Where can I find the Windows driver for KeyControl 25/49/61 XT?
KeyControl 25 XT,
KeyControl 49 XT
and KeyControl 61
XT do not not require any special driver for Windows XP, Windows Vista,
Windows 7, Windows 8/8.1 und Windows 10.
The keyboards are so-called "Class Compliant" products
which means that they work with the default drivers that are included in Windows.
To use them, simply connect the unit with the USB port of your PC and you can
start using it in your applications.
