New Arduino UNO R3 not recognized by Win XP SP3 or Ubuntu 12.04

Hello all,
I received my Arduino UNO R3 yesterday and after long hours of research and attempts to try to install it, I am about to pull my hair out. :slight_smile:
I installed the Arduino 1.0.1 for both O/Ss: Win XP SP3 and Ubuntu 12.04. On the Win computer, the IDE works fine, but the board is never recognized when plugged in (even though the Green LED is on and the orange for pin 13 flashes), so I am not able to complete the Arduino instructions to properly install the drivers. After 4 frustrating hours trying on Windows, I decided to install the IDE on my Linux O/S (same computer, BTW). The program installed without problems, but the Serial Port is grayed out. I already tried checking the groups, I am added. Also when I check the devices: ls /dev/, only my USB mouse receiver is recognized and never my UNO. I don't know what else to do. If I can make it work in one of the operating systems, I'll be a happy camper.

Please help! I will appreciate it immensely!

What this command output if when running in a terminal

lspci

or dmesg

Did you try a different cable?

Can you try this in Windows: http://arduino.cc/forum/index.php/topic,118440.0.html

If still does not work, probably it is something with the small chip that handles the communication, so if the arduino is new, easy way: return it.

THANK YOU ALL FOR YOUR REPLIES.

It works! I am not sure what happened because the only thing I did after posting the original post was to run the lspci command HugoPT posted, so thank you! :~

@eried - I installed the ERW this morning, It is definitely better.

Thank you all again!

I'm having the same problem. Arduino board won't install on my Windows XP. Where am I supposed to type in the code "lspci" a previous poster wrote?
Thanks.

That is for linux, try http://arduino.cc/forum/index.php/topic,118440.0.html

I ran into a similar issue with Windows 7 64-bit and Arduino 1.0.3. I have an Uno R2 board and an Uno SMD R2 board and they work fine. My PC would not recognize the new Uno R3.

After a little diving in the arduino/reference/Guide_Troubleshooting.html document that comes with the IDE I found this:

On Windows 7 (particularly the 64-bit version), you might need to go into the Device Manager and update the drivers for the Uno or Mega 2560. Just right click on the device (the board should be connected to your computer), and point Windows at the appropriate .inf file again. The .inf is in the drivers/ directory of the Arduino software (not in the FTDI USB Drivers sub-directory of it).

In doing so, my Uno R3 is now recognized and working as expected.
