It crashes on synchronize cache:

Try adding this quirk:

usbconfig -d ugen1.3 add_quirk UQ_MSC_NO_SYNC_CACHE

Then re-plug the device.

--HPS

Could this be done before device attach? Trouble is, after synchronize
crashes, USB firmware crashes as well. This means there is basically no
ugen1.3 device anymore, so doing this command just tells (after some
delay)

Adding quirk 'UQ_MSC_NO_SYNC_CACHE' failed, continuing.

Next I must reset the board, but before I am able to do anything, it
crashes again.

Hi,

man usb_quirk

     To install a quirk at boot time, place one or several lines like the
     following in loader.conf(5):

hw.usb.quirk.0="0x1514 0x0001 0 0xffff UQ_MSC_NO_SYNC_CACHE"
hw.usb.quirk.0="0x1514 0x0001 0 0xffff UQ_NO_STRINGS"

--HPS
