Hello and thanks for the info. WIN 7 recognized the mic one time. I went through the WIN7 ARC pdf file and was able to do all that was instructed. I then started ARC and ran it manually to run Quick Measure. I am using the Keyspan adapter so there is no problem talking to the AVM50V 3D. I did run across what you mentioned but figured out when it told me to select the mic that matched the serial number that I needed to actually highlight that mic. Okay so once I did that and started Quick Measure, I got an error message that said to check for a bad connection on the USB cable or something to that effect. Everything seemed connected so I exited ARC. When I clicked on the audio properties Recording Device it said none was present and that is where I have been for today. I was able to check the mic and cable by installing it on an old desktop WIN XP machine so the hardware and cable are okay.
In WIN7 I have been disabling the Firewall and Virus Scan and still to no avail. I can uninstall ARC, re-boot, re-install ARC and in Device Manager I see an USB Audio Device with the Yellow error symbol and WIN7 gives the standard "Device Cannot Start (Code 10)" message. When I check on the properties of the mic and tell it to Update Drivers and point the the ARC 3.02 folder including searching sub-directories if memory serves it says the drivers are current.
I am thinking the maybe there is something in the Registry that needs to be deleted and maybe just uninstalling the mic doesn't force a new driver installation.
So I'll call Tech Support tomorrow and they will probably say "oh yea, we've heard of that so try this". I work with firmware guys and they tend to say that all the time
Again, thanks to all who have been following my short journey. I am converting my theater from all analog to digital and am having some luck. Kind of like that new Joe Walsh tune Analog Man
