Do you hate having go enter USB mode just to copy a few little things???  Well then today is your lucky day, A PSP coder by the name of vodkkaa has just released a plugin that lets you be in USB mode anywere in the XMB, and this plugin also includes the 4th 4th brightness for 3.03 OE users ( which if you ask me just runs your battery dead super fast).

Here is what QJ.net had to say

QJ Wrote:Haven't heard of such plugin? Well, there isn't exactly one that's why the coder created the USBon Plugin. The name of the application is pretty much self-explanatory. With this plugin, you will never have to go to Settings then activate the USB mass storage function as you can do that  by giving the right shoulder button a quick press. Some other features of this include:

    * For 3.03 OE and 3.10 OE
    * Quick toggle of USB Mass Storage
    * USB connection anywhere in the XMB
    * 4th brightness for 3.03 OE users

In the event that you have another plugin installed to your flash0 (and wee believe you do), take note that you will need to add them to the "pspbtcnf.txt" before flashing. Speaking of which, you already know the drill: don't tinker with these things if you don't know what you're doing.

Flashing any kind of file to your PSP runs the risk of bricking. Read the accompanying Readme file for more details and instructions.

Enjoy

yeah but flash0 is a readonly file, i tried changing it with usbsss and it said it can't be changed, so u can only change ur flash0 in recovery menu.

^^ Which is wise, methinks.

i like this plugin but does anyone know what the code is for in usb.txt to make it enabled/disabled on the L-trigger instead of the R-trigger? cause i already have the battery plugin for the R-trigger :)

it should be the same as the battery thing just try to go under the file that this plugin has and test it out, the worse thing that can happen is a frozen psp

usb.txt Wrote:enableUsbMass = false;

comboButton = 0x0x000100;

startStopUsbmassEnable = true;
startStopUsbmass = 0x000200;

what i meant was that in the usb.txt (for the seplugins version) as seen above ^^, it has the "startStopUsbmass" which i guess is the button that activates it, which is the R-trigger. i want to know, how to change it from "0x0x000200" to a code for the L-trigger. does anyone know/or can figure out the code?

Lol, they're very good aren't they?  I guess the code is based on the button masks - perhaps search up the PSP_CTRL_ constants or something if you want, but I'd bug the author of the app instead. ;)

If you don't mind fiddling around, you could also consider this, bitmasks work like this:
0x0001, 0x0002, 0x0004, 0x0008, 0x0010, 0x0020, 0x0040, 0x0080, 0x0100 etc etc
So just choose values based on the pattern.
