Odpojeni USB zarizeni

[Kaminar]

Ahoj,

chci se zeptat na jednu vec okolo odpojovani USB zarizeni. Na FreeBSD 8.1R
jsem mel pripojeny SATA disk (da1) pres USB adapter spolecne s externim USB
diskem (da0) na USB hub. Pak jsem oba disky odmountoval a fyzicky jsem
odpojil disk da1 od USB hubu. Ve vypisu na konzoli me prekvapilo soucasne
odpojeni i druheho disku da0 a jeho nasledne opetovne pripojeni (viz nize).

Chci se zeptat, jestli je toto chovani normalni?

Karel
