Ubuntu 10.04 reconhecendo HD externo USB 2.0 como USB 1.1

Question

Quando conecto a unidade USB 2.0, vejo isso:

usb 1-4.3: new full speed USB device using ohci_hcd and address 5

então eu sei que está sendo visto como USB 1.1. usb-devices mostra que realmente é USB 2.0 e conectado a um hub USB 2.0:

T:  Bus=01 Lev=01 Prnt=01 Port=03 Cnt=01 Dev#=  2 Spd=12  MxCh= 4
D:  Ver= 2.00 Cls=09(hub  ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
P:  Vendor=05e3 ProdID=0608 Rev=77.61
S:  Product=USB2.0 Hub
C:  #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=100mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=hub

T:  Bus=01 Lev=02 Prnt=02 Port=01 Cnt=01 Dev#=  4 Spd=12  MxCh= 0
D:  Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
P:  Vendor=13fd ProdID=1340 Rev=02.10
S:  Manufacturer=Generic 
S:  Product=External
C:  #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr=2mA
I:  If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage

Parece que o problema é que o hub raiz é:

T:  Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=  1 Spd=12  MxCh=10
D:  Ver= 1.10 Cls=09(hub  ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
P:  Vendor=1d6b ProdID=0001 Rev=02.06
S:  Manufacturer=Linux 2.6.32-25-server ohci_hcd
S:  Product=OHCI Host Controller
S:  SerialNumber=0000:00:02.0
C:  #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=0mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=hub

E não há menção de ehci_hcd.

lsusb -t me dá:

    /:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ohci_hcd/10p, 12M
    |__ Port 4: Dev 2, If 0, Class=hub, Driver=hub/4p, 12M
        |__ Port 2: Dev 4, If 0, Class=stor., Driver=usb-storage, 12M
        |__ Port 3: Dev 5, If 0, Class=stor., Driver=usb-storage, 12M
    |__ Port 6: Dev 3, If 0, Class=stor., Driver=usb-storage, 12M

Parece que estou perdendo algo que permitiria que o sistema operacional visse dispositivos USB 2.0. Alguém pode me apontar na direção certa?

Answer 1

parece-me que o disco está ligado a um hub usb 1.1

você pode dar mais informações sobre as conexões entre o disco rígido e a porta usb?
