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.
