Arduino Uno not recognized

Using Arduino IDE 1.x
1

Hello,

I begin with the arduino. My problem is that everything to work first trial week, the arduino was recognized with no problem at all under Linux ( debian ). I was able to program some sketches and to test them. Suddenly, impossible to upload any sketch, then totally not recognized arduino.

The kind of message here is that sends back to me dmesg command :

[ 3071.780096] usb 4-1: new full-speed USB device number 10 using uhci_hcd
[ 3071.900105] usb 4-1: device descriptor read/64, error -71

[ 3073.840128] hub 4-0:1.0: unable to enumerate USB device on port 1

I tried to run it under Windows, the peripheral remains unknown. Even if the file of the drivers is specified for the installation, it's impossible to make it recognize.

Concerning the arduino ( Uno), the led "on" remain lit in red, and only this led is lit.

Regards.

Your Uno sounds like not genuine. And since we don't know how hardware assembled you should check components.To basic troubleshooting follow this link

http://www.arduino.cc/en/Guide/Troubleshooting#upload

And check if you can put your UNO to DFU mode

Hi,

dfu-programmer give me :

dfu-programmer: no device present.

even if I plug a jumper on the two pins.

and "lsusb" doesn't find device arduino or atmel like the tutorial of bartruffle.

Have you tried changing usb cable ? Connecting to another usb port on your computer ? What projects have you tried an your Arduino? Maybe a short circuit? You need to test components on Arduino board if you know how to do.

Hi,

Yes, I have tried changing usb cable and test anothers ports on computers but it doesn't work.

I think that it's a problem on usb port of arduino, maybe a short circuit because I have tried it with my breadboard near water at the last project...

How to test components on my arduino (especially usb port) ?

You need a multimeter, and know how to use it.
