Original Equipment Manufacturer (OEM) Version Identification
Windows 95 may have been preinstalled on your computer. These installations are referred to as OEM installations. An OEM Service Release (for example, OSR2) is an updated version of a product for PC manufacturers (OEMs) to preinstall on new PCs. The purpose is to allow OEMs to install an integrated Windows 95 product that contains the latest available individual updates and supports recent advances in hardware that require core operating system support.
Additional OEM Information
- In Windows 95 OEM Service
Release 2 (OSR2), 2.1 (OSR2.1) and 2.5 (OSR2.5), not all files have
the version stamp that is listed in the table. In OSR2.1 and OSR2.5,
only files that were updated to provide support for the Win32 Driver
Model (WDM) and USB may have this version stamp (the other files have
the same version stamps as the corresponding OSR2 files).
You can view file version information by right-clicking a file in Windows Explorer, clicking Properties on the menu that appears, and then clicking the Version tab. If there is no Version tab, there is no version information available for that file. - Updates to Windows 95 OEM OSR2 generally have a version of 4.00.1112 or later.
- To determine whether you are running OSR2.1, check for "USB Supplement to OSR2" in the list of installed programs in the Add/Remove Programs tool in Control Panel, and check for version 4.03.1212 of the Ntkern.vxd file in the Windows\System\Vmm32 folder.
- If you are running OSR2.5 and you uninstall the USB Supplement by using the Add/Remove Programs tool in Control Panel, the version number changes to 4.00.950b on the General tab in System properties.
NOTE : All versions of Microsoft Windows 98 include USB support.

BIO's & USB
(from experience)
Some older Motherboard's have the USB port disabled by default. To enable the USB port you have to reboot your PC & whilst it is counting memory press the key that allows you to enter setup ( this varies alot between manufactures)
Search through the various pages looking to the setting that refers to USB Port and ensure that it is has been enabled.
Save the new settings > Exit > Reboot

SUMMARY
This article describes general troubleshooting tips for Universal Serial Bus (USB) devices in Windows 98, Windows 98 Second Edition, and Windows Millennium Edition (Me).
MORE INFORMATION
Because USB devices are Plug and Play devices, there is little that you can do to control or configure them. However, most you can trace most USB problems to one of the following conditions:
- Malfunctioning or incorrectly configured hardware
- Malfunctioning, incorrectly configured, or missing device driver
- Mismatched cabling
- Out-of-date firmware or basic input/output system (BIOS)
- Improperly configured root hub
You can use the following troubleshooting tips to check for each of these conditions to help you resolve USB device issues.
Malfunctioning or Incorrectly Configured Hardware
Typically, if you plug a malfunctioning or incorrectly-configured
device into a USB port, it causes the computer to stop responding (hang).
In the majority of these instances, you must physically turn off the computer
and turn it back on to reset the bus. Note that it may be more difficult
to identify which device is malfunctioning or is incorrectly configured.
If another computer that you know is working correctly is available, try
to plug the device into that computer to see if you encounter the same
issue.
If the device is plugged into a secondary hub, unplug the device from
the hub and then plug the device directly into the root hub.
Many hardware problems (such as high or low power, bandwidth shortage,
malfunctioning or incorrectly configured firmware, and so on) can cause
issues to occur.
Check Device Manager to be certain that the root hub is functioning correctly.
If the root hub is displayed with an exclamation point in a yellow circle,
verify that the BIOS is assigning an interrupt request (IRQ) to the root
USB controller. This is required for the device driver to be loaded. For
additional information about how to use Device Manager to troubleshoot
hardware issues, click the article number below to view the article in
the Microsoft Knowledge Base:
Q133240 Troubleshooting Device Conflicts with Device Manager
If no devices work when you plug the devices into the root hub,
verify that the power requirements of the bus are not being exceeded.
USB devices can draw a maximum of 500 milliamps for each connection. If
a device attempts to draw more power than this, the specification recommends
that the computer be able to disable that specific port until the computer
power is cycled (this is called "suspending" the port). In addition,
if the device draws less than 50 milliamps, the port never becomes active.
Check the Power tab in USB Root Hub properties to check the power
usage of the USB bus.
Malfunctioning, Incorrectly Configured, or Missing Device Driver
When you plug in a USB device, the computer should load and then configure the device without ever requesting a device driver (assuming that the device falls within the defined and supplied class drivers). If the computer prompts you for a device driver, check with the manufacturer of the device to determine if a driver is available.
Mismatched Cabling - (unlikely with Vpedal but....)
There are two types of USB cables, high speed and low speed.
Low-speed cables differ from high-speed cables primarily in their shielding.
If you plug a high-speed device into a low-speed cable, you can cause
signal distortion over long distances.
Verify the entire USB chain is working correctly to be certain that a
device that requires the ability to draw power from the hub is not plugged
into the chain on the other side of a non-powered hub. This causes that
hub and all of the devices down the chain to be suspended. If the hub
is a powered hub, verify that the power supply for that hub is configured
properly.
Out-of-Date Firmware or BIOS
( You may have to update your Motherboards BIO's)
The key to all USB devices is the firmware. The USB device's
firmware contains all of the information about the device. A port is not
reset until all of the descriptors in the firmware have been loaded and
verified by the root hub. This is critical because it applies to items
such as printers and modems. Make certain that you have the most up-to-date
firmware that is available for both your computer's BIOS and each individual
device.
The symptoms of malfunctioning or incorrectly configured firmware might
be unusual. Typically, when you remove and then re-add a USB device, the
device simply becomes available again. However, the device may appear
as a second instance of that device, and load itself as such in Device
Manager. If you see duplicates of a device, verify that you have the most
up-to-date firmware for that device. This issue is common with USB printers
and modems. A similar issue that has the same cause occurs when a device
loads a device driver and then adds a second device for which there appears
to be no driver. The second device is displayed with an exclamation point
in a yellow circle in Device Manager. The device may work correctly, but
you cannot remove the "ghost" device until you unplug the parent
device that seems to have generated the ghost device. Also, you may be
able to resolve this issue by updating the firmware or the device driver
for that device.
Incorrectly Configured Root Hub
USB controllers require that an IRQ be assigned. The IRQ line is assigned in the computer's BIOS, and usually IRQ 9 is a
