Can I use U22 XT under Windows XP?
No, not fully. U22 XT
is using a newer version of our driver engine that only supports Windows Vista
and later versions of Windows. Because of that, it cannot be used under Windows
XP. U22 XT will be available for use under Windows XP if you do not install
our driver, with limited functionality. We strongly recommend to use Windows
7 or higher.
