It should be remember that homebrew developer SG57 released the plugin VSHInform Alpha. It concerns your PlayStation Portable's (PSP) frequency and USB function among others. While the program is really nifty, some users reported that it won't work on certain custom firmwares like 3.10 OE-A'.

It seems that the coder noticed the problem and that's another version of VSHInform. It is still in Alpha but SG57 noted that this should work with custom firmwares 3.xx OE. The plugin is very useful in informing users about their handheld's battery percentage, battery life, CPU frequency, and USB On/Off. It also allows the following:

* Change CPU frequency between 4 pre-defined values
* Turn USB on/off with the touch of a button
* Turn on/off the visibility and button input of it
* This may be used in both the VSH and in a game

VSHInform Alpha for 3.xx OE has a Readme file that contains information on installation instructions, controls, and other important details.
