Hi All,

I am having a very similar problem compared with some others who have posted here previously on a Raspberry pi connected up to an NXT. I have following the installation instructions exactly including installing nxt.python (no errors), using root (on a debian machine) to install python-usb, running groupadd lego and usermod -a -G lego pi as root, setting up the file 70-lego.rules, and also configuring the .nxt-python file with the appropriate information as shown below:

[Brick]

name = 6157

host = 00:16:53:1A:9A:D5

strict = 0

method = usb = True, Bluetooth = False, fantomusb = True

I have setup .nxt-python files in both the account pi/home and also in root/home

I get the same error sequence when i run nxt.locator.find_one_brick(debug=True) as either the pi user or as a root user. Please see the attached picture.

The nxt is plugged into a USB hub, but i have tried to connect it also directly into the USB ports on the pi. Same error in both cases.

I also tried a script to find the vendor and product id:

import usb
for bus in usb.busses():
for device in bus.devices:
print device.idVendor, device.idProduct

which shows me that those values are 1682 and 2 for the NXT (since those values disappear and reappear as i plug in or unplug the NXT)
