Microsoft USB Mass Storage Device Free Driver Download for Windows 2003, XP, 2000, NT4, NT3.51, ME, 98SE, 98, 95, 3.1. World's most popular driver download site.

Multiboot system: Win7 w/SP1, Win10 Build 14393.10 (upgraded 8.1), and Win10 Insider Preview Build 14393.10; all 64bit.

One major problem is that in Win10 Build 14393.10 (upgraded 8.1) no flash drive is recognized. This happens if I plug-in the device and boot or boot then plug-in the device. Booting with the device plugged-in: Device Manager > Universal Serial Bus Controllers > USB Mass Storage Device has a yellow triangle with an exclamation point included > PropertiesGeneral: This device cannot start. (Code 10) - STATUS_DEVICE_NOT_CONNECTED. The Safely Remove Hardware and Eject Media icon in the taskbar when right-clicked does not list the flash drive. If I remove the drive I do hear the 'disconnected device' sound and the item disappears from Device Manager. Plugging the drive back in reverses the process.

I can move this drive to another USB port - same problem. I can try different flash drive - same problem. I can reboot to either of the other operating systems and the drive is recognized using either method.

Uninstalling the device from Device Manager and rebooting has no effect - problem still exists.

Booting to Win7 or Insider Preview - the flash drive appears as expected; as do other flash drive plugged into various other USB ports.
