Subject: [PATCH] Microsoft Sufrace Dock USB Ethernet
Date: Mon, 16 Jun 2014 18:26:27 +0200 [thread overview]
Message-ID: <13982460-3633-4BA4-A466-31E5A27C2F41@exactcode.com> (raw)
Currently the cdc_ether driver is matched for the Microsoft Surface Dock USB port,
however it does not work and will not send/receive any packets. Instead using the
r8152 driver explicitly appears to work fine for me, so far.
