[Galaxy Ace S5830i Q&A, Help & Troubleshooting] ehsanotaku:
[MENTION=5870728]LiQuDiAk[/MENTION], Hasty actions are done in a hurry, sometimes without the necessary care or thought. Now let's not leap to any conclusion about your Android custom Rom and flashing back to stock. lets focus on your first most obvious problems,which is driver related.

You didn't declare your flavor of windows: i.e: Windows x86 based-PC;professional 7

Not so sure of your OS Name/Version and System Type, search "system information" in your search box.

Your task manger depicted ACPI x64 ( 64-bit system, no wonder previous 32-bit compatible didn't work out for you ).

Symptoms observed so far:

1. USB cable only charges ( remember your USB cable data line might be the culprit. Just in case of only charging,checking with another set recommended. Your USB port might be problem, some dirt or faulty data line, checking with another USP port doesn't heart though.

2. Windows recognizes something more (like in your case, struggling to find proper corresponding driver), but cannot see it as a Samsung android device (cannot allocate the installed USB drivers to the device).

-If you got Kies (Samsung proprietary software) installed on your PC, delete it with a descent uninstaller program such as CCleaner free version .Kies might cause driver conflict , use it as only last resort , if all drivers failed to communicate with s5830i device.

-Also Uninstall your previous given driver same way, now restart , back to system and grab set of universal Samsung Drivers from attachment .

3.Can't see your "USB connected" in Android notification bar, so you cant click on it and mount your storage data part while you are connected to your PC.

-Normally, when you plug in your Android device, Windows will recognize it as an MTP (Media Transfer Protocol) device and quietly mount it.

However, if you’ve ever attempted to unlock your device such as to install a new ROM or root it, then such miss behaviors might be expected occasionally .

Before i go for more troubleshooting , please provide a full screenshot from your "About Phone" page in your settings . I am quite curious about this phoenix Rom you have mentioned though . I am quite familiar with at least dozen of discontinued/ported projects, but never heard of such ported Rom from other models into s5830i .

Couple of solutions :

Navigate to your settings,Storage and touch the upper-right corner for the “USB computer connection” options, if you have this part available.

make sure “Media device (MTP)” is selected. ( if you have USB Utilities section or whatever added section in your custom settings go there . Selecting that will do the trick. If it does not, then you likely have a driver problem.

Open your device manager, Right click on your unrecognized device in question,choose update driver software, choose Browse my computer,find it through given x64 drivers in your package ,Restart. ( After a successful installation, restart your PC, you must have something like the picture in attachment ) .

Problem was not resolved, Uncheck your debugging option,power off your phone. Now hold Volume(+) + Home + Power for a couple of seconds simultaneously to get to your Samsung Recovery or your Clockwork Recovery, choose Reboot( might be some process/service in your background, which interfere with your Auto USB connected feature of your device. See if the problem is being resolved .

Problems have been persisting, we might need to format your SD card, but before that, insert it into your card reader, in your file explorer window choose Tools>Folder options>select view tab> tick your select hidden file.folders. Now copy all of your SD card's contents into some folder, safe inside your PC.

We can format your card through your clockwork mod recovery console, or some partition tools such as free mini partition wizard,,

problem still persist? let me know :)
