USB MIDI keyboard - there are 4 drivers found for the selected device, which you can download from our website for free. The only way to avoid the warning is to pay Microsoft for WHQL (like the driver package in C:\Microchip Solutions\USB Tools\MCHPUSB Custom Driver\MCHPUSB Driver).

So you just need to use the inf-wizard to generate a new driver package for your device.Īctually the inf-wizard in 1.2.1.0 can be even used to automatically install the driver. The original driver package can not be used under 64bit Windows Vista and Windows 7 without some hack (enable test signing or disable signing check) which are not really meant for end users.Īs m_gray mentioned, you should use the latest version of libusb-win32 (now it is 1.2.1.0), libusb-win32 kernel driver (libusb0.sys) is digital signed and can be installed under 64bit Windows Vista and Windows 7.
