It should be cleared by fetching sense command. As I was assured by 
several people, it is SIM (controller driver, umass) obligation to fetch 
sense and respectively clear it when error detected. But not sure what 
should umass do if this device STALLs. May be should try to do it also. 
So far I haven't see any properly fetched sense from it in provided logs.
