Hi!
Okay, so what is the problem at the moment? Did the PSP failed charging and won’t do anything? Or does the USB failed?
First of all, do you have a new battery? If not, this is probably the first thing you need. When you did bought a new one, and it won’t show the orange light when you have the charger in, return it and get yourself a new one. If this also failed, then you might want to check the charger it self or the charge plug inside the PSP.
Is the PSP modded by any chance?
