| |
2.6.30-stable review patch. If anyone has any objections, please let us know.
------------------
From: Giacomo Lozito <james@develia.org>
commit 7a777919bbeec3eac1d7904a728a60e9c2bb9c67 upstream.
Requests to get max LUN, for certain USB storage devices, require a longer timeout before a correct reply is returned. This happens for a Realtek USB Card Reader (0bda:0152), which has a max LUN of 3 but is set to 0, thus losing functionality, because of the timeout occurring too quickly.
Raising the timeout value fixes the issue and might help other devices to return a correct max LUN value as well.
