Guillaume, you can tell the SCSI core driver at boot time (or module
insertion time) and/or at runtime to
  - switch on default quirk flags,
  - add quirk flags for selected devices per name matching.

Alas I don't know of a good documention how to do either of this, and I
am not familiar enough with the procedure to explain it here.
