Q: The connection assistant indicates that my DEMOEM is undetected even 
though I have connected the hardware to my USB port. What should I do? 

A: The connection assistant, which displays in either Codewarrior or P&E’s 
development software, is a dialog which allows the user to connect to the 
DEMOEM hardware. If this dialog indicates that the DEMOEM hardware is 
not connected to the PC, the first step is to make sure that the DEMOEM 
hardware is connected to the PC via a USB 2.0 high-speed cable. If it is 
connected, unplug and then plug in the USB cable on the DEMOEM board 
and click refresh in the connection assistant. If the hardware still does not 
show up, try the following remedies: 

If you connected the DEMOEM interface prior to the installation of P&E’s 
Embedded Multilink drivers, Windows will not have been able to find the 
appropriate driver and may have disabled the device. The DEMOEM board 
shows up in Window’s device manager as a “P&E Multilink,” since it contains 
P&E’s Embedded Multilink circuitry. If you unplug and then plug in the device, 
Windows will automatically disable it even if you have installed the drivers. To 
force windows to try to load the driver again, perform the following steps while 
the DEMOEM interface is connected to the computer: 

1.

Open the Control Panel (Start Button->Settings->Control Panel) 

2.

Double Click the "System" Icon 

3.

Select the "Hardware" tab 

4.

Click the "Device Manager" Button 

5.

The "P&E Multilink" device will be shown with an exclamation mark 
next to it. Double-click this device. 

6.

Click the "Reinstall Driver…" button and follow the dialog instructions 
to have Windows automatically install the driver.
