i also posted about this kind of cord some time ago...
it didnt seem that anyone had any information regarding it.

the only problem with using a regular usb-type extension cable is it doesnt have the extra pins for audio, etc. that the htc proprietary accessories use. in short, the all-in-one adapter would only be able to pass through charging capabilities. so these mini usb extensions are a dead end...

we will just have to wait for an 11pin version.
