Hi Xenia, thank you. I tested this patch on 3.11 kernel and the messages don't appear anymore upon LPM-capable device disconnect (tested with ASMedia AS2105 devices). Not much to show here, there is just no error/warning related to LPM while handling these devices. Probably better test is with Prolific-based device for which I get during connect: [ 999.906164] usb 4-2.1: new SuperSpeed USB device number 20 using xhci_hcd [ 999.928475] usb 4-2.1: New USB device found, idVendor=067b, idProduct=2773 [ 999.928488] usb 4-2.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 999.928495] usb 4-2.1: Product: USB-SATA Bridge [ 999.928501] usb 4-2.1: Manufacturer: Prolific Technology Inc.

[ 999.931681] usb 4-2.1: Set SEL for device-initiated U2 failed. and during disconnect kernel is also quiet and doesn't complain anymore about the LPM of already disconnected device: [ 1582.039612] usb 4-2.1: USB disconnect, device number 20 I think your patch works correctly and has shutdown the bogus/annoying message. ;-) Thank you.
