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 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”

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