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 =3D -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 =3D -32) After analysis, xhci try to set link in U3 and returns an error. Using snps,dis_u3_susphy_quirk fix this issue.
