Subject: [PATCH 5.12 13/17] USB: Add reset-resume quirk for WD19s Realtek Hub
Date: Wed, 5 May 2021 14:06:08 +0200 [thread overview]
Message-ID: <20210505112325.388580102@linuxfoundation.org> (raw)
In-Reply-To: <20210505112324.956720416@linuxfoundation.org>
From: Chris Chiu <chris.chiu@canonical.com>
commit ca91fd8c7643d93bfc18a6fec1a0d3972a46a18a upstream.
Realtek Hub (0bda:5487) in Dell Dock WD19 sometimes fails to work
after the system resumes from suspend with remote wakeup enabled
device connected:
[ 1947.640907] hub 5-2.3:1.0: hub_ext_port_status failed (err = -71)
[ 1947.641208] usb 5-2.3-port5: cannot disable (err = -71)
[ 1947.641401] hub 5-2.3:1.0: hub_ext_port_status failed (err = -71)
[ 1947.641450] usb 5-2.3-port4: cannot reset (err = -71)
Information of this hub:
T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 10 Spd=480 MxCh= 5
D: Ver= 2.10 Cls=09(hub ) Sub=00 Prot=02 MxPS=64 #Cfgs= 1
P: Vendor=0bda ProdID=5487 Rev= 1.47
S: Manufacturer=Dell Inc.
S: Product=Dell dock
C:* #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr= 0mA
I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=01 Driver=hub
E: Ad=81(I) Atr=03(Int.) MxPS= 1 Ivl=256ms
I:* If#= 0 Alt= 1 #EPs= 1 Cls=09(hub ) Sub=00 Prot=02 Driver=hub
E: Ad=81(I) Atr=03(Int.) MxPS= 1 Ivl=256ms
The failure results from the ETIMEDOUT by chance when turning on
the suspend feature for the specified port of the hub. The port
seems to be in an unknown state so the hub_activate during resume
fails the hub_port_status, then the hub will fail to work.
The quirky hub needs the reset-resume quirk to function correctly.
