--- Comment #5 from Lukas Turek <8an@praha12.net> ---
I have a similar problem with D30919, for me it broke InnoDisk Nano USB stick.
In 13.0 it was detected correctly:

ugen0.7: <InnoDisk Nano USB> at usbus0
umass1 on uhub0
umass1: <InnoDisk Nano USB, class 0/0, rev 2.00/2.50, addr 6> on usbus0
umass1:  SCSI over Bulk-Only; quirks = 0xc100
umass1:15:1: Attached to scbus15
da1 at umass-sim1 bus 1 scbus15 target 0 lun 0
da1: <InnoDisk Nano USB 0250> Removable Direct Access SCSI device
da1: Serial Number 16E24A000014
da1: 40.000MB/s transfers
da1: 976MB (2000895 512 byte sectors)
da1: quirks=0x2<NO_6_BYTE>

In 13.1 the USB stick freezes and won't reconnect even after reboot, it needs
to be physically unplugged and plugged back:

usb_msc_auto_quirk: UQ_MSC_NO_GETMAXLUN set for USB mass storage device

The device doesn't actually need any dynamic quirk. In fact it's the detected
quirks that cause the device to stop responding because of this code:

        if (any_quirk) {
                /* Unconfigure device, to clear software data toggle. */
                usbd_set_config_index(udev, USB_UNCONFIG_INDEX);

                /* Need to re-enumerate the device to clear its state. */
                usbd_req_re_enumerate(udev, NULL);
                return (USB_ERR_STALLED);
        }

When I commented it out, the USB stick worked correctly:

usb_msc_auto_quirk: UQ_MSC_NO_GETMAXLUN set for USB mass storage device
InnoDisk Nano USB (0x196d:0x0201)
usb_msc_auto_quirk: UQ_MSC_NO_PREVENT_ALLOW set for USB mass storage device
