This document describes the installation procedure of the IR550A USB driversunder Windows XP and gives information on what to look for if installation doesn't go as planned. The driver installation is a two stage process, firstly the USB section of the driver is loaded followed by the COM Port driver.
The CD-ROM provided should be inserted into the CD-ROM drive of the PC prior to plugging in the device. Plug in your device. This should bring up a "Found New Hardware" help bubble and launch the Found New Hardware Wizard. These should describe the Hardware as "IR550A USB version".
Make certain that the "Install the software automatically" option is checked. Click on "Next" to continue.
You may see the above screen during the installation process as Windows XP copies the files from the CD. No user intervention is required.
The drivers do not have a Microsoft WHQL certificate on the disk. ERSA frequently updates it's drivers in response to customer requirements and each update would require a new certificate which would slow down our ability to release new updates. Our drivers have been tested in-house using the Microsoft WHQL test suite and are safe to install in Windows XP. The default button is "STOP Installation" - ignore this and click on the "Continue Anyway" button.
The USB Drivers have now been installed - click the "Finish" button finish the USB driver installation and to install the COM Port drivers. The Found New Hardware wizard will re-launch for the second part of the driver installation as shown below.
