My Phone will not recognize USB connected There is no USB options when I connect to pc. I have tried a Galaxy Avant phone with the same cable and works, so it is not the computer or the cable. I have turned off and on USB debugging. I have tried so many " solutions"  and still nothing.

Phone: Rooted Galaxy Avant (T-mobile)
Kitkat 4.4.2
First of all, please make sure that you have latest Samsung USB driver installed on your computer, if not please update it or download latest version from this page.
Second, make sure that USB cable is working properly.
Third, if USB cable is ok, driver is up-to-date and you still won't able to connect, then type in your Phone app this string *#7284#and check the option MTP + ADB, press save and reset. This should solve connection issue.


P.S. If appeared *#7284#  "service screen" is different which means you can't see the MTP + ADB option please post the screenshot here.
