[quote]1. The instruction specification of folder “PCSGU250Driver_WinUSB” I believe should read “PCSGU250_WINUSBDRV2”[/quote]Indeed there seems to be an old picture with old path name for the WinUSB driver in the installation manual. You are right - should be instead pcsgu250_winusbdrv2.
[quote]2. My old driver was 1.0.0.6 19/12/2007 where as my new driver is 1.0.0.2 24/08/2009
How and why 1.0.0.6 was created before 1.0.0.2 is a bit confusing.[/quote]Indeed the driver version numbering can be confusing.
There on the installation CD are two different drivers for the PCSGU250.
One in the folder PCSGU250Driver.

The vendor of this driver is Microchip.
This is the only working driver for Windows 2000.
This driver can be used with Windows XP too.
The second driver is in the folder PCSGU250Driver_WinUSB.
This is WinUSB driver version 1.0.0.0 dated 21/05/2008.
The vendor of this driver is Microsoft.
This driver can be used with Windows XP, Vista and Windows 7 and 8.
The latest version of the WinUSB driver 1.0.0.2 dated 24/08/2009 can be downloaded from the Velleman web site.
