From 2ab2178c3303583a0551f6b6bf4ba070afbf875f Mon Sep 17 00:00:00 2001 From: Jonathan McDowell Date: Sun, 5 Jul 2009 12:29:51 +0100 Subject: [PATCH] USB: Fix option_ms regression in 2.6.31-rc2 Commit 32ebbe7b6ad44ae9c276419710b56de6ba705303 which filters the SCSI REZERO command in option_ms based on a SCSI INQUIRY with a vendor of Option breaks my Option Icon 225 (0af0:6971). This device returns a vendor of ZCOPTION for the ZeroCD device. The following trivial patch fixes things for me.
