My configuration:
DELL Latitude D620
Intel Centrino/ Core Duo T2400
1 GB RAM
Ubuntu 7.10 Gutsy with stock 2.6.22-14-generic kernel.

I have tried both, blacklisting ehci_hcd module, disabling it on the hub and unloading it manually. It all didn't work. Ehci_hcd module seems to be reloading automatically each time. For instance taking the card off the laptop, unloading the module, putting it back again gives following dmesg|tail output:

But when I then unplug it and replug it ehci_hcd is back on place!

I dodn't try adding the device info to the sierra drive as the card is not being recognized properly yet.
