Message-ID: <20121009193509.GA14107@xanatos> Date: Tue, 9 Oct 2012 12:35:09 -0700 From: Sarah Sharp <sarah.a.sharp@...ux.intel.com> To: WANG Siyuan <wangsiyuanbuaa@...il.com> Cc: Daniel Mack <zonque@...il.com>, linux-kernel@...r.kernel.org, linux-usb@...r.kernel.org Subject: Re: usb 3.0 hard drive doesn't work This is probably a known issue. Other Western Digital hard drives had issues with the Link PM feature that went into 3.5. Can you please test with this branch: git clone git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci.git -b for-usb-linus-pending In particular, I think this patch will help you, if you want to just try that: http://git.kernel.org/?p=linux/kernel/git/sarah/xhci.git;a=commit;h=ae8963adb4ad8c5f2a89ca1d99fb7bb721e7599f Sarah Sharp On Tue, Oct 09, 2012 at 09:51:55AM +0800, WANG Siyuan wrote: > hi, Daniel > my usb 3.0 hard drive doesn't have external power. this is a "western > digital" usb hard drive: WDBACY5000AWT > here is a Product Specifications: > http://www.wdc.com/wdproducts/library/AAG/ENG/4178-705131.pdf > > i start my laptop with ubuntu, the usb3.0 port could use the usb3.0 > hard drive. but the write speed is only 50MB/s (test with dd) > but archlinux cannot recognize the hard drive. > > thank you for replaying. > > On Mon, Oct 8, 2012 at 5:31 AM, Daniel Mack <zonque@...il.com> wrote: > > (cc linux-usb) > > > > On 07.10.2012 10:48, 王思源 wrote: > >> hi, > >> i have a usb 3.0 hard drive and a laptop with usb 3.0 port. > >> when the hard drive is connected to the usb 3.0 port, the drive could > >> not be found. > >> the dmesg output is listed below. > >> additinal info: > >> 1) the usb 3.0 hard drive can be found when connected to usb 2.0 port. > >> 2) the usb 2.0 hard drive can be found when connected to usb 3.0 port. > >> 3) mouse works when connected to the usb 3.0 port. > >> 4) it is archlinux and kernel version is 3.5.5-1-ARCH > >> it seems that it is not the linux driver's problem, because the mouse > >> could work and the hard drive is found due to the dmesg. > >> is this a bug? > >> would someone help me? > >> thank you! > >> > >> dmesg out put when usb 3.0 hard drive is conneted to usb 3.0 port: > >> [ 646.077385] usb 2-2: new SuperSpeed USB device number 2 using xhci_hcd > >> [ 646.171319] usbcore: registered new interface driver uas > >> [ 646.175313] Initializing USB Mass Storage driver... > >> [ 646.175501] scsi4 : usb-storage 2-2:1.0 > >> [ 646.175665] usbcore: registered new interface driver usb-storage > >> [ 646.175667] USB Mass Storage support registered. > >> [ 657.149403] scsi 4:0:0:0: Direct-Access WD My Passport > >> 0730 1016 PQ: 0 ANSI: 6 > >> [ 657.149974] sd 4:0:0:0: [sdb] 976707584 512-byte logical blocks: > >> (500 GB/465 GiB) > >> [ 657.150223] sd 4:0:0:0: [sdb] Write Protect is off > >> [ 657.150232] sd 4:0:0:0: [sdb] Mode Sense: 47 00 10 08 > >> [ 657.150456] sd 4:0:0:0: [sdb] No Caching mode page present > >> [ 657.150462] sd 4:0:0:0: [sdb] Assuming drive cache: write through > >> [ 657.151436] sd 4:0:0:0: [sdb] No Caching mode page present > >> [ 657.151440] sd 4:0:0:0: [sdb] Assuming drive cache: write through > >> [ 657.159907] sdb: sdb1 > >> [ 657.160852] sd 4:0:0:0: [sdb] No Caching mode page present > >> [ 657.160858] sd 4:0:0:0: [sdb] Assuming drive cache: write through > >> [ 657.160861] sd 4:0:0:0: [sdb] Attached SCSI disk > >> [ 657.268875] usb 2-2: Device not responding to set address. > >> [ 657.471456] usb 2-2: Device not responding to set address. > >> [ 657.674211] usb 2-2: device not accepting address 2, error -71 > >> [ 657.780745] usb 2-2: Device not responding to set address. > >> [ 657.983519] usb 2-2: Device not responding to set address. > >> [ 658.186214] usb 2-2: device not accepting address 2, error -71 > >> [ 658.292717] usb 2-2: Device not responding to set address. > >> [ 658.495537] usb 2-2: Device not responding to set address. > > > > From the logs, this smells like a power supply problem.
