Installation
1 Check for USB Driver Files. Files are listed in their default directories
for Windows 2000 and Windows 98 (SE)/Me/XP. Verify that the driver
files are installed. If they are installed, go to Check IO Control
Operation. If not, go to substep 2 following.
NOTE
USB ports ONLY operate properly on Windows XP when the latest
Microsoft USB drivers from Windows XP Service Pack 1 have been
properly installed. However, upgrading your XP PC to SP1 will probably
not automatically update the USB drivers. See
www.agilent.com/find/
connectivity
to verify if correct USB drivers are installed and to install
correct drivers as required.
