FreeBSD 10.0 didn't support anymore Kingston DT 101 G2 (I belevied that 
9.1 supported it, but didn't have 9.1 for checking).
>How-To-Repeat:
Error message when USB key inserted:

>Fix:
Apply the patch attached.
Note: I've try with "DA_Q_NO_SYNC_CACHE" only first but it didn't work, 
then I've try with "DA_Q_NO_PREVENT" in place, but it still didn't work. 
At last I've used both "DA_Q_NO_SYNC_CACHE|DA_Q_NO_PREVENT" (without 
idea of what I'm doing, I've just read the other quirks)
 and It's 
worked :-)

Patch attached with submission follows:
