The following is a brief overview of the steps to verify that the USBETH is installed correctly—for more detailed instructions, see the PDF.
1. Download and install installer revision 2.4.1 (contains adapter driver v1.4.0) via the link below. The driver should be appropriate for the Mac OS 10.5 to 10.11 system being used.
2. After computer reboots, verify that the adapter is recognized.
- Open System Profiler. Connect ETHUSB. In USB tab, verify that the adapter appears:
3. Go to Software > Extensions and search for AX88772 in the list and verify that version 1.4.0 is installed:
4. Configure the network. Open System Preferences > Network. Select “USB Ethernet” to adjust the adapter settings. Set them to the following manual settings:
- Configure: Manually
- IP: 169.254.142.1
- Subnet Mask: 255.255.0.0
5. Adjust the network ordering such that USB Ethernet is first on the list.
a) Go to the “gear” at the bottom of the list and choose “Set Service Order” from the list.
b) In the dialog, drag “USB Ethernet” above Ethernet in the list.
c) Click OK and close System Preferences to apply the network settings.
6. Turn on the MP150 (or power cycle it if it was on).
7. Check the amber light on the ETHUSB.
- The amber light should turn on when the MP150 is on and may blink periodically but should generally be solid amber.
8. Launch AcqKnowledge.
- It should now be possible to establish communications with the MP150.
Additional Steps for Mac OS X 10.10.x – 10.11.x
- Make certain all previous steps were followed and the MP150 is connected to the ETHUSB Ethernet adapter.
- Disable all Ethernet and WiFi access. (Click the “gear” icon and choose “Make Service Inactive.” This allows the computer to locate the MP150 connected to the Ethernet adapter independently of other MP150s on the network.)
- In Mac OS X 10.11.x, make sure a gateway address is present in the USB Ethernet “Router:” field. This is due to a known 10.11.x issue where IP traffic cannot be routed unless the network has a gateway. (Enter 169.254.0.1 into the “Router” field and click “Apply.”)
- Launch the AcqKnowledge software.
- If desired, re-enable the Ethernet and WiFi access.
- If the Ethernet is enabled, the above steps may need to be repeated each time AcqKnowledge is launched. Work-arounds: • Use a direct crossover cable connection from the MP150 to the computer Ethernet port. • Establish communication via the local network without using the crossover cable or ETHUSB adapter
Additional steps for Mac OS X 10.8 – 10.9
- In section (2), the driver version will be listed as 1.4.0 if the 10.9 driver is installed.
- Add the following intermediate steps:
a) (2.5) Now the USB network interface must be added (10.9+). Open System Preferences > Network. Click on the “+” in the lower left to “Create a new service.
b) In the next dialog that appears, select the “USB Ethernet” interface and give it a default service name. “USB Ethernet” will now be available in the list in the main dialog.
c) (3.5) Unlike previous operating systems, when the cable is connected it will show up as functional with an MP150 when it has a yellow dot.
Eyes are the window to the soul and, more importantly, the brain. Psychophysiology, neuroscience, and consumer neuroscience researchers use eye tracking technology to understand emotion, behavior, subject response, decision-making, and human performance—and to help improve products and services. But not everyone knows where to start or how and why to use this important technology. A panel of eye tracking experts will present typical use cases and the latest eye tracking technology.

Solving Physical Stress Issues for Surgeons Physical stress in the operating room is common for surgeons, considering how much time they spend in an upright standing position during surgical procedures. With procedures that require standing for several hours and average reported working times of 60-80 hours a week, surgeons seem to be at risk for musculoskeletal […]
