Hi,
this isn't supported.  
More information on this topic and a workaround is to be found here:

Its a long thread, you can skip to page 2 where the real problem is tackeled ....

@biagio
You know that your code does not send any data to the device?
You have to send some register-data to the ADXL.
This is not a valid command for the device.  
Code:
Wire.beginTransmission(0x53);
Serial.print("step 1\n");
Wire.endTransmission();

Hi,

I tried my code in another computer and it works properly
How are your two machines different ?
Operating  System?

Hi,
bad news.
On the Linux-USB subsytem error 71 is a  "Protocol error".
If the error does not go away when you use a different cable or use a different USB-Port/Hub it looks like your board (the USB2Serial adapater at least) is damaged.

The FTDI driver is part of the Linux kernel. There is no need to install manually.

Hi,
when a arduino is plugged in the device /dev/ttyUSB0 will be created by the operating system, and it will be removed when the arduino is unplugged.
Test:
Unplug your arduino
Open a console window and list the current devices with
Code:
ls -all /dev/ttyUSB*
plug your arduino into your machine and list the devices again
Code:
ls -all /dev/ttyUSB*
You should now see the device created for the Ardunio.
If not, please check the system log with
Code:
dmesg
It should contain some kind of error report.

Can the IDE run properly in a win 98 SE environment?
I don't think so, I faintly remember there was someone who tried it and gave up.

There are some Linux versions (xubuntu)  that are less demanding and run on older hardware, but for laptops there have been quite often no graphics drivers available.

I almost think your old laptop is down to his knees when XP has finished booting - and the the Java Virtual machine gives it the final blow.

Minimum requirements is hard to tell. The IDE runs fine on a first generation EEE Pc (512 MB Ram) under Kubuntu. This is about the slowest machine you could buy in the last two years.

I wouldn't spend too much time on trying to make this work.

Hi,
INT0 is defined in the avr-libc include files. This is not an error caused by the Arduino-IDE.

There is obviuosly something wrong with you installation of the gcc -avr compiler and the avr-libc, because the compiler doesn't have the avr-libc headers in  the default include path.

I don't run Suse, but did your read this article?
http://www.arduino.cc/playground/Linux/OpenSUSE
If you reinstall the whole thing following the steps in the article does it work?

For what it's worth...  I have a radio (a Yaseu VX-1R) that has similar symptoms.  When the battery gets very weak the radio loses all of it's setup information.  After the battery is replaced I have to go through an extensive manual reprogramming procedure to get it working again.  (I stick to Kenwoods or Icoms now.)
The symptoms reported by the OP sound more like  
the device forgot it was a Radio in the first place   ;D

But seriously:
Is anything connected to the pins 0 and 1?
If not you could permanently pull them high with a 10K resistor.

recharged the old battery and connected it to the arduino again.  A few days later the battery was flat again and the exact same thing happened to the arduino.  
Quote
It could be that as the battery went flat there was a voltage that caused a reset, then noise on the input pins caused the boot loader to think a new program was being downloaded and it erased the flash in preparation for this, which never came.

Just a guess but it is feasible.
Ok, I would go with this story for once in my lifetime, but two times?

Maybe if the board is glued to a microwave oven or WiFi router..

Any way to do the "shift-compile-button" trick on 0016 and see what the build steps are?
Add a line with "build.verbose=true" to the arduino preferences.txt file.
This enables verbose output permanently. (build.verbose=false disables it.)

If you want to see the upload-cmds too add another line with "upload.verbose=true"

Hi,
the instructions on
http://www.arduino.cc/playground/Linux/Slackware
might cause the trouble because gcc-avr is compiled with prefix /usr/local.

I don't use Slackware, but I suggest you try to install the bin-packages  
for avr-libc, avr-gcc and avr-binutils from here:
http://www.linuxpackages.net/search_view.php?by=name&name=avr&ver=
Please report back if this was suscessful, so we can update the playground-page for this topic.
