I suspect that it's down at the details of the USB protocol & I'd not like to guess which is doing the 'right' thing. I know that there's something about there being supposed to be some form of device negotiation to verify a particular level of protocol support before a device is allowed to try & use the max current that the specification allows, so maybe it's trying to do that & failing to get the response it expects.

Personally, I bought a cheap generic (i.e. non-Sony) PSP charger & use that, which has the advantages that it charges quickly & also allows me to read while it's charging.
