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.
