Hardware USB port mod

[TariqSoftDev]

Well it's exactly as the titles says although here's the story behind this.
After I saw Yifan lu's amazing work on the MPCI-E SD adapter , I downloaded the eagle files and got the pin out for the PS Vita MPCI-E slot , from there I looked at the PS Vita GSM modem and realized the USB pins was all cut off from the PCB with two solder points , after this I did some work and added a USB port using some pins because I couldn't find a actual USB female xD

USB Connected(read notes)

UPDATE(MUST READ!!)
So after I yifan lu made me realise the most basic thing I missed (don't solder to the modem solder directly to mb) I fixed my error here are the pictures of the fix and the results.

New wiring layout:

Results that my PS Vita told me using Yifan lu's USB_detect/probe program:

Yeah I like spoilers UPDATE 2:

So I decided to add a proper USB port because pins aren't very practical :/, let the pictures explain the process.


The guts of it:

Spoiler

I had to get rid of a part of the PS Vita circuitry:

All wired up:

Finished look:

Note: Until a driver/plugin that supports this USB connection and mounting is created this is useless.

I also noticed that the PS Vita at some point (very early in me doing this) reacted to the USB and displayed a message "This device is not supported"(probably cause I didn't bother formatting to exFAT at that point)

I upload my work hours earlier on twitter: https://twitter.com/ZexceilXario

Remove this if statement. Recompile VitaShell. Then you should see the option to mount uma0. Select that and you can use your USB drive I think.

Alright I'm on it rn , I'll let you know how it goes.

My dev environment seems to be having a weird querk do you can compile it for me @yifan_lu ? , would be great help.

I won't have time until tomorrow but if you follow the directions in vitasdk.org and remove all previous installations you can just download the source and run

cmake . && make

Here's the error code , I don't seem to understand why it's missing that.

[yifan_lu]

You need to go into modules and "cmake . && make install" each one.

Alright so I compiled and installed , the option to mount came up but it won't recognize the USB via my mod . maybe I need to rewrite the code to use the USB 2.0 from the slot

 

[ov3rkill]

You should try and reach out yifanlu. He's making an sd card adapter which is inline with what you're doing, I think.

Did you format the drive as exfat?

 

[TariqSoftDev]

Did you format the drive as exfat?

Yeah I formatted it as exFAT just like the PS TV instruction , I unlocked the other mounting options but they don't do anything.

Just to make sure you compiled it right, can you install your build on a vitatv and see if USB mounting works there?

I don't have access to a PS TV although I'd happily upload the build and let anyone test it.

Also to clarify, did you follow the instruction exactly? First select mount uma0, then insert the flash drive?

Idk if it makes a difference.

Yep followed instructions word by word

Can you install/run this usb debug logging homebrew (rename .vpk.zip to .vpk)? Run it, press X, then insert your USB device and take a screenshot of the messages that come up.

I already compiled and installed that when I started I'll do that rn

I doubt you have the right version since it didn't work until literally five minutes ago.

Oh okay I'll use that one then , thanks alot.

So nothing showed up when you plugged in your USB drive?

Nope zilch~ , gonna use a arduino and the serial monitor to see whats being sent out.
