This identifies what each of your USB's is doing and what device is attached. The usual course of action is to go onto control panel/hardware and sound/device manager and delete all usb keys then reboot and allow windows to rediscover them.Ī less draconian solution that worked for me is to map your USBs using a microsoft utility called usbview downloadable from Future Technology After manually installing the Windows 7 USB 3.0 drivers I was able to use the Voyager GT at USB 3.0 speeds again. I was unable to use the Voyager GT at all. I had the same USB 3.0 (Fresco brand) problems with my Corsair Flash Voyager GT 64GB with the Microsoft Windows 8 driver. I'm starting to suspect either a driver bug or a controller erratum that wasn't handled by Microsoft's driver.Ĭan you try to isolate the controller that's generating these hardware events? You can use the "View devices by connection" in device manager to see what's actually enumerating that unknown device. I've confirmed that this issue affects 2 different machines which are both running Windows 8 and use Intel's 7-series chipsets for USB 3.0. Both the ASMedia and the Intel controllers are using the same Microsoft driver but they behave very differently when I log the driver behavior using WPP tracing of the USB stack core components. I see that you're running Windows 8 and the issue I'm debugging appears to be an incompatibility with Microsoft's USB 3 driver (which started shipping in Win8) and Intel's USB 3 controller. It works fine on my ASMedia USB 3.0 controller, but fails to enumerate (with the same unrecognized device message) when connected to the Intel USB 3.0 controller. I'm actually currently debugging a curious issue that seems to affect Intel USB 3.0 controllers when using my Corsair Flash Voyager GT (possibly other devices too).
This could be caused by driver issues, controller bugs, or device problems. Keep me posted on further assistance.It's probably a USB device that failed enumeration.

Try using a different USB and check if the issue persists, this could be an issue with the printer. To provide you with an accurate solution, I'll need a few more details:
