I have a problem with usb drivers on Windows 7 64bit
When I start up my laptop, the mouse I have plugged into a usb port does not work. I have to open the device manager, where there are two "Standard Enhanced PCI to USB Host Controller" entries. One is marked as faulty (yellow triangle). I uninstall this. Scan for changes. Then it re-appears, but not marked as faulty. And the mouse works.
I have to do this every time I reboot. A colleague has the same problem. Both DELL laptops, but different models.
I've tried uninstalling all USB controllers, but after a reboot, they are all reinstalled with the faulty entry.
This only started happening in the last few weeks.
Any help appreciated. It's driving me nuts.
