Hi Joe;
I wish I had know that before I spent $214.45 for the USB III.
I bought one a month ago and have had nothing but problems with it.
I spent 4 Hrs tonight trying to get it to work with HRD/DM780.
Wish I had known that the usable programs was LIMITED
My home brew interface worked OK for what it was ($214.45) cheaper.
On top of that the USB Router has been problematical since day one.
I got it working with MMTTY, but that's all I can use it for ???
That's a real bummer !!!
