Not because the condition is disqualifying, but merely because usb-persist was never given = the capability of handling it. In theory this capability could be added. But would it be worthwhile? How common are systems with this hardware bug? --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
