I am finding a problem to align the Logitech Performance Mouse MX with the Unifying Receiver. I am using Windows 7 (64bit) and when I tried to install the driver, it replied “USB Receiver: No driver found”. W7 cannot find the driver anywhere. Logitech says it is not their fault. It is using W7 native USB driver, so there is no driver that I can download and install to fix it. W7/64bit even shows the unifying receiver icon in the Devices. But W7 tags it as not working because it canât find the driver. Can anyone suggest me the solution?
