Can't connect to PC via USB - Galaxy S 4 Active Q&A, Help & Troubleshooting

Hello every1.
I have a problem here.
When I plug in my USB cable to my S4A and connect it to PC, I get only charging and NO USB CONNECTION.
No USB debugging, no anything but phone charging.
Anyone has an idea what of system files should I look at for that?
I've tried SG Mass Storage enabler (https://play.google.com/store/apps/details?id=com.mohammadag.samsungusbmassstorageenabler) and after that it stop connecting.
What does that app do and change, so what should I revert to stock state??
Please help.

Some Windows setup needs to be repaired to properly identify USB connected hardware. I have a link to fix it in my thread

Check in your ActiveSync settings on your device and make sure you don't have it set to Disk Drive Mode. Otherwise, there may be an issue with your PC's OS. Have you tried connecting to another PC?
When you plug in the usb cable do you get the pop up on the diamond asking which connection type to choose (activesync, disk drive, internet sharing)?
Go to AS on the diamond - menu - connections - check the box, if not checked to sync the phone thru USB.

[Q] My SGS USB device failure

When I connect my usb cable to try and connect my SGS to either my XP PC or laptop or to my Mac Mini it doesnt work. Nothing at all happens on the MAC but on the windows devices it tells me there is a USB failure. I cant connect even in mass storage mode. Never mind in Kies.
Its very frustrating as I cant put anything on my phone. Strangely lately it was asking to choose Kies, Mass Storage or media when the mains charger was plugged in.
Any ideas greatly appreciated. Tried a factory restore but it is still the same.
Kies reinstall/update drivers .

MTP initialization

This question is all over and i'm a lil lost. I just got my 7.7, stock P6800. I plug it into my mac and there's this cross on the batt on the device. I'm assuming it wont charge with the USB cable that came with it. So i went to buy another. Same problem.
I installed Kies on my mac and it can sync tho. I just can't seem to be able to mount it to my mac and transfer files like a USB drive.

have you tried turning off usb debugging?
also the tab won't charge with the usb connected to the pc cuz the charge voltage is too low.. you need to modify your build.prop to force usb charging or flash sk806(steve's) custom rom
yes i toggled USB debugging on/off. :S

USB charge only problem

Hi!
I have a problem with my Lenovo K3 Note.
Can't transfer files from PC using USB cable (it only charges). Computer doesn't recognize and no notification or option to change connection type on Smartphone.
The only way to connect to PC via USB is when i have TWRP recovery open. In this case i can transfer files, etc
Already tried in different computers with different cables and with USB debug on and off.
Any help would be very appreciated
Make sure your device's screen is unlocked.
Connect your device to your computer using a USB cable.
On your device, pull down your notification drawer by swiping down from the top of the screen.
