I am not going to tell my problem or trouble but rather to tell what I had done based on what I found out from other responses to "related issues" subjected above. I just thought that I must do this for the sake of others, brothers and sisters in Jesus Christ.
I wanted to go back to the threads that I have found helpful to post this but I am not that fond of using the search fields and somehow my google search results on this lappy is quite differ from the one i got on the usb-troubled lappy that i used to log into sevenforums. i have read through just about 10 of the related result on sevenforums but not one of them is the one i found out earlier.
anyways, what i did was: uninstalled all usb listings in device manager and then just shut down the lappy, unplug all cables including power cable and went out for a smoke. a few minutes later, came back and plugged the power cord and turned on the lappy. and somehow, windows auto-install everything and since the lappy is wirelessly connected to the internet like always, it also download and install everything. then i plug the main cause of the problem (microsoft 5-button intelligent mouse) and wait for the driver
update wizard to complete; and now everything not only seems working fine, BUT actually working fine now.
thank you so much whoever you are.
regards and God Bless,
