[ Follow-up to my mail ]

After looking a bit into man page, I found it is actually easy to do it
without reboot (which is important for my main workstation, otherwise
I'd have to reopen quite a number of various windows...). Also, it
looks like some bug in loader makes it not possible to add more than
one quirk on boot time, which I can 'fix' from shell:

kldload usb_quirk
usbconfig add_dev_quirk_vplh 0x1514 0x0001 0 0xffff UQ_NO_STRINGS
usbconfig add_dev_quirk_vplh 0x1514 0x0001 0 0xffff UQ_MSC_NO_SYNC_CACHE

Now I can get expected info from 'usbconfig -d ugen1.3 dump_all_desc'
command:

ugen1.3: <vendor 0x1514 product 0x0001> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (100mA)

        bRefresh = 0x0000 
        bSynchAddress = 0x0000

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

and 'usbconfig show_ifdrv' relevant lines are

ugen1.3: <vendor 0x1514 product 0x0001> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (100mA)
ugen1.3.0: umass0: <vendor 0x1514 product 0x0001, class 0/0, rev 2.00/30.00, addr 3>

Relevant lines in console log/dmesg:

ugen1.3: <vendor 0x1514 product 0x0001> at usbus1
umass0 on uhub3
umass0: <vendor 0x1514 product 0x0001, class 0/0, rev 2.00/30.00, addr 3 on usbus1

da0: 40.000MB/s transfers
da0: 7457MB (15273600 512 byte sectors)
da0: quirks=0x2<NO_6_BYTE>

Now, 'gpart show da0' displays expected partitioning data, I can
'mount_msdosfs /dev/da0p2 /media' and access files there as needed.

Thanks for really valuable help, highly appreciated.
