DEMOEM User Manual
If the Multilink device does not show up in the device manager, use the driver
installation utility located in the DEMOEM Resources on the DVD-ROM. After
driver installation, unplug the DEMOEM 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 DEMOEM
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 DEMOEM 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 DEMOEM will not work. In general, USB ports located directly on
the PC are high-power (self-powered) ports.
