Can't open USB card if it's plugged in on power-up

Here's a new, weird issue.

I'm using KXStudio (which means, 14.04 + KDE) and have been using a variety of USB soundcards with (almost) no issues. Currently, it's a Native Instruments Komplete (NI-K6).

All of a sudden, if the NI-K6 plugged in to the USB port when I power on, Jack (via Cadence) can't open! If I unplug it and switch ports, then it works. It doesn't matter which port - I have to put it in the OTHER one to make it work. Additionally, my MIDI devices won't show up. So I've been starting Cadence with built-in speakers... stopping it... plugging in the NI-K6... restarting it with the NI-K6... and then it works, and I have my MIDI.

I am up-to-date, and haven't done anything very strange. Well, I DID try to install Ofelia for Pure Data, and let it install a new Jack2, before I realized it needed Ubuntu 16 or 17 to run. I think it's the same Jack2 that I'd get from Synaptic. And I'm fully up-to-date (for 14.04/KXStudio).

Any ideas? It's annoying! Not horrifying, but it certainly adds time to set-up for shows.

Thanks.
