This comes in two flavors, a USB model and an Ethernet/IP model.

 device = /dev/ttyUSB0
 device =



Make sure you install the drives:

After a restart run:

 ls /dev/cu.usbserial-*

Make sure your ~/.ola/ola-usbpro.conf file matches the path above:

 device_dir = /dev
 device_prefix = ttyUSB
 device_prefix = cu.usbserial-

i.e. Look for devices at /dev/ttyUSB* , /dev/cu.usbserial-*

OLA also comes with a tool to update the firmware on a USB Pro:

 ./tools/usbpro_firmware -d /dev/cu.usbserial-0000101D -f <firmware_file>

If you're installed from source you'll need the codeless KEXT which is available here. If you installed OLA from the mac binary package this is already included.


You need a udev rule like this in /etc/udev/rules.d/10-local.rules

# udev rules file for the velleman dmx device
SUBSYSTEM=="usb|usb_device", ACTION=="add", ATTRS{idVendor}=="10cf", ATTRS{idProduct}=="8062", GROUP="plugdev"

Then make sure the user olad runs as is a member of plugdev.
