Thank Charles Curley! my usb hub hasn't external power supply, i don't think loose connector cause trouble because it's ok with buster and bullseyeTwo thoughts here. * Does your hub use an external power supply or does it depend on the computer for power? If the latter, that could be a problem if the total load exceeds what the computer supplies. * It could be just a loose connector, although I haven't seen that in a long time. It is possible to fix this for some types of connectors (RCA connectors being particularly susceptible) by crimping the connector very lightly with a pair of pliers.
