i've used the following commanda to add the quirks:

usbconfig add_dev_quirk_vplh 0x04e8 0x6720 0x0100 0x0100 UQ_MSC_NO_TEST_UNIT_READY
usbconfig add_dev_quirk_vplh 0x04e8 0x6720 0x0100 0x0100 UQ_MSC_NO_SYNC_CACHE

`usbconfig dump_device_quirks|grep 0x04e8` says:

VID=0x04e8 PID=0x5092 REVLO=0x0000 REVHI=0xffff QUIRK=UQ_MSC_NO_SYNC_CACHE
VID=0x04e8 PID=0x6720 REVLO=0x0100 REVHI=0x0100 QUIRK=UQ_MSC_NO_SYNC_CACHE
VID=0x04e8 PID=0x6720 REVLO=0x0100 REVHI=0x0100 QUIRK=UQ_MSC_NO_TEST_UNIT_READY

still no difference. as soon as i attach the device it crashes and reboots
itsself (the mobile). sometimes it doesn't, however when i read data from it it
then crashes instantly.

here are the device details:

ugen3.3: <SGH-i550 Samsung> at usbus3, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON


 Configuration index 0

    bLength = 0x0009 
    bDescriptorType = 0x0002 
    wTotalLength = 0x0020 
    bNumInterfaces = 0x0001 
    bConfigurationValue = 0x0001 
    iConfiguration = 0x0004  <Bulk transfer method configuration>
    bmAttributes = 0x00e0 
    bMaxPower = 0x0032 

    Interface 0
      bLength = 0x0009 
      bDescriptorType = 0x0004 
      bInterfaceNumber = 0x0000 
      bAlternateSetting = 0x0000 
      bNumEndpoints = 0x0002 
      bInterfaceClass = 0x0008 
      bInterfaceSubClass = 0x0006 
      bInterfaceProtocol = 0x0050 
      iInterface = 0x0006  <USB Mass Storage Interface>

     Endpoint 0
        bLength = 0x0007 
        bDescriptorType = 0x0005 
        bEndpointAddress = 0x0081  <IN>
        bmAttributes = 0x0002  <BULK>
        wMaxPacketSize = 0x0200 
        bInterval = 0x00ff 
        bRefresh = 0x0000 
        bSynchAddress = 0x0000 

     Endpoint 1
        bLength = 0x0007 
        bDescriptorType = 0x0005 
        bEndpointAddress = 0x0001  <OUT>
        bmAttributes = 0x0002  <BULK>
        wMaxPacketSize = 0x0200 
        bInterval = 0x00ff 
        bRefresh = 0x0000 
        bSynchAddress = 0x0000 

the output of `otaku% kldstat -v|grep usb` is:

72 usbus/uhub
71 uhub/usb_linux
69 uss820/usbus
68 at91_udp/usbus
67 ehci/usbus
66 uhci/usbus
65 ohci/usbus

however `kldload usb_quirk` fails with EEXIST.

cheers.
