I'm using an old CPS (6.5), but that hasn't been a problem before. I have tried installing various drivers, and have reinstalled the CPS, but nothing has worked so far. The radio seems to be recognized by Windows (Device Manager says the device is working properly). When I attempt to read/write the radio in the CPS, I get error 1687 or error 1689 (unable to detect applicable device).
I recently installed Windows 10 (an upgrade from 7), and cannot get my XPR6550 radio recognized by the CPS.
