5. General USB troubleshooting in Windows 98
Second Edition and Windows ME.
The information in this article applies to :
*Microsoft Windows Millennium Edition
*Microsoft Windows 98 Second Edition
Because USB device are plug and play devices, there is little that you
can do to control or configure them. However, you can trace most USB
problems to one of the following conditions :
*Malfunctioning or incorrectly configured hardware
*Malfunctioning, incorrectly configured, or missing device driver
*Out-of-date firmware or basic input/output system (BIOS)
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.

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
There are two types of USB cables, high speed and low speed. Low-
speed cables differ from high-speed cable 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 than 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
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 malfunction 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 a 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. 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.
6. Adjusting the Speaker Volume and Microphone
Levels.
Test that the speaker volume in your headset is working and set at a
comfortable level by adjusting the RX volume buttons(Volume up for +, Volume
down for -).
The audio tab in the Properties window also lets you adjust the Sound
Recording or microphone levels. The Volume slider adjusts the sound recording
or microphone levels. Make sure that the volume slider is set in the middle of
the control and the Mute box is not checked.
* Theses controls adjust the volume, however, many other applications contain
their own volume controls. These independent applications may override the
Windows controls and work independent of the USBAdapter sound controls.
