Running UUU on Windows 7¶
From the NXP UUU Windows 7 User-Guide
Windows 7 ships with correct ‘winusb.sys’ file, but is missing an updated ‘.inf’ that associates with “usbms_comp_winusb” devices. Normally if the USB device supports Microsoft OS descriptors, then it will allow Windows to automatically install the WinUSB driver. This mechanism is supported “in-box” for Win8 and newer. For Windows 7 the mechanism is supported through Windows update. Depending on the update policy for the Windows 7 machine, the appropriate driver may or may not be already available on the machine. If it is not already on the machine, user can use the following manual procedure to install the driver if necessary.

Using Zadig to make UTP work¶
