version or service pack.
2.
A USB peripheral is detected by the computer but not functioning properly.
SOLUTION:
Click the right mouse button on the My Computer icon and select Properties. Select
Device Manager and view the Universal Serial Bus Controllers. One of the following four
conditions are displayed:
(a) If the peripheral is displayed in the Device Manager, the USB 2.0 PCMCIA Adapter is
working properly. The problem exists with either the peripheral or its software drivers. Try
disconnecting the USB device, closing any software that may be trying to access the
peripheral, uninstalling the USB peripheral software drivers, reboot the computer, and
then reinstall the software drivers. Connect the USB peripheral to the computer after the
software drivers are installed. Refer to the manual for the USB peripheral for more
information.
(b) If the device displays as an unknown device, check the following items:
i. If the USB device is connected to a USB port of a USB Hub, unplug it from the USB
Hub and plug it directly into a USB port on the notebook or the USB 2.0 PCMCIA
Adapter.
ii. The device may not be getting enough power. If multiple USB peripherals are in use,
remove them all (except keyboard and mouse) and restart the computer. Upon
restarting Windows, check the Device Manager again. If this solves the issue, use a
self-powered USB hub to provide power to the USB peripherals.
iii. Disconnect the USB peripheral, close any software that may be trying to access the
peripheral, uninstall the USB peripheral software drivers, reboot the computer, and
then reinstall the software drivers. Connect the USB peripheral to the computer after
the software drivers are installed.
(c) If the peripheral is displayed under Other Devices in the Device Manager, the USB
ports are working but the device software drivers need to be installed. Unplug the USB
device and install the software drivers.
(d) The device is not listed in the Device Manager anywhere. Read the following section
for troubleshooting this scenario.
