Hi Mathias, Greg I am working on ARM STi platform, since v4.10-rc1, when booting B2260 or B2120 STi boards platform with nothing plugged on USB3 connector, i observed the following kernel logs : .... [ 801.953836] usb usb6-port1: Cannot enable. Maybe the USB cable is bad? [ 801.960455] xhci-hcd xhci-hcd.0.auto: Cannot set link state. [ 801.966611] usb usb6-port1: cannot disable (err = -32) [ 806.083772] usb usb6-port1: Cannot enable. Maybe the USB cable is bad? [ 806.090370] xhci-hcd xhci-hcd.0.auto: Cannot set link state. [ 806.096494] usb usb6-port1: cannot disable (err = -32) [ 810.208766] usb usb6-port1: Cannot enable. Maybe the USB cable is bad? [ 810.215374] xhci-hcd xhci-hcd.0.auto: Cannot set link state. [ 810.221478] usb usb6-port1: cannot disable (err = -32) [ 814.333767] usb usb6-port1: Cannot enable. Maybe the USB cable is bad? [ 814.340364] xhci-hcd xhci-hcd.0.auto: Cannot set link state. ..... Another interesting thing is even if i plugged a device (a mass storage device in my case) on the USB3 connector, the above logs continue to appear. This is due to commit 37be66767e3ca "usb: hub: Fix auto-remount of safely removed or ejected USB-3 devices". I don't know if STi platforms are the only impacted by this issue. On v4.9 everything was ok.
