I just received the USB 3.0 I/O card, model: PCIE-USB3-SP. Installed card into a Dell Studio XPS running Windows 7 Pro x64. Booted the PC and ran "setup.exe from the included mini disk and also rebooted after the installation of the NEC driver. Two windows came up after I logged into Windows 7. The first said the device driver failed to load and then another window stated that “Windows requires a digitally signed driver” It goes on to say that “A recently installed program tried to install an unsigned driver. This version of Windows requires all drivers to have a valid digital signature. The driver is unable and the program that uses this driver might not work correctly…Uninstall the program or device that uses this driver and check publisher’s support website to get a digitally signed driver.” Below all of this states the following: DRIVER: USB 3.0 Host Controller Driver; SERVICE: Renesas Electronics USB 3.0 Host Controller Driver; PUBLISHER: Renesas Electronics Corporation; LOCATION: C:\Windows\System…\nusb3xhc.sys
I uninstalled the driver and shut down. I swapped PCIe slots with my video card and booted again. Installed the driver once again and received the same error messages. I found that there is a newer driver online so I downloaded it and installed it after removing the original driver, rebooted and received the same error message.
Suggestions?
