This may be known to some people. I recall vague mention of USB problems on various mailing lists. But, nothing specific. Although this sounds like a very serious problem, I don't see any bug report in <http://jackit.sourceforge.net/mantis>, the JACK Mantis database. If it makes JACK useless, someone should report it, providing enough information for developers to work on the problem. Regards, -- Jack O'Quin Austin, Texas
