Something is wrong there. I think this should not happen:
kernel: (da0:umass-sim0:0:0:0): CAM status: SCSI Status Error
kernel: (da0:umass-sim0:0:0:0): SCSI status: Check Condition
kernel: (da0:umass-sim0:0:0:0): SCSI sense: No sense data present
Two questions: 1) what originally caused these errors and 2) why "No
sense data present". I am not sure whether it is device problem or umass
or both. I can't reproduce it with devices I have. Could you also show
your old error messages (preferably verbose) to compare?
One more interesting aspect: during probe device properly report its
size. On first open it works also, just reporting suspicious errors on
PREVENT ALLOW MEDIUM REMOVAL and SYNCHRONIZE CACHE(10). But on second
open READ CAPACITY(10) is no longer working. I suspect something happens
to the device on first open.
