I do get these errors in dmesg now though, which also weren't in 3.17: [ 0.881967] usb: failed to peer 1-9-port1 and 2-5-port1 by location (1-9-port1:none) (2-5-port1:usb1-port11) [ 0.881968] usb 1-9-port1: failed to peer to 2-5-port1 (-16) [ 0.881969] usb: port power management may be unreliable [ 0.881993] usb: failed to peer 1-9-port2 and 2-5-port2 by location (1-9-port2:none) (2-5-port2:usb1-port12) [ 0.881994] usb 1-9-port2: failed to peer to 2-5-port2 (-16) [ 0.882015] usb: failed to peer 1-9-port3 and 2-5-port3 by location (1-9-port3:none) (2-5-port3:usb1-port13) [ 0.882016] usb 1-9-port3: failed to peer to 2-5-port3 (-16) [ 0.882037] usb: failed to peer 1-9-port4 and 2-5-port4 by location (1-9-port4:none) (2-5-port4:usb1-port14) [ 0.882038] usb 1-9-port4: failed to peer to 2-5-port4 (-16) Full dmesg is attached to this bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1183289 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
