Alex guess was right,  I do see a new entry in usbconfig now:

ugen1.3: <USB2.0-CRW Generic> at usbus1, cfg=255 md=HOST spd=HIGH
(480Mbps) pwr=ON (500mA)

I still can't access the card, and nothing shows up in demesg, tried
plug/unplug.... no luck

Some research on USB2.0-CRW in the mailling list lead me to this:
http://lists.freebsd.org/pipermail/freebsd-usb/2012-May/011230.html

So I should add to /usr/src/sys/dev/usb/usbdevs the line

product REALTEK USB201CRW    0x0129    USB20CRW Card Reader

correct?

However I have no idea what "quirk" changes should I apply, or how to
find more info about it.

Thanks!
