Created attachment 115811 [details] dmesg part about failing connection attempts Originally filed under: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1254261 On a fresh saucey installation (kernel 3.11), I can not use my external usb 3.0 hdd on usb 3.0 ports, it only works on usb 2 ports. kernel log shows, that it disconnects immediately after it is plugged in. Then it continues to connect and disconnect indefinitely (q.v. attached dmesg log): [ 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 same hw combination works with kernel 3.2 in precise, but not with 3.8 (see attachments in the linked report). I even tried 3.12 coming with trusty and the 3.13-rc1 ubuntu mainline kernel, but got the same log messages as with 3.11.

As a last resort I upgraded the bios/uefi of the mainboard (B85M-G BIOS 0410 -> B85M-G BIOS 0703) and now it works. Funny though, that 3.2 managed to circumvent whatever the bios messed up. Anyway, sorry for the noise.
