>Description:
This problem seems to be solved before (kern/60389). There is a quirk there for SL11R, already implemented in umass.c. It just does not work on this device.
pluging the USB CD-RW gives this messages:

I UNSUCCESFULY tried to hack /usr/src/sys/cam/scsi/scsi_da.c adding (just to see whether it goes... this is NOT a patch):
{
/*
* Q-lity CD-RW ECW-043, Quanta Storage INC.
* Chipset ScanLogic SL11R
*/
{T_DIRECT, SIP_MEDIA_REMOVABLE, "*" , "*", "*"},
/*quirks*/ DA_Q_NO_SYNC_CACHE|DA_Q_NO_PREVENT
},
may be another quirk is neede in umass.c.
I can work on it with some clues... unfortunatelly scanlogic removed from their website technical info for this chipset.
Thanks
>How-To-Repeat:
you need a Q-Lity ECW-043 CD-RW USB (Quanta Storage INC.) or maybe other device using ScanLogic SL11R chipset
