From ae38c78a03e1b77ad45248fcf097e4568e740209 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Fri, 1 Oct 2010 14:20:10 -0700 Subject: usb-storage: add new no_read_disc_info quirk Appotech ax3003 (the larger brother of the ax203) based devices are even more buggy then the ax203. They will go of into lala land when ever they see a READ_DISC_INFO scsi command. So add a new US_FL which tells the scsi sr driver to not issue any READ_DISC_INFO scsi commands.
