It is very similar to JaicraB’s USB Firm Loader, with a few tweaks for people with USBs that have different numbers.
For those of you unfamiliar with these type of apps, they load custom firmware by mapping dev_flash (where your firmware is normally stored) to dev_usb (your usb ports). This allows you to place custom firmware files onto a usb stick and have the PS3 utilize them.

Features:
Choose what USB to use!
Redirect dev_flash to usb
Redirect app_home to usb
Dump LV2 kernel and mount points
...along with all the source code that does it
!!!NOTE!!!: You need a payload with peek and poke syscalls (PL3 dev has this)
Usage:
X - (Un)Patch /dev_flash as usb
Square - (Un)Patch /app_home as usb
Select - Dump lv2.bin & mounts.bin to usb
Up/Down - Change USB
Triangle - Exit
The dev_flash files have to be on the root of the USB drive to work, e.g. if E:\ is your drive, you should have E:\vsh, E:\vsh\modules, etc...
Make a PS3_GAME folder on your USB for the thing in the Game menu to work.
App has some bugs, but it is my first PS3 program
