<title>USB Tablet Coordinates Wrong in Windows 98 Guests</title>
<body>
<p>
If a Windows 98 VM is configured to use the emulated USB tablet
(absolute pointing device), the coordinate translation may be
incorrect and the pointer is restricted to the upper left
quarter of the guest's screen.
</p>
<p>
The USB HID (Human Interface Device) drivers in Windows 98 are
very old and do not handle tablets in the same way as modern
operating systems do. To work around the problem, use the
following command:
</p>
<pre xml:space="preserve">$ VBoxManage setextradata <varname>VM-name</varname> "VBoxInternal/USB/HidMouse/0/Config/CoordShift" 0</pre>
<p>
To restore the default behavior, remove the key or set its value
to 1.
