Does anyone know if the Nokia CA-101 cables are already shorted in this way?

I have connected this directly to many desktops / laptops. I have connected to car charges with USB female sockets (originally for iPods/iPhones). I have connected to wall charges with USB female sockets (again for iPods/iPhones) and all seems to be working fine.

Perhaps this is the simple solution? Buying Nokia original cables... I got them of eBay for about £1.50 delivered.
