Hello to all,

I've two Arduino NANO 3.0.
One of them is not more recognised after some hours without problems.

On dmesg I obtain:

Code: [Select]

Jan 18 22:54:34 x3fi-book kernel: [ 3144.056064] usb 2-2: new full speed USB device using uhci_hcd and address 77

Jan 18 22:55:26 x3fi-book kernel: [ 3195.144072] usb 2-2: new full speed USB device using uhci_hcd and address 108
(...)


I'm using Ubuntu 10.10.

One time it was recognised for not more than one second and then disconnected again:

What could be the cause?
The other arduino works.
Maybe It's something not correctly working? Some parts not well connected?

Are some tests I could try?
Now I'm on a Ubuntu at home. Depends on where I'm (home or work) I can test on a Windows.

Thank's forany help!

Simon
