hello. I'm having an issue with qcma as well cma. whenever I connect via a usb cable, I can't connect. I don't understand what the problem is. the computer is receiving the connection based on the audio cue, but no connection is made. I've tried using libusbk, and a different cable. I've also run revo uninstaller to remove all traces of previous qcma and cma versions. I don't have both installed at the same time either. it doesn't make sense.
