1.3.2. Installing the USB driver
(1) When the system is connected with the VG for the first time, it recognizes the VG, and the [Add New Hardware
Wizard] dialog box appears. Select the [Next] button.
(2) Select [Search for optimal driver for device in use (recommended)] as the search method, and select the
[Next] button.
(3) Place the SP-8848 installation CD in the CD drive, check [Specify search location], specify CD drive
and select the [Next] button.
(4) Check that "VgUsb.sys" has been found, and then select the [Next] button. Installation now begins.
(5) For the remaining steps, follow the on-screen directions.
*When installing the driver in Windows XP, the following dialog box appears referring to the fact that Microsoft
has not officially certified its use. Press the [Continue] button.
1.3.3. Uninstallation method
In Windows, select [Start]
→
[Settings]
→
[Control Panel]
→
[Add/Remove Programs], and delete the software by
following the on-screen directions.
During this process, the user will be asked whether to delete "VGPIO.vxd" which has been installed in the Windows
system directory. Leave it if it is required. However, if the software is to be re-installed, the files and registry settings
must be deleted by uninstalling them before proceeding. The data files in the VGInt directory and UserChar directory
are read-only files and, as such, they are not deleted by uninstallation. Delete them separately. Similarly, if the USB
driver has been installed, it will not be deleted by uninstallation either, so delete it separately.
