USB: Add reset-resume quirk for WD19's Realtek Hub
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.
