 Hi!
 
 Please reopen this PR. I can serve with the requested feedback.
 
 Note that I have a Pentax Optio S40 but the behaviour shown is the same
 with this device (both the original, problematic behaviour and the one
 shown after applying the fix).
 
 If I take out the USB_VENDOR_ASAHIOPTICAL entry from umass_devdescrs,
 the behaviour is the same as with the provided fix: there are "phase
 error" messages, but the da0 device works aptly. Here is the exact
 batch of kernel messages after plugging the camera in:
 
 umass0: PENTAX product 0x0015, rev 1.10/0.00, addr 3
 da0 at umass-sim0 bus 0 target 0 lun 0
 da0: <PENTAX DIGITAL_CAMERA 1.00> Removable Direct Access SCSI-0 device 
 da0: 1.000MB/s transfers
 da0: 483MB (990976 512 byte sectors: 64H 32S/T 483C)
 umass0: Phase Error, residue = 0
 (da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0
 umass0: Phase Error, residue = 0
 (da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0
 umass0: Phase Error, residue = 0
 (da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0
 umass0: Phase Error, residue = 0
 (da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0
 umass0: Phase Error, residue = 0
 (da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0
 umass0: Phase Error, residue = 0
 (da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0
 
 For my system, kern.osreldate is 700000, but I don't think that this would have
 too much importance in this case.

 Csaba
