I receive a very different error.

root@Omega-09E9:/proc# oupgrade -version

Device Firmware Version: 0.0.6 b26

root@Omega-09E9:~/test# python3 --version

Python 3.4.3

root@Omega-09E9:~/test# cat test.py
import socket
import encodings.idna
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host = socket.gethostname()
port = 9999
s.bind((host, port))

root@Omega-09E9:~/test# python3 test.py
Traceback (most recent call last):
File "prova.py", line 6, in <module>
s.bind((host, port))
socket.gaierror: [Errno -2] Name or service not known

In my case the error is caused by the fact that the hostname cannot be resolved by any DNS.

A simple solution is adding it to /etc/hosts.

root@Omega-09E9:~/test# cat /etc/hosts
127.0.0.1 localhost
127.0.0.1 Omega-09E9

@Lazar-Demin thank you!

Any news on this?

Hi @Boken-Lin !
Are there any plans to include pylibusb and one of its backends in the next firmware? (I found no mentions of it int changelogs).

Thanks.

Is that the new mini dock?

The on/off switch seems to have a perpendicular angle to the onion side.

@Boken-Lin The pyusb library supports 3 backends:

• libusb 0.x
• libusb 1.x (this one is in the Onion Omega firmware already)
• openUSB

The library has some code that needs to be compiled.

@Jarl-U-Christian-Persson It's worth to say that I'm using external USB storage [1] to install all the python3 modules available[2][3] through opkg [4].
May be you are missing some modules? double check it.

[1] https://wiki.onion.io/Tutorials/Using-USB-Storage-as-Rootfs - "option extroot with pivot-overlay"

[2] List all the python3 packages available in the repository:

opkg find '* python3 *' (remove the spaces before and after the *)

[3] List of all the python3 packages installed:

opkg list-installed | grep python3

Well I think there are 3 big sections when interacting with the onion:

1. OpenWRT (and its differences comparared to a standard linux distribution)
2. Peculiar Onion Stuff (the serial console, all its hardware and expansions - datasheets, libraries in the various languages to program them, usb and bluetooth programming, etc)
3. Breadboard and electronic components knowledge

For the next upgrade it would be nice to have the pyusb package available:
https://github.com/walac/pyusb

It is great, if not essential, to interact with the usb ports in python.

PS also pip3 python-setuptools3 would be nice.
