PSP shuts off when plugged in through USB

[BigDaddyWeaves]

Hi guys BigDaddyWeaves here, EndlessParadigm is where you'll find my PSP theme work or even a quick search on here under "BigDaddyWeaves PSP CXMB Themes (Master Thread)"
I've run into a little problem while building my Darth Vader PSP Persuader theme and was hoping someone could guide me to a solution.
The PSP shuts off every time I plug it into USB mode, every time. Without fail. I wonder if I have too much shoved into the theme? PRX or RCO.
Anyway it shuts off and I can't do anything about it I even tried a different battery (thinking it was the battery but nope,) it's THIS theme.
Here's what I got so far:
I'm thinking the problem lies in having too many PRX's but unsure as to what to get rid of as I don't want the format of the theme to become lost.
ANY help would be greatly appreciated.

Things I know I can't delete are:
paf.prx
vshmain.prx
opening_plugin.prx
common_gui.prx

These ^^ files I believe are essential to the theme's overall UI.

I'm not into PSP themes, but about the PSP's USB, I can say a little about it.

Check your theme "elements" resolution and color depth as it might break the screen resolution reported to the connected screen if you're using one. That might cause the shut down.
