardlinked /dev/ttyACM0 to /dev/ttyUSB0 but still get the same error message from the Arduino IDE.
But I also checked it with Eclipse, which simply calls "/usr/bin/avrdude -patmega328p -carduino -P/dev/ttyACM0 -b115200 -Uflash:w:test.hex:a" for upload and it worked. What I found a bit weird is that it's now working for ttyUSB0 and ttyACM0 within Eclipse. And I was definitely unable to upload with it when I created the thread...
Correction: Damn, now it's not working again with directly calling avrdude...
Same project, same .hex-file, same USB-Port, just a couple of minutes later. What's wrong there?
