USB DIRECTORS RS-232

5.Troubleshooting

5.1Using USB with Windows 95

If you’re having difficulty installing or operating your USB Director RS-232 in a Windows 95 system, check the revision level of your copy of Windows 95. If you are using Windows 95 OSR2.1 or above, take the steps described in Sections 5.1.1 through 5.1.4. If not, you will need to upgrade to a more recent version of Windows.

5.1.1CHECKING FOR USB HARDWARE

To verify that the necessary USB host controller is installed in your system, make sure that your PC has USB connectors. If it doesn’t, your PC will not support USB regardless of which Windows version it’s running. You will need to purchase a PCI USB controller card.

If your PC has USB connectors, verify that the USB hardware is enabled in your system BIOS configuration. In some cases your manufacturer may have elected to ship your PC without the USB-support drivers installed. If the two USB-hardware listings that should be there (“root hub” and “host controller”—see Section 5.1.3) are absent in your Device Manager, you will need to upgrade to a more recent version of Windows.
