Pro tools MP9 sound card for more than 2 recording tracks.

[TenukiMind]

Hello every one, I hope every one is doig well these days !

I'm recently new on DAWs and with PT especially.
I have a m-audio bundle, with the Mobile-pre sound card, and PT MP 9.
Running on win 10 with a decent computer (8Go of RAM).

The version of PT I have can record more than 16 track simultaneously and I dont see any limitation for the use I have so far inside the software.

The problem I have is that I can only record two mic tracks, due to the fact that my M-audio mobile-pre only has two imputs...

Is there any way to use more than 2 tracks with another hardware ? I understood that only this sound card let me able to lauch PT, in fact if the m audio is not there PT refuses to lauch/work. Is there a way to make the m-audio work with PT and having another hardware working with PT simultaneously ?

Maybe these questions are beginner-like but I asume I'm a bit lost on this, and my drums wait being recorded !

Thanks a lot in advance for any further help yu can give me.
Respectfully
V.

EDIT : - I forgot to mention I only have usb available (no firewire but can be change if it's the only way I can change my computer)
- sorry if my thread is not in the good place inside the forum or if the question has already been answered, the forum is pretty huge !
