3.4.2 ALP Does Not Detect the EVM

If the following window opens after starting the ALP software, double check the hardware setup.

It may also be that the USB2ANY driver is not installed. Check the device manager. There should be a HID-compliant device under the Human Interface Devices as shown below.

The software should start with only DS90UB95x in the Devices drop-down menu. If there are more devices then the software is most likely in demo mode. When the ALP is operating in demo mode there is a (Demo Mode) indication in the lower left of the application status bar as shown below.

Disable the demo mode by selecting the Preferences drop-down menu and unchecking Enable Demo Mode.

After demo mode is disabled, the ALP software will poll the ALP hardware. The ALP software will update and have only DS90UB95x under the Devices drop-down menu.
