Just a thought: I have a known bad USB sound card, it has a tendency to overheat after 'x' amount of time, (varies) depending on ambient temperature and air flow near it. The system (linux or Windows) loses it. I can restart USB discovery and it usually finds it again, or I can unplug and re-plug it in and it gets rediscovered. Logs seldom gave a reason. I only use it for testing now (I hate to throw away anything, I'm a hoarder) but not for anything long term.
