Assuming the correct Windows 7 chipset actually was installed (the status indicates failed - but other blog postings suggest that the chipset was in fact installed/ maybe) - the problem is with usb port deactivation by automatic driver install function running (I think). What happens is that I proceed with un-installing the usb drivers (using the device manager) and then restart the computer (with for example the mouse and keyboard plugged into the usb ports) - I get temporary use of my mouse and key board - until the automatic driver install function launches. I have attempted to block this via two methods (i.e. in device manager hardware installation settings and in the windows update settings) but neither method stops the inevitable automatic attempted search and update of drivers (by the automatic driver install function) - that fails to find drivers and subsequently results some how in deactivation the usb ports/ devices. The only thing visible in the device manager (after the usb deactivation) are two intel chipset drivers, and under the other devices - there are two (apparently) parallel "unknown devices" that subsequently disappear if I again uninstall the two intel chipsets - then restart repeats the cycle of usb/mouse/keyboard devices working temporarily (1-2 minutes) until the automatic driver install function deactivates the usb ports/ devices.
The problem I believe started a while ago when I had an automatic windows update that appears to have inactivated usb ports to any new usb devices - when I (recently) tried to fix the problem by un-installing usb drivers/ downloading the latest intel chipset utility and rebooting computer - the problem expanded - so now no usb devices work (for any significant period of time). I would very much appreciate any suggestions for fixing the usb deactivation problem in a windows 7 OS. Thanks.
