USB hub a nefunkcni pripojene zarizeni

[Zdenek SUTR Kaminski]

Dobry den,

  koupil jsem 7mi portovy usb 2.0 hub s externim napajenim. Po zapojeni do 
pocitace se mi objevi v dmesg:

coz je v poradku.

Kdyz pak pripojim mys do nejakeho portu, tak vidim v port styatus zmenu 
na:

  Hub Port Status:
    Port 1: 0000.0100 power
    Port 2: 0000.0100 power
    Port 3: 0000.0100 power
    Port 4: 0000.0100 power
    Port 5: 0000.0100 power
    Port 6: 0000.0103 power enable connect
    Port 7: 0000.0100 power
    Port 8: 0000.0100 power

coz je asi take v poradku. Nicmene mys neni dale rozpoznana a 
nefunguje.Pri zasunuti do portu v hubu mys blikne a dost. Pri zasunuti 
primo do usb portu na desce, kam chci jinak zasunout hub, tak mys blikne a 
zacne trvale sviti a je rozpoznana

usb 1-3: new low speed USB device using ohci_hcd and address 3
usb 1-3: configuration #1 chosen from 1 choice
input: Logitech Optical USB Mouse as /class/input/input3
input: USB HID v1.10 Mouse [Logitech Optical USB Mouse] on 
usb-0000:00:02.0-3


a funguje. Kde delam neco spatne? Mel jsem za to, ze na usb hubu neni 
zadna magie.

Pouzivam FC5 s aktualnimi updaty. a vyse uvedene chovani je jak na 
notebooku (centrino), tak na stolnim pc (amd64).

Za kazdy dobry napad diky.

Z.K.
