505 USB charging
Hello:
I bought a power to USB adapter, it plugs into the wall and has a usb socket. You plug your usb cable it it and the device in question and it charges them. After all, all usb devices are 5v. It works on everything I have (pda, ipod) - but not on my 505 - it actually manages to drain the battery of the 505! Any ideas what is going on here? This was supposed to be my charging solution on holiday, but so far it's a no go! What have Sony done to the usb and/or firmware to stop it charging from the usb? Do we suspect it is done on purpose so you have to pay their fee for a mains charger? |

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. |

I had a similar experience.
Interestingly, my PRS-505 behaves in the same way when plugged into my Fujitsu Stylistic (on which I haven't yet installed driver software to make it work). William |

This 'feature' has been noted many times on the forum here; a quick exercise of the search function will help.
In summary, the most reliable way of charging a Reader is through the PCP jack (the round yellow hole), and *not* through the mini-usb connector. You can use any generic Sony PSP charger, or a usb-to-psp cable, which can be plugged into a computer or any usb wall-wort or auto charger. The mini-usb port requires some level of communication with a computer to charge a Reader. And, the PSP jack charges more quickly anyway. |

Thanks for the info:
I knew people were talking about using PSP jack cables in other threads but never knew the unit refused to charge from a simple usb adapter. I have now ordered a couple of usb - to psp cables, hope fully this will solve my problem. |

etc. etc. etc. (Just in case anyone else misses this common issue!) General Reader charging advice: Use a PSP charger or cable (that fits in the round yellow hole) and NOT the mini-usb jack! It's faster and much less finicky. Last edited by DrMoze; 04-08-2008 at 02:34 PM. |

This should be made a sticky under Reader Troubleshooting.
Using PSP charger is the easiest. I have had Motorola phones/Sony Ericsson/WM devices/Blackberry devices that refuses to charge via USB from certain laptops/Wall plug usb chargers. Sometimes it is just the USB cable (yes, it is dumb, but I have no real idea why). The same failed device can work on another laptop too (But that is not the solution the user looks for) ps. I work in an IT dept, hence my constant exposure to these gadgets |
