I own a Mic AT2020, a Studio Mic, right now I use a USB-B to USB-A for it, I used it for about a 1-2 years now.
But I feel like I don't have that control over the mic I want to, so I was looking for if you could get a USB-B or A to Jack
So I could plug it in my soundcard, and then have a little more control over it.

This wouldn't work, because USB carries digital audio while 3.5mm jacks are analog. Unless I'm missing something... The cable itself would need a DAC chip in it.

yeah I give up finding a way to use USB to Jack so I just order the same mic AT2020 with a XLR input and then use a mixer as a main station between the mic and sound card
It's literally impossible to convert USB back to analogue audio like you originally wanted, the mic needs an actual USB host to connect to that also has the required drivers to make it useful.
When looking for microphones such as these it's best to choose ones with either an analogue bypass/line output or just get a standard analogue mic with a separate mic ADC or soundcard.
Depending on what soundcard you have, it may also already support balanced mic (ie XLR) input and all you need to do is switch said card's input to balanced and use a phantom power injector if the mic needs it. Many X-Fi cards support this, some also with their own XLR jacks so you don't need an adapter cable (XLR to 3.5mm).

Phantom Power Injection, via soundcard, is *not* a replacement for actual phantom power. It will not run a microphone that requires phantom power properly. Also, even if your soundcard had an XLR connector, which only pro cards have, you would still need a seperate pre-amplifier/phantom power supply to properly drive your micrphone.

Do you know what a balanced audio signal is? Some soundcards support it and all you need other than a power injector is a XLR to 3.5mm cable, the cards that support this (usually) also already have an internal mic amp (+30dB).
Phantom power is a +48V standard on the hot pin, you can make an injector yourself if you want, just need a 48V power supply and a DC filter.

Except that Soundcard 3.5mm jacks are Unbalanced, on the majority of commercial soundcards. Yes, there were a handful of cards that had a proper mic amp and +48v Phantom Power. Most of those were discontinued.
Oh, and +30 dB will *not* drive any proper microphone at any reasonable level.
I don't know about all that ^_^ since it the first time I own an XLR mic; I own a Creative Labs SB X-FI Titanium Fatal1ty. Personal I'm not happy with it, I may go to get a new Soundcard at one point right now I use the build in since I like it better than the sound card I have now.

Phantom power and balanced audio are two completely different things, and I already stated that some/many high-end soundcards provide a balanced mic input, my X-Fi forte is one of them.
The phantom power injector is plugged between the card and mic and supplies 48V down the mic cable, but not to the soundcard. The soundcard is then fed balanced audio from the mic's internal amp, over the injector and into the card's pre-amplifier.
+30dB is a pre-amp setting on the card, ie; the physical pre-amp gain before entering the ADC, it doesn't "drive" any external device...

...I never said they were the same thing? All I said was that 3.5mm Jacks on consumer soundcards all expect Stereo and, thus, are Unbalanced.
Perhaps "Drive" wasn't the correct word, but considering a Line level Mic signal *needs* to be amplified in order to actually be usable... I thought it would be the right choice.

This doesn't make sense. Microphones don't have "Internal amplifiers". Also, are you totally sure it uses a seperate, proper, pre-amplifier stage? The majority of cards just apply digital gain after the fact.
Not that I can even find a manual for your card to check for myself. X_X Either way, this is getting off-topic...

For a mic to provide a proper balanced signal over the cable it needs some basic circuitry, commonly a single stage amp of very little power. Passive mics (like most computer mics) lack this and as such don't require phantom power, however they generally are only wired to the hot pin and the cold pin is just grounded, so as such they are subject to noise. Unbalanced line connections (eg; a guitar) are the same because their pickups collect enough power to not need an internal pre-pre-amp, nor are they subject to much noise (unless you have a dodgy cable), instruments that require power also tend to use a 9V battery with more complex circuitry just for convenience.
As for my card, it just has two 3-pin headers for switching it between stereo unbalanced and mono balanced, when a pre-amp is already stereo all you have to do is invert the cold wave and mix the two together after amplifying it, of which one header would control the wave inversion and the second the mixing.
I am about to post a thread about this... The mic jack on most sound cards puts out between 2 and 4.5V to power up headset microphones.
