Yes I agree Windows XP64 and Windows 2003 are out of our
concerns since they are not supported by Microsoft.

On the other hand, it is interesting to see that WinUSB actually works
under XP64.

Even Microsoft webpage contains information for 64bit Windows
XP WinUSB support.

For all supported x86-based versions of Windows XP
File name	File version	File size	Date	Time

For all supported x64-based versions of Windows XP

This pages says Windows 2003 are not supported but all SKUs
of XP SP2/SP3 are supported. But not so sure if XP 64bit is
considered as an XP SKU or not. I remember some older page
mentioned only XP SP2/SP3 32bit SKUs are supported but I
did not see 32bit mentioned in the notes.

It seems to me maybe XP 64bit WinUSB is supported after all.

I forgot this one myself.
