I have bought a Logitech M510 which uses an unify receiver. Windows doesn't install the needed driver. (No drivers have been found) I tried it on different USB ports. I tested the unify receiver on another computer. It works there. I also contacted the Logitech support. They said it is an issue with the windows standard HID driver. They recommended to update the BIOS and to update the USB driver.
