usbmc (ux0+uma0 mod)

This is VitaShell's patches for USB storage support as a standalone plugin. If loaded on startup (before SceShell), it will automatically mount the USB storage as ux0 instead of the memory card or internal memory. The memory card or internal memory will then be mounted to uma0 by default.

Full credits to The_FloW for the patches and Yifan Lu for usbmc.

This is NOT for gamecard-to-microSD adapters! For that, you want to check out this.

Note: When using USB storage as memory, make sure all taiHEN plugins are installed to ur0: with ur0:tai/config.txt as the config file. This is because taiHEN is loaded before usbmc so you cannot use taiHEN plugins installed to USB.

Installation

1. Download the latest pre-built release (usbmc_installer.vpk) or compile the source yourself.
2. Make sure your USB storage drive is formatted to a single FAT, FAT32, or exFAT partition using the MBR partition scheme.
3. Install the usbmc_installer.vpk.
4. Run usbmc to start the installer.
5. Press CROSS to install the plugin.
6. Reboot

Now you can use the USB storage as a replacement for your memory card (or internal memory) at ux0. Continue reading if you want to transfer the content of your memory card (or internal memory).

1. Start your Vita with SQUARE while holding down SQUARE to swap mount points.
2. Open the usbmc installer again.
3. Press CROSS to start the memory card installation (Install USB as memory card.).
4. Choose to either copy VitaShell/molecularShell to the USB storage or copy everything from your memory card to the USB storage, replacing any files already on there.
5. Once the copying is complete, press X to shut down the Vita.

Installation (if you already installed the original usbmc by Yifan Lu)

1. Download the latest pre-built release (usbmc.skprx) or compile the source yourself.
2. Replace the original usbmc.skprx located at ur0:tai.
3. Reboot

Usage

• On boot, the USB device will be mounted at ux0 and the memory card (or internal memory) at uma0.
• If SQUARE is being held down on boot, the mount points will be swapped for this session. Reboot to go back to normal.
• If no USB is found within a few seconds, the memory card (or internal memory) is mounted at ux0.

Uninstallation

1. Remove the USB storage or start with swapped mount points (see Usage section).
2. Install the usbmc_installer.vpk if necessary.
3. Launch the installer and use the TRIANGLE option to uninstall the plugin.

Note you cannot uninstall usbmc while it is in use (duh).

Disclaimer

I can only test this modified version with a PSVSD v2.1 on a PCH-100x (PS Vita OLED 3G). Therefore, I don't know if this functions properly when used on a PSTV. Sorry.
