It should make error connecting sound and you would not see the Storage device. Put computer to sleep, wake the computer and try USB Mass storage device again.

I have no problems on an Acer Laptop with 64-bit Windows 8 and Intel USB 2.0 controller, so it must be something with Renesas USB 3.0 controller or drivers and Forticlient on Lenovo 420s.Д¬an anyone confirm the issue on other (probably USB 3.0) laptops or desktops that go to sleep? Just install Forticlient, restart, plug in USB Mass storage device (no mice or keyboards) - it will work. If I uninstall Forticlient, everything works fine. Restarting a laptop fixes the issue, until next sleep. I could check the Renesas controller driver though (not sure which one is installed and I am away from Lenovo laptops). Laptops were upgraded to latest Lenovo drivers, and BIOS was flashed too. This laptop model has Renesas USB 3.0 controller, and USB Mass Storage Device has the default Microsoft driver.

I could provide additional info if you need it for analysis (didn' t check System events for errors yet). Windows driver properties says that it cannot load driver since one is already loaded in memory. Lenovo 420s laptops with 32-bit Win 7 Enterprise have a Mass storage device not working in Device manager after laptop wakes from sleep and the newest Forticlient is installed.

On some computers USB memory stick or any Mass storage device (like cameras) don' t work after Forticlient is installed and computer wakes from sleep.
