      I have installed all needed drivers, I am concentrating on a XP machine. I would love to have another ham look, if there was another in my area(Tri-Cities Wa, USA) that has built a SoftRock I would gladly take it to them.

      > Just for clarification. You have installed All the required USB drivers right? You absolutely can't do anything until they're all installed. That means the Lib driver and, in the case of Windows 7, a signed certificate. As far as plugging it in without the chip- I do know that some of the newer machine sense things plugged into the audio ports via a mechanical switch. I wouldn't assume that means much. I would focus on a machine with XP, install the proper drivers and go from there. Another idea is trod your rig to someone nearby that has a working system to test it. where are you located?

I believe the issue is in the hardware, I have since pulled(un-soldered) all the resistors and double checked them against both the component lists and with a meter, everything checks out. As I have said before I get the same error when the ATtiny is not in the socket, which I believe the PC should not detect anything was plugged in when the ATtiny is missing? Or am I incorrect in this assumption? Kind of at a loss here, I have built many kits, worked as a instrument tech, so I know most likely I missed something but I simply can not find it. Is it possible that my bill of materials for this section is wrong? Could the T1 in the circuit cause issues?
