Cuando conecto la unidad USB 2.0 veo esto:
usb 1-4.3: new full speed USB device using ohci_hcd and address 5
Entonces sé que lo ven como USB 1.1. dispositivos USB muestra que realmente es USB 2.0 y está conectado a un concentrador 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 el problema es que el concentrador raíz es:
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
Y no se menciona ehci_hcd.
lsusb -tme da:
/: 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 me falta algo que permitiría al sistema operativo ver dispositivos USB 2.0. ¿Alguien puede indicarme la dirección correcta?

me parece que el disco está conectado a un hub usb 1.1
¿Puede dar más información sobre las conexiones entre el disco duro y el puerto USB?
