Finch Robot and USB

[nplotnick]

I have been trying to use a Finch robot (Birdbrain technologies) with Python. The robot connects to the computer via USB.

Both on a desktop and laptop running WattOS 7.5 or WattOS 8, the Python program reports that it cannot connect to the robot. I know that the USB ports are fine since I can use memory sticks and other devices. The robot works perfectly fine on a system running Xubuntu with the same libraries.

Thanks!

Hi there...I am on the road so I wont be able to look at this further until the weekend as I am currently running the still unreleased wattOS R9 which is likely not the same , but found a video on the finch and ubuntu 12.04 (which wattOS 7.5 is 13.04 and 8 is Debian) but might be worth a look. Looks like his issue was around users rights and plugdev group, and the creation of a udev file.

Not sure if its a direct match, but might be work a watch (even though he is running Unity for his desktop

If I enter SUDO PYTHON programname.py it executes fine. The issue seems to be a permission limitation on using the USB.

I think that there is a way to set SUDO level access to a particular program and not have to give my students overall access as root.

The project I am working on has me teaching them Python programming to interact with robots. I will be allowing them to use memory sticks with WattOS to boot the computers to bypass the Windows hard drives.
