+From: Oliver Neukum <oneukum@suse.de>
+Subject: fix medium presence misdetection in usb storage device 
+References: bnc#362850
+
+From reading the SCSI spec it seems that having the valid bit 0 (0x70
+checked in scsi_sense_valid) should does not invalidate the ASC or ASQ.
+[See page 37 of spc4r02.pdf].  It should only invalidate the INFORMATION
+field. Therefore remove the sense_valid check from the USB quirk.
