>Description:
When I plug my Sony cyber-shot DSC-P72, a device is created but all
access result in an IO error.

Strangly, this same device was working fine under 7.x without quirks.

dmesg:

ugen3.2: <Sony> at usbus3
umass1: <Sony Sony DSC, class 0/0, rev 1.10/4.50, addr 2> on usbus3
umass1:  RBC over CBI; quirks = 0x0008

>How-To-Repeat:

>Fix:
I add a quirks in sys/cam/scsi/scsi_da.c
