Ever since updating to ubuntu 11.10 rosserial won't work [closed]

edit

I am using electric on a AMD-64 laptop. I have the Arduino IDE up and it can communicate over the USB. Since updating to 11.10 rosserial doesn't work. THis is true for both diamondback and electric.

I thought it was a problem with hardware, but neither my turtlebot or arduino can talk over the USG since the system upgrade. I've don a clean install of electric. Last message states: Device reports readiness to read but device returned no data (Device discontinued)

Is this hardware software or driver? : Here is the error message:

[ERROR] [WallTime: 1354846764.670624] Tried to publish before configured, topic id 125 ^CTraceback (most recent call last): File "/opt/ros/electric/stacks/rosserial/rosserial_python/nodes/serial_node.py", line 58, in <module> client.run() File "/opt/ros/electric/stacks/rosserial/rosserial_python/src/rosserial_python/SerialClient.py", line 260, in run flag[0] = self.port.read(1) File "/usr/lib/python2.7/dist-packages/serial/serialposix.py", line 442, in read ready,_,_ = select.select([self.fd],[],[], self._timeout) select.error: (4, 'Interrupted system call')

Is the version of python an issue?
