As you know, Psp'camera use the two sheet metals beside the usb interface to supply power,and now i want to use them to supply power for
my own deivce,but i don't know if there is a function to control the power on or off, and what function i can call.

It's a bit old but I got someone to make a PRX Plugin to enable the power using L+R in the XMB way back.

Not sure if it works with current firmwares...

Thank you for your reply, and it must be useful.
It seems there still some problem when set usb power on as the author said.
If there is a system call such as 'sceSetUsbPower()' , it would be an easy way to set usb power with my own software.
Thanks for you help!
