My computers usb ports not working properly. I am using usb mouse from logitech. This usb mouse works perfectly on other laptop.
problem is like this..
those usb host controllers does not work properly sometimes, sometimes works fine.
Now usb mouse working fine but after shutting down, or after 2-3 hours or any time usb mouse stops working.
When usb mouse stops working I always check device manager, and those highlighted usb controllers in image below shows icon with yellow triangle with exclamation mark.

I manually update driver using keyboard as mouse. Then after every successful installation of usb host driver, device manager page automatically refreshes and usb host controllers again shows yellow triangle with exclamation mark. After doing it again and again, if it gets stable then I update all drivers manually. If not then I turn of computer for few hours and try again.
(I changed setting for "Device Installation Setting" as "No. Never install driver from windows update" in "Control Panel\Hardware and Sound\Devices and Printers")
But mouse does not work after this. When I uninstalled USB2 Enhanced Host controller, then usb mouse starts working.
Another problem is this, after uninstalling this USB2 enhanced host controller, flash/pen drive transfer at speed of 1 mbps not 16 mbps reglular speed. But if I re-install this USB2 enhanced host controller, then usb mouse does not work.

Need help.

solved by myself..
In device manager I manually corrected driver under "Human Interface devices", from something I don't remember now to "USB input device".. it solved my all problem and every usb port works fine now.
