Troubleshooting USB enclosure speeds?

      Hi guys,

      I have a USB HD enclosure based on the PL3507 chipset. Both my NSLU2
      and my windows laptop detect this as a USB2.0 device but run it only
      at 1.1 speeds. My NSLU2 is running OpenSlug and if I output
      /proc/bus/usb/devices to the screen I see:

      T: Bus=03 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
      D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
      ...

      You can see from the first line that Spd=12 (ie 12mbit) yet on the 2nd
      line Ver= 2.00 (ie USB2.0).

      I've tried flashing to the latest PL3507 firmware, replacing my USB
      cable to one that is "certified" for USB2.0 - no difference.

      Does anyone else here have any suggestions on what could cause this
      device to run slow?

      Failing that, can anybody recommend me a quality USB enclose that
      definitely run at USB 2.0 speeds on the NSLU2?

      Thanks for any advice...

      Interesting message! I m having problems with my NSLU2 (or more precisely, my USB enclosure?) and maybe you have found my problem as well! Here are my T and D

        Interesting message!

        I'm having problems with my NSLU2 (or more precisely, my USB enclosure?) and
        maybe you have found my problem as well!

        Here are my T and D lines from /proc/bus/usb/devices:
        T: Bus=03 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2
        D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1

        From what you're saying it looks like my USB enclosure is running at
        USB 1.2speed (?). Maybe that's why it is INCREDIBLY slow to use over
        the network?
        (via the NSLU2)

        Hopefully you can get this figured and hopefully the fix will help me as
        well!

          Here is some more information about my USB enclosure...

          My USB enclosure is connected directly to my NSLU2 which is connected
          to my network (standard 100 Mbps LAN).

          The enclosure I have is the Ultra ULT31310 (see link below for more details).

          The product information page says it supports USB 2.0.

            Hi John,

            It definitely looks from what you posted that your USB device is USB1.1 (ie
            Ver= 1.10), whereas in my case my device is actually detected as USB2.0, but
            still running at USB1.1 speeds.

            The /proc/bus/usb/devices file contains two entries, in addition to any USB
            devices plugged in. These represent the 'USB Bus'. You will actually see
            two of these, one for High speed/2.0 and one for low speed 1.1. (From what
            I understand, these are just 'logical' buses, they've got nothing to do with
            the physical ports on your nslu2).

            Is it possible you're looking at the wrong entry? Check out the
            Vendor/Product lines to be sure...

            Cheers,
            Larz

              HMm ok. So you have a couple of entries for USB OHCI Root Hub - these are your USB bus entries I think. Your USB enclosure is probably this entry: T: Bus=01

                HMm ok. So you have a couple of entries for USB OHCI Root Hub - these are
                your USB bus entries I think.

                Your USB enclosure is probably this entry:
                T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 2 Spd=480 MxCh= 0
                D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
                P: Vendor=067b ProdID=3507 Rev= 0.01
                S: Manufacturer=Prolific Technology Inc.
                S: Product=ATAPI-6 Bridge Controller

                Prolific are a manufacturer of USB enclosure chipsets. Looks like you've
                got the PL3507, which is pretty common. But according to the above, yours
                (unlike mine!) is being picked up as a USB2.0 device and running at
                480mbit. So I think you're speed problems may lie elsewhere. You might
                want to do some tests copying large files around on your drive to confirm
                whether or not the HD access speeds are the issue?

                Interestingly, my USB enclosure is based on the same chipset as yours, but
                still only runs at 12mbit :(

                T: Bus=03 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
                D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
                P: Vendor=067b ProdID=3507 Rev= 1.00
                S: Manufacturer=Prolific Technology Inc.
                S: Product=Mass Storage Device

                I'm thinking I'm going to have to buy a new enclosure.

                Cheers,
                Lars

                  Thanks for the information!!

                  How can I test to make sure the HDD access speed isn't my problem? Do I
                  need to copy a file locally and somehow monitor the transfer rate? ...or
                  should I download it using FTP on one of my machines connected to my LAN?

                  Thanks! Good luck with your enclosure!

                    I basically time how long it takes to copy say a 5MB file (eg: cp my5mbFile my5mbFileCopy). On my slug with my enclosure running at 12mbit, this takes about

                      I basically time how long it takes to copy say a 5MB file (eg: cp my5mbFile
                      my5mbFileCopy). On my slug with my enclosure running at 12mbit, this takes
                      about 25 seconds (!!!), wheras I think this should take only about 2 seconds
                      (or less) at USB2.0 speeds.

                      If that's working, you might want to try some similar tests with FTP to and
                      from your nslu2 vs between other machines on your LAN to try and narrow down
                      where the bottleneck is. Perhaps there are more sophisticated ways to
                      profile this, but I'm not aware of them (I'd be interested to hear anyone
                      else's suggestions - or any on how I might be able to force my enclosure to
                      be used at full speed!)

                      Cheers,
                      Larz

                      Thanks for the replies! According to the FlashDriveLifespanSurvey article, I should execute this command on my NSLU2: $ dd if=/dev/zero of=/file/on/drive

                        Thanks for the replies!

                        According to the FlashDriveLifespanSurvey article, I should execute this
                        command on my NSLU2:

                        $ dd if=/dev/zero of=/file/on/drive bs=8192 count=1024 conv=fsync

                        However, when I try to do that it says "dd: invalid converion 'fsync'"

                        However, here are some other commands I've tried (and their results):


                        # hdparm -T /dev/sda1
                        /dev/sda1:
                        Timing cached reads: 152 MB in 2.02 seconds = 75.25 MB/sec

                        # hdparm -t /dev/sda1
                        /dev/sda1:
                        Timing buffered disk reads: 24 MB in 3.04 seconds = 7.89 MB/sec

                        How do those results look? I have no idea what I'm actually looking for...
                        (eg. what the numbers should be)
