 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
