It isn't obvious, but you must select CMA protocol version "FW3.30" for all 3.3x firmwares, "FW3.10" for all 3.1x firmwares and so on. Also, you must use Offline Mode in all cases except when you're trying to update to the latest firmware.
So in order to connect your Vita to QCMA using USB cable:
Put QCMA in offline mode with the correct protocol version set.
Put Vita in airplane mode (with Wi-Fi disabled), turn it off and back on.
I personally have near 100% success rate on my 3.18 Vita when I try to connect to PC via USB with a disconnected USB cable, wait for "Can't connect to PC" error to appear, tap "Yes" on "Is CMA installed on the PC?" prompt, then connect USB cable, and only then tap "Connect".
