Now you are prepared to start the driver installation. The required steps
are described below.
• Connect your USB device to the system. After plugging in the
device Windows launches the New Hardware Wizard and prompts
you for a device driver. Provide the New Hardware Wizard with the
location of your installation files (usbio.inf and usbio.sys).
Complete the wizard by following the instructions shown on
screen. If the INF file matches with your device the driver should
be installed successfully.
Note that on Windows 2000 and Windows Millennium the New
Hardware Wizard shows a warning message that complains about
the fact that the driver is not certified and digitally signed. You may
ignore this warning and continue with driver installation. The
USBIO driver is not certified because it is not an end-user product.
When the USBIO driver is integrated into such a product it is
possible to get a certification and a digital signature from the
Windows Hardware Quality Labs (WHQL).
• If the device belongs to a predefined device class that is supported
by the operating system, the system does not launch the New
Hardware Wizard after the device is plugged in. Instead of that a
system-provided device driver will be installed silently. Human
Interface Devices (HID) like mice and keyboards, Audio Devices,
or Printer Devices are examples for such devices. The operating
system does not ask for a driver because it finds a matching entry
for the device's class and subclass ID in its internal INF file data
base, as mentioned above.
Use the Device Manager to install the USBIO driver for a device
for that a driver is already running. To start the Device Manager
choose Properties on the "My Computer" icon on the desktop. In
the Device Manager locate your device and choose Properties on
the entry. On the property page that pops up choose Driver and
click the button labeled "Update Driver". The Upgrade Device
Driver Wizard is started which is similar to the New Hardware
Wizard mentioned above. Provide the wizard with the location of
your installation files (usbio.inf and usbio.sys) and complete the
driver installation by following the instructions shown on screen.
