**Obsolete** 3.3i ChipScope - "Failed to open communications port" error when using a USB port and MultiLINX cable on Windows 98 SE


Keywords: ChipScope, port, USB, MultiLINX, Windows 98, Win98, SE, fail

Urgency: Standard

General Description:
In ChipScope, the following error appears when I go to the Communications menu and choose USB -> MultiLINX Cable.

"Failed to open communications port."

(This occurs when a MultiLINX cable is used through the USB port on a Windows 98 machine.)


Make sure the MultiLINX USB driver has been installed correctly.

For more information on this, please see pages 1-11 (15 of 79) of the ChipScope User's Manual: "Installing the MultiLINX USB Driver for Windows 98."
