Please explain more fully.  What SCSI driver are you talking about?  
Where is the flag getting added incorrectly?  What USB drive is getting
broken, and how?

If there's a bug in a SCSI driver, why don't you report it and get it
fixed instead of trying to create a workaround in just one host 
controller driver?
