In fact I successfully done it working with :

attach 100 {
         device-name "uhid[0-9]+"; 

         match "vendor"  "0x046e";
         match "product" "0x55a5";
         action "/usr/bin/usbhidaction -f $device-name -c 

I saw the vendor and product id using usbconfig show_ifdrv :

ugen0.3.1: uhid0: <BTC USB Multimedia Keyboard, class 0/0, rev 
1.10/1.20, addr 3>
