I have the similar problem.
My flash drive did connect and functionnal on my laptop ASUS.
Suddenly it is not recognized anymore by Windows, it is not displayed in the Computer window Explorer.
At the beginning, the flash drive was getting work after the reboot. But not now.
The flash drive is VERBATIM 1TB.
My OS :
- Windows 7 Professionel 64 bits, SP 1
- I applied Windows Updates regularly. Last updates installed on 6-Aug-2013.
I did the following check :
- Connect the flash drive to other PC & LAPTOP. The flash drive is recognized and functionnal.
- For the laptop ASUS :
. Connect to other USB port. --> not work.
. In the Event Viewer :
. Check error in Applications/Microsoft/Windows/DriverFrameWorks-UserMode/Operational
--> oNLY 1 event and the message is "The Driver Manager service started successfully".
. Check error in Windows Logs/Application
--> 1 warning "LMS Service cannot connect to Inter(R) MEI driver
. Check USB Storage Device - Enable in Windows registry
. In HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\USBSTOR , Start value is 3.
