Exactly - it's a hardware problem. > could anyone from FreeBSD USB people *please* comment on that? I've seen this kind of problem with several different hardware combinations - it is not specific to Bluetooth. One case known to me is a notebook internal MMC reader, which always fails that way unless you connect any other device to any USB port. In general it's a broken device which doesn't work within the specs if triggered by EMV noise or whatever. Very often this kind of problem is triggered by notebooks. I've seen cases in which the oscillator design was just crap. Normaly I would say: "drop it into your favourite wastebin", but Windows shows us that it's possible to work around this kind of hardware bug. > i still have all traces available at > > http://www.geocities.com/m_evmenkin/usb/ > > in fact this option stop working for me today :( i do not know what > happend but it worked a couple of times yesterday and now i'm back > to "device problem, disabling port 1" > > thanks, > max > > > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org" -- B.Walter BWCT http://www.bwct.de ticso@bwct.de info@bwct.de
