  Here is the output of "usbconfig dump_device_desc" relevant to the device:

ugen3.2: <YP-U3 Samsung Electronics> at usbus3, cfg=0 md=HOST spd=HIGH 
(480Mbps) pwr=ON

   bLength = 0x0012
   bDescriptorType = 0x0001
   bcdUSB = 0x0200
   bDeviceClass = 0x0000
   bDeviceSubClass = 0x0000
   bDeviceProtocol = 0x0000
   bMaxPacketSize0 = 0x0040
   idVendor = 0x04e8
   idProduct = 0x507c
   bcdDevice = 0x0220
   iManufacturer = 0x0001 <Samsung Electronics>
   iProduct = 0x0002 <YP-U3>
   iSerialNumber = 0x0003 <CEFBF7F26DFF0000>
   bNumConfigurations = 0x0001

It still doesn't work out of the box on any version of FreeBSD, but I am 
running CURRENT now, so the following makes it work:

usbconfig -d 3.2 add_quirk UQ_MSC_NO_INQUIRY
usbconfig -d 3.2 add_quirk UQ_MSC_NO_SYNC_CACHE
usbconfig -d 3.2 reset
usbconfig -d 3.2 reset
