Date: Thu, 25 Sep 2014 13:56:37 +0000 (UTC) [thread overview]
Message-ID: <alpine.DEB.2.11.1409251356120.1920@localhost.localdomain> (raw)
Commit 0cce2eda19923e5e5ccc8b042dec5af87b3ffad0
USB: fix LANGID=0 regression
defaults to a langid of 0x0409 if it's not properly implemented by the
device. Explain with a higher level error message what this means.
