Или следовало дать права не на %systemroot%\inf\usbstor.inf, а на \SystemRoot\WinSxS\x86_usbstor.inf ?
В общем, и там все права дал, но всё равно каменный цветок не выходит.

Теперь как-то странно пишет. Сначала, что некий пакет вообще not applicable, и потому установлен не будет, а в процессе выключения лезет инсталлировать драйвер из usbstor.inf, после чего вываливается с той же ошибкой "доступ запрещен".
причем, усбстор берет той же версии \x86_usbstor.inf_31bf3856ad364e35_6.1.7601.19144_none_4a6d13b5f62dc6c7 что и в логе выше, и доступ к ним полный и у админов и у системы и у трастед инсталлер.
