az lspci kimeneteben latszik, hogy a chipset mire kepes:
02:04.0 USB Controller: NEC Corporation USB (rev 41) (prog-if 10
[OHCI])
Subsystem: Asustek Computer, Inc. PCI-USB2 (OHCI subsystem)
Flags: bus master, medium devsel, latency 32, IRQ 255
Memory at ed800000 (32-bit, non-prefetchable) [disabled]
[size=4K]
Capabilities: <access denied>

Aztan ha radugsz egy eszkozt az usb-re akkor latszik az adott bus-on
milyen eszkoz van (Ver= sorok a relevansak, a bus=01 a hdd):

Tehat a bus es a radugott eszkoz megmondja, hogy mire kepes, ezek
alapjan valasztja ki a kernel, hogy melyik usb host-tal kezeli. Nalam
az volt a baj, hogy csak egy bus tudja az usb2.0-at (nem mai gyerek
az alaplapom), raadasul ez a bus nem volt kihozva a gep
csatlakozoira, csak az alaplapon arvalkodott uresen.

Probaltam, de a fentiek alapjan ez nem segithet.
