Figure 11 shows an error that pops up if the computer cannot communicate with the EVM. If you receive

this error, first check to see that the USB cable is properly connected. This error can also occur if you

connect the USB cable before the USB DIG Platform 9V power source. A second possible reason for this

problem is that there may be a problem with your computer USB Human Interface Device Driver. Make

sure that when you plug the in the USB cable, the computer recognizes the device. If the sound is on, you

will hear the distinctive sound that you expect when a USB device is properly connected to the PC.
