I have a Platform Cable USB model DLC9G (or DLC9LP), but I cannot connect to it using Xilinx design tool versions 8.1i sp3 or earlier. What do I need to do?
The drivers for DLC9G and DLC9LP were not delivered on the software installation CD/DVDs until software version 9.1i. If using a version earlier than 9.1i, you must either upgrade to the latest version of the design tool (recommended) or manually install the cable driver. For complete details on obtaining and installing USB cable drivers, see the USB Cable Installation Guide (UG344): http://www.xilinx.com/support/documentation/configuration_hardware.htm.
