Message-Id: <1370283242-24434-2-git-send-email-marcus.overhagen@gmail.com> Date: Mon, 3 Jun 2013 20:14:01 +0200 From: Marcus Overhagen <marcus.overhagen@...il.com> To: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Cc: devel@...verdev.osuosl.org, linux-kernel@...r.kernel.org Subject: [PATCH 1/2] staging: rts5139: Fix SD card detection on Samsung NP730U3E Ultrabook The timeout detection implemented in this driver isn't very robust. Although the USB interrupt transfer was successful, the polling thread often reported timeouts because the 50ms had expired before it got scheduled, and the SD card wasn't detected. Increasing it to 100ms, as used in other places of this driver, makes it work.
