Hi, I can't get my external usb 3.0 hdd to work on usb 3.0 ports with kernels 3.11, 3.12.0, 3.13-rc1, it only works on usb 2 ports. dmesg shows, that it disconnects immediately after it is plugged in. Then it continues to connect and disconnect indefinitely: [ 2623.116141] usb 3-5: new SuperSpeed USB device number 2 using xhci_hcd [ 2623.132574] usb 3-5: New USB device found, idVendor=1058, idProduct=0740 [ 2623.132582] usb 3-5: New USB device strings: Mfr=1, Product=2, SerialNumber=5 [ 2623.132587] usb 3-5: Product: My Passport 0740 [ 2623.132591] usb 3-5: Manufacturer: Western Digital [ 2623.132595] usb 3-5: SerialNumber: 575847314139315836343531 [ 2623.133533] usb-storage 3-5:1.0: USB Mass Storage device detected [ 2623.133758] scsi7 : usb-storage 3-5:1.0 [ 2624.299678] usb 3-5: USB disconnect, device number 2 [ 2645.281554] scsi 7:0:0:0: Device offlined - not ready after error recovery [ 2645.281727] usb 3-5: Set SEL for device-initiated U1 failed.

The original bug report (with a bunch of log files) can be found under: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1254261 So I just summarize what I've tried until now: - hdd, cable and file system are fine: it works on my usb2 ports and usb3 ports of other computers (kernel 3.2, 3.11.0) - I've two exemplars of my hardware, both show the same failure - uefi bios of my system detects it correctly on usb3 - if I boot an old installation with kernel 3.2 (32bit), it works also on usb3 ports (and if I read the logs correctly, in usb 3.0 mode) - following kernel versions, don't work: 3.8, 3.11, 3.12.0, 3.13-rc1 It seems, that the problem occurs primarily with intel b85 usb 3.0 controller, maybe in combination with this particular hdd (I don't have any other usb 3.0 storage device to confirm this). lspci -v output of the concerning controller: 00:14.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB xHCI (rev 05) (prog-if 30 [XHCI]) Subsystem: ASUSTeK Computer Inc.
