2) Click once on the Device Manager tab to view a listing of installed hardware devices.
3) In the Device Manager tab, your hardware devices are in alphabetical order and
should include a Universal serial bus controller toward the bottom of the list. Double
click on this device to open it.
In order for the Edgeport and other USB devices to work properly, at least two devices
are required and will be listed. Although the exact name of each manufacturer’s device
listing can vary, the names of these two required USB devices should include the follow-
ing descriptive words:
• USB Root Hub
• USB Host Controller
The above is an example of what you might see listed under the Universal serial bus con-
troller. If you do not see one or both of these devices, go to “Determining Why Support Is
Not Present” in the next section.
Determining Why Support Is Not Present*
The DETAILS button in USBREADY can help you determine what is preventing USB sup-
port.
1) Click on the DETAILS button.
If the USB Class Host Controller window reads, “
No USB Host Controller Found
” then
the necessary hardware, a USB Host Controller, has not been detected. If your PC does
not have USB connectors, then this system will not support USB regardless of the Win-
dows version. You will need to purchase a PCI USB controller card, such as the Step-Up
card from Inside Out Networks. If your PC does have USB connectors, verify that the
USB hardware is enabled in your system BIOS configuration.
If the USB Class Host Controller window displays any other message, such as
“
Standard
,” “
Intel
,” “
Universal
,” or “
Open
” Host Controller, then hardware support is pre-
sent, but an incompatible version of Windows is currently installed.
If the Test Results Details dialog shows Windows 95 version 4.0.1111, which is Windows
95 OSR.2, proceed to “Installing Microsoft USB Support” on this page. You will need to
upgrade to OSR 2.1 by installing the USB supplement before installing the Edgeport.
Installing Microsoft USB Support
Microsoft provides a supplemental program (usbsupp.exe) to allow users to upgrade Win-
dows 95 version OSR2 to support the Universal Serial Bus. In order to install this support
perform the following steps:
1) Insert your Windows 95 CD into your CD ROM drive.
2) In the START menu, select RUN.
3) Type
<CD drive letter>:\other\usb\usbsupp
.
Follow the instructions on the screen. After rebooting, return to the Windows 95 installa-
tion instructions for your particular Edgeport product. Ensure that the Test Results Details
(from the Details button in the USB System Checker dialog) displays Windows 95 version
4.1212 or higher.
*Note that Windows 95 versions 4.0.950 and 4.0.950a do not support the upgrade path to USB. Unfortunately, Microsoft
has not provided an upgrade path to OSR2 from earlier versions of Windows. OSR2 must be preinstalled by your PC
vendor. Contact your PC vendor for more information.
