Subject: [PATCH v2] usb: quirks: Add no-lpm quirk for Moshi USB to Ethernet Adapter
Date: Tue,  8 Aug 2017 14:32:54 +0800	[thread overview]
Message-ID: <20170808063254.6487-1-kai.heng.feng@canonical.com> (raw)

Moshi USB to Ethernet Adapter internally uses a Genesys Logic hub to
connect to Realtek r8153.

The Realtek r8153 ethernet does not work on the internal hub, no-lpm quirk
can make it work.

Since another r8153 dongle at my hand does not have the issue, so add
the quirk to the hub instead.

Signed-off-by: Kai-Heng Feng <kai.heng.feng@canonical.com>

v2: Clarify that the adapter uses a hub internally.
