 You usually need to have WinUSB.sys (or libusbK.sys) driver installed
 for a USB-based adapter. Some vendor software (e.g. for ST-LINKv2)
 does it on its own. For the other cases the easiest way to assign
-WinUSB to a device is to use the Zadig installer:
+WinUSB to a device is to use the latest Zadig installer:

 For the old drivers that use libusb-0.1 API you might need to link
 against libusb-win32 headers and install the corresponding driver with
 Zadig.

+If you need to use the same adapter with other applications that may
+require another driver, a solution for Windows Vista and above is to
+activate the IgnoreHWSerNum registry setting for the USB device.
+
+That setting forces Windows to associate the driver per port instead of
+per serial number, the same behaviour as when the device does not contain
+a serial number. So different drivers can be installed for the adapter on
+different ports and you just need to plug the adapter into the correct
+port depending on which application to use.
