If you connected the DEMOQE128 interface prior to installing P&E’ s
Embedded Multilink drivers, Windows will not have been able to find the
appropriate driver and may have disabled the device. The DEMOQE128
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 DEMOQE128 interface is connected to the computer:
(B) Re-Install the USB driver
If the Multilink device does not show up in the device manager, use the driver
installation utility located in the DEMOQE Resouces on the DVD-ROM. After
driver installation, unplug the DEMOQE128 from the PC and reboot the PC.
When the reboot has completed, connect the interface to the PC with the USB
2.0 cable. Run the software again to see if the interface is now detected.
If you have an error attempting to install the drivers, please view the
installation troubleshooting FAQ on P&E’ s website at:
http://www.pemicro.com/faqs/faq_view.cfm?id=89.
(C) Test for installation of the USB driver files
To test the driver installation, use the driver test utility in the DEMOQE
Resources of the DVD-ROM to make sure all files were properly installed.
This may give some indication of what the problem is.
(D) Using a USB Hub
The DEMOQE128 is a high-power USB device. If a USB Hub is used, it must
be a self-powered hub (i.e., with its own power supply). If the Hub is not self-
powered the DEMOQE128 will not work. In general, USB ports located
directly on the PC are high-power (self-powered) ports.
