Windows XP USB 2.0 driver patch

In Windows XP version before SP2, Microsoft did not provide compatible USB 2.0 driver 
to this PC Camera driver.
Most M/Bs include third-party drivers but some drivers' version are not compatible to
this PC Camera driver.  However, Windows XP SP2 and later do provide compatible
USB 2.0 driver by default.

This "usbehci.sys" file is for replacing the third party USB 2.0 driver 
which is installed into "%windir%\system32\drivers\usbehci.sys".

One can replace "%windir%\system32\drivers\usbehci.sys" with this included "usbehci.sys"
in order to get this PC Camera driver to work in older version of Windows XP which is 
before SP2.

It is suggested to use installer program to install this USB 2.0 driver file patch.
