Hello,

I'm back on the track concerning that "problem"…
But first of all, Happy New Year to you all.

Device tested : PRS-650 purshased directly from SONY France way back in Nov 2010 ( I'm actuality abroad for awhile ).
PC : Windows 7 & Windows XP Pro.
Charger : Generic European USB : Input : 110 – 240 VAC – Output : 5 VDC – 500 mA

1 – Charging the Ebook with the Sony provided cable and thru a standard USB PC port works fine :

2 – Charging the Ebook with the Sony provided cable, but with D+ and D- signals neutralized, and thru a standard USB PC port does not work :
USB connected msg visible but NO charging advice msg; 30 sec. later, error msg related to charging failure.

3 - Charging the Ebook with an USB generic cable and thru a standard USB PC port works fine :

4 - Charging the Ebook with an USB generic cable, but with D+ and D- signals neutralized, and thru a standard USB PC port does not work :

So, based on the different readings and advices, I wonder if we don't face a software restriction there ( for the products sold overseas ) , since test points 2 and 4 really reveal that the signals D+ & D- are for some reason required, and even mandatory.
What I wasn't able to check so far, is testing with a mobile charger equipped with a micro USB connector.
So quid ?
Any idea ?
