Sony Vaio PCG FRV series and Memory Card Slot v5

[Patrick Tracanelli]

Hello,

How can I configure access the memory card onboard device slot at Sony 
Vaio PCG FRV? I see a number of people can do it usually v4.0 device, 
but I just did not find anyone using it on a Sony Vaio PCG FRV series; 
It is a v5.0 slot, while in usbbdevs I could find the entries related to 
v4.0 and v4.1; It's a 5.3-STABLE system. usbdevs -dv returns nothing; 
Sony's comentation call it "WB" Memory Card Slot; Any idea on what could 
be done?

If I can send any helpfull output from any command/dump please let me 
know. Thanks.
