Hi All,
Some days ago I bought a 2nd hand mixer (PreSonus AR12c) which arrived in a miserable state. The biggest issue is that there is no actual USB C interface, meaning that the hole is there but it's empty. So, I've opened the case and I've found out that there is no USB C board... For some reason it was de-soldered or ripped apart (and then removed).
Now, I got full refund + I can keep the mixer. However, I have no use of a mixer without the USB interface, so I'd like to try to fix it by soldering a new USB C board there.
Can anybody help with these two questions?
1) The missing board was connected through pins called P1...P7 (see picture), while the USB C boards that I've found on Amazon have pin names like Ground, D-, D+, CC, etc.. and none with P1...P7. I am not familiar with naming convention of electrical components, so I'm wondering if there is any decoder to understand what P1...P7 means? Or, better, is there any USB C board sold with P1...P7 naming instead of GND, CC, etc..? I've already been in touch with PreSonus and they won't provide any info about this.
2) Is there any solution other than that to fix it? My soldering skills are adequate to work on large parts like resistors, etc.. but I'm not sure I can deal with such a minute contacts. Maybe replacing the whole board would be better? I do not wish to send the mixer out for repair because it will cost too much.
Disclaimer: I'm perfectly aware of the risks of destroying my computer and the mixer if anything goes wrong with soldering. I can take this risk (I have an old guinea-pig PC and I don't care too much about this mixer).

The p1 p7 p5 p6 are mechanic fixing point to hold the structure, so there is no circuit connections on it.
The rest three should be(not in order!) usb signal +, signal- ,and gnd. a basic usb2.0 port have 4 pins, since this interface won't need usb 5v power, the +5v pwr pin does not exist.
if you can paste a full and clear enough picture of the whole board, we can surely recognize out the defination of the three pins.

ground is gnd，d+ means usb signal +，and cc is 5v power，that's this should be in your search result.
