| Subject: usb-storage: Add compatibility quirk flags for iODD 2531/2541 |
| |
| From: James Buren <braewoods+lkml@braewoods.net> |
| |
| commit 05c8f1b67e67dcd786ae3fe44492bbc617b4bd12 upstream. |
| |
| These drive enclosures have firmware bugs that make it impossible to mount |
| a new virtual ISO image after Linux ejects the old one if the device is |
| locked by Linux. Windows bypasses this problem by the fact that they do |
| not lock the device. Add a quirk to disable device locking for these |
| drive enclosures. |
