I have tested this time with two PSC 1610 printers, and two SD cards,
the same bug occured without the patch.
And is fixed with your new patch. Good work !

The bug however did not occur with a microSD card in a SD adaptator ?!

But it fixes only two models.
Do you think other devices (hp or not) can be impacted ?
There are hundreds of models with card readers only for hp :

Will this be possible to use "LAST_SECTOR_BUG" quirk for testing without
recompiling a kernel ?
