Subject: [PATCH] USB: cdc-acm: quirk for Alcatel OT-I650
Date: Thu, 28 May 2009 20:33:58 +0400 [thread overview]
Message-ID: <1243528438-23040-1-git-send-email-kir@openvz.org> (raw)
This mobile phone fails to work as a modem, failing with:
cdc_acm: Zero length descriptor references
cdc_acm: probe of 1-6.1.3:1.1 failed with error -22
Tested to work fine with this patch.
