The problem is like this: (if you remember I using FX2 device):
UHCI part works fine. EHCI does not. here is part of the log:
------------------------------------------------------------------------
hub.c: USB new device connect on bus4/4, assigned device number 2
usb.c: USB device not responding, giving up (error=-71)
hub.c: USB new device connect on bus4/4, assigned device number 3
usb.c: USB device 3 (vend/prod 0x4b4/0x8613) is not claimed by any active
driver
.
usb.c: USB disconnect on device 3
hub.c: USB new device connect on bus4/4, assigned device number 4
usb.c: USB device not responding, giving up (error=-71)
hub.c: USB new device connect on bus4/4, assigned device number 5

hub.c: USB new device connect on bus4/4, assigned device number 6
usb.c: USB device 6 (vend/prod 0x4b4/0x8613) is not claimed by any active

usb.c: USB disconnect on device 6

usb.c: USB device not responding, giving up (error=-71)
hub.c: USB new device connect on bus4/4, assigned device number 8

So, basically, it connects fine to UHCI part and then fails to switch over
to EHCI.
I am not using any hubs, aside from the one in the card. Also the card
looks a quite similar to the one on VIA's website, but many capacitors are
missing (for example the ones near the ports). I am suspecting this might
be a power issue of some sort - my device has about 11 microFarad before
voltage regulator. Or, perhaps, they removed the capacitors and counted on
a longer delay between power-on of the port and trying to access the
device.. Can USB driver control this ?
thanks
