I just bought a 200 Gig- USB 2.0 Harddisk (Trekstor Datastation maxi y.uh ;140 Euro).
As my Notebook just has an USB 1.1 -port, I also bought a PCMCIA to USB 2.0-adapter
(Sitecom USB 2.0 PC Card CB-003V2 ;30 Euro).
Plugged it in, attached the harddisk.
Startet MUT, and the harddisk was visible and could be mounted (great, Mandrake-Linux 9.2
does not recognize the USB 2.0-Port).
Then I copied a large file: awfull slow.
So I ran the "usbview"-Tool.
It tells me something about ohci and 12 MBit.
Well, USB 2.0 supports 480 MBit.
Watching the booklet, in the specifications it sais:
"the device consists of two openhost Controller Interfaces (ohci), and one Enhanced Host
Controller Interface (ehci)".
So I looked for a module:
ls /lib/modules/2.4.29/usb/host
ehci-hcd.o.gz uhci.o.gz usb-ohci.o.gz usb-uhci.o.gz
Ah great, right what I need.
modprobe ehci-hcd
and *whoooosch* it is fast as hell Smile
You should add that command to the bootprocess, for example to /etc/rc.d/rc.local0
