Hi guys - this is with the new USB version of the mount and V5 hand controller.
I installed the newest PL2032 (or whatever) USB to serial driver. I'm holding 0/8 on the H/C and plugging from USB on the laptop to USB on the H/C. It starts up and says "Synscan Update Version 2.6". I hear the "ding" in Windows, and in Device Manager I can see the port show up - COM 3. However, when I click "Check H/C" in the firmware updater program, it fails to find a H/C. This is both with "Auto detect" on and off and manually choosing COM3. Motor controller updater doesn't work either.
I have the ASCOM platform installed, and I also installed that ASCOM driver from the SW website.
