Two 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.
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 bullseye
