After rebuilding and installing a new kernel from a couple of weeks ago my embedded USB flash no longer works. Working kernel was: FreeBSD 9.0-BETA1 #1 r225223M: Sat Aug 27 22:21:54 EDT 2011 Dec 1 16:40:14 edlaptop kernel: ugen3.2: <Micron Technology> at usbus3 Dec 1 16:40:14 edlaptop kernel: umass0: <Micron Technology Real SSD eUSB 16GB, class 0/0, rev 2.00/11.10, addr 2> on usbus3 Dec 1 16:40:14 edlaptop kernel: umass0: SCSI over Bulk-Only; quirks = 0x0000 Dec 1 16:40:15 edlaptop kernel: umass0:2:0:-1: Attached to scbus2 Dec 1 16:40:19 edlaptop kernel: (probe0:umass-sim0:0:0:0): TEST UNIT READY.
