In the past this was not an issue as the kernel called revalidate twice, thus asking the device for its write protect status twice, with write protect being disabled in the second mode sense. However, since commit 1e029397d12f ("scsi: sd: Reorganize DIF/DIX code to avoid calling revalidate twice") that is no longer the case, thus the device shows up read only. [490891.289495] sd 12:0:0:0: [sdl] Write Protect is on [490891.289497] sd 12:0:0:0: [sdl] Mode Sense: 2b 00 80 08 This does not appear to be a timing issue, as enabling the usbcore quirk USB_QUIRK_DELAY_INIT has no effect on write protect.
