I'm trying to get a Roomba 555 with Turtlebot power board to work, but keep getting the following message:

"Failed to contact device with error: [Error reading from SCI port. No data.]. Please check that the Create is powered on and that the connector is plugged into the Create."

I connected the Turtlebot to a Dell Inspiron 6400, running Ubuntu 10.04 and ROS diamondback. My serial device looks like this: crw-rw-rw- 1 root mate 188, 0 2011-11-03 10:48 /dev/ttyUSB0

As listed in lsusb: Bus 004 Device 006: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC

I've tried the traditional fixes, such as restarting, unplugging-replugging, looked at dmesg, but no clues.

Any ideas how I could fix this would be very much appreciated. Thanks in advance, Máté

Check that the iRobot Create is turned on. ( The green light should be on next to the power button.)

Hi ROS community ! I have the same problem here, on an eu turtlebot 1 (based on roomba 521). I think is correctly turned on and i can see the ttyUSB0 file in /dev. I think is cause of the board, it's an old turtlebot.eu card on which I can't find any information on the internet.

Thx !
