You'll probably want to pipe it's output to your favorite > pager. "sysctl kern" will list just the entries in the kern MIB. OIC. It's not available until the device is pluged in, which makes it absolutely useless. When I plug it in the machine behaves abnormal, so I need to set it BEFORE connecting USB devices. Why has this tunable by default a value which makes the machine unstable by every umass I plug in which has no "qirk" entry? And if I look how many quirks there are I assume that almost every device needs no_6byte set. Why not make it default? Perhaps this would prevent criminal people from intentionally crashing servers when intruding my serverroom armed with dozends of USB devices;) -Harry > > Regards, > > > Andre Guibert de Bruet | Enterprise Software Consultant > > > Silicon Landmark, LLC. | http://siliconlandmark.com/ > >
