Hi Folks.

I have been trying to get the HS-USB Android Diag/Modem/Serial ports activated so that they show in Device Manager, to no avail. I am using Windows 7 on my PC.

Is there a special number sequence i enter into the dialler? Or is there a special USB driver i have to install? I am able to to activate these ports using my Samsung S4, so surely it is possible for the Xperia Z3?!

I remember successfully doing this on an earlier Xperia phone, but cannot remember how i did it.

Would be grateful for any help please.

Thanks in advance.
