 I've just tried on a NetBSD-5.99.8/amd64 from March 23 -- problem
 still exists.
 
 On plugging it in, dmesg contains:
 umass0 at uhub2 port 2 configuration 1 interface 0
 umass0: Meizu   Electronics MiniPlayer, rev 2.00/1.00, addr 5
 umass0: using SCSI over Bulk-Only
 scsibus0 at umass0: 2 targets, 1 lun per target
 sd0 at scsibus0 target 0 lun 0: <Meizu, MiniPlayer, 1.00> disk removable
 sd0: 7820 MB, 7840 cyl, 16 head, 32 sec, 512 bytes/sect x 16015360 sectors
 
 When unmounting, I immediately get:
 umass0: Phase Error, residue = 0
 and about 10 minutes later:
 sd0: cache synchronization failed
 
 Then it's not mounted any longer and I can unplug it without any
 (obvious) problems.
 
 I expect it to be a USB bug and not a file system one...
