http://askubuntu.com – I bought an arduino clone from seeedstudio (here) that should be Duemilanuve compatible. When plugging it in my system via the USB port, my system becomes unresponsive and hangs. I am running Ubuntu 11.10, 3.0.0.15-generic on a 64bit system: $ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=11.10 DISTRIB_CODENAME=oneiric DISTRIB_DESCRIPTION="Ubuntu 11.10" $ uname -a Linux lathe 3.0.0-15-generic #26-Ubuntu SMP Fri Jan 20 17:23:00 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Looking at the syslog, I see the following: Feb 29 16:47:28 lathe kernel: [ 533.732064] usb 4-2: new full speed U (HowTos)
