my laptop comes with an internal Realtek card reader ( vendor=0x0bda, 
product=0x0139 )

It is not recognized by udevd.

The bInterface class is 255, which I think is wrong ( should be 8 for 
mass storage device, i think )

Right now the kern does not assign this device to usb-storage.
The realtek driver is nice, but the product id of 0x0138 does not match 
this productid 0f 0x0139.

How are the udev hooks supposed to work to rename the bInterface class 
from vendor specific to mass storage/realtek driver?
