Use a powered USB hub. The available current from the RPi board USB is quite low.

Maybe your RPi power supply isn’t up to it? Try a different power supply too.

Subject: [open-lighting] Raspberry Pi+Enttec openDMX usb

 

today I downloaded the raspbian-ola-0.8.26 image and I tried it on my new raspberry pi. It works perfectly if there isn't connected my Enttec Open DMX usb interface. As soon as I connect it to raspi, the raspi crash: "_" doesn't blink, any input command is received. If Enttec open usb is connected before powering on raspi, it can not complete the boot.
Is there a way to use Raspberry Pi + OLA + Enttec opendmx?

I was unable to get my Enttec open DMX USB to work without crashing the rPi, no matter what.  Powered hub, beefy power supply, none of it made any difference.  Same symptoms as you describe.  I ended up just getting a DMXking USB micro instead.

Excellent choice, I use my open as a paperweight.

So did I.  2 amp D-Link 7-port powered hub, with only the Enttec plugged into it.  Still crashed my pi every time.

The RPi has a problem with USB-to-serial adapters like the chips from
FTDI. You could try the patch posted here:
https://github.com/raspberrypi/linux/pull/195#issuecomment-12443840
and tell us the results then

I had the bare board version, which I believe is internally the same. I never had any problems with it on the rPi with a powered USB hub. Worked pretty much straight away. I use it with an rPi hosted web server to control some lights.

I compiled ola from source on one of the standard debian images on it; I don't think that should matter much, though.

Aren't the Debian images not optimized for armv6?  Isn't that why we have raspbian?

So why would one use the Debian images over the Raspbian ones? Is there something compelling about vanilla Debian over Raspbian?

I managed to make the system work. I don't know why, but it works. Below are the isntructions.

#I download and install the following image:

2012-12-16-wheezy-raspbian.zip

#start “putty.exe”

#using “putty” you can control the raspi, but you must know the IP address, in my case it was 192.168.0.8

login as:  pi

p...@192.168.0.8's password: raspberry

sudo nano /etc/apt/sources.list

# add the following line:

deb http://apt.openlighting.org/raspbian wheezy main

# save typing crtl+O

#exit typing crtl+X

sudo apt-get update

sudo apt-get install ola

#Optional:

sudo apt-get install ola-python ola-rdm-tests

#During installation is required, if we prefer start OLAD on boot. Choose yes, but you can change also in a second time the choice with the following command:

sudo dpkg-reconfigure ola

#Add the user “pi” to olad

sudo adduser pi olad

#Reboot the raspi

#start “putty.exe”

login as:  pi

p...@192.168.0.8's password: raspberry

sudo apt-get update

sudo apt-get install ola-conf-plugins

ola_conf_plugins.sh disable all

ola_conf_plugins.sh enable ftdidmx

ola_conf_plugins.sh enable artnet

#Connect the Enttec OpenDMX to raspi.

#Reboot raspi

#Using the browser go to the address of your raspi, in my case:

http://192.168.0.8:9090

#Now you can set the raspi+OpenDMX USB as an ArtNet node with a single DMX universe.
