I am attempting to register my PSP to my PS3 system via USB.
I go to Manage Account - > Register System -> PSP, plug in PSP via USB, initiate USB Mode on PSP. However, the PS3 does not recognize that the PSP is connected. It keeps telling me to turn USB Mode on.
I have the latest official firmware on both systems. The PS3 can see the PSP memory stick via the XMB but not the PSP itself.
I am at a loss. Any help would be appreciated.
What, exactly are you trying to do? Your post doesn't make much sense.
You say you went to Account Management > Register System, but under account management you can only activate or deactivate systems. So you would see System Activation. There is no "register system" on the menu.
If you are trying to activate your PSP to your PSN account, you don't really need to do that manually, it usually happens automatically when you download anything from PSN, or transfer it from your PS3 (provided both are using the same account).
Or are you trying to set up remote play (there is a Register Device setting under remote play)?
Everyone thinks I'm psychotic (except my friends deep inside the earth).
