Thinkpad 8 USB 3.0 port = getting USB 2.0 speeds

I have (2) Thinkpad 8 devices (one for work and one for home) and both are NOT getting USB 3.0 connectivity when connected to a USB 3.0 device. 
under device info (in the Charms menu), it says
"device can perform faster when connected to USB 3.0". 
That means for whatever reason, the system is NOT seeing a USB 3.0 connected and is dumbing the speed down to USB 2.0.  That is a big big big deal.  At least for me. 
I'm not sure what the solve is here, but I have tried reinstalling windows (fail), downloading drivers from the Intel site (failed to work for me) and have tried uninstalling the USB drivers and having windows reinstall the drivers (failed for me). 
I looked at the USB tree viewer and it shows my device's bus speed is USB 2.0 (the device itself is certified USB 3.0 and I have checked the device in another laptop with USB 3.0 and it works like it should). 
I am UNABLE to get speeds about 30 - 35 mb/s which is the upper limit of the USB 2.0 spec. 
Is this a warranty issue?  I think so. 
Can anyone from Lenovo help???
Solved!

Mark,
Can you kindly take a look at my post here:
https://forums.lenovo.com/t5/ThinkPad-slate-tablets/Thinkpad-8-USB-3-0-port-getting-USB-2-0-speeds/t...
This is a very big discovery and I think it affects ALL TP8 owners.  I have confirmed with at least ONE more person in another forum that they too are NOT seeing any USB 3.0 connectivity.  I own two of these TP8s and I am not happy that the tablets do not support USB 3.0 straight out of the box.  It appears to be a hardware issue (or maybe it's just firmware).  I have reinstalled the drivers multiple times but to no avail.  The drivers appear to be correct.  It just will NOT connect at USB 3.0 speeds due to the HOST (i.e. the tablet) not supporting USB 3.0

  • Using Thinkpad Trackpoint USB Keyboard with MacBook Pro, Air, Retina (with pictures)

    Using Thinkpad Trackpoint USB Keyboard with MacBook Pro, Air, Retina (with pictures)
    The purpose of this discussion thread is to:
    (1) Get community thoughts around using alternative and complimentary mousing approaches with MacBooks 
    (2) To share a current and searchable set of resources for those interested in leveraging a best-of-both-worlds approach for using a non-Apple Trackpoint Keyboard with an Apple MacBook.
    (3) To level-set the fact that a Thinkpad Trackpoint USB Keyboard works with MacBooks automatically and instantly out-of-the-box.
    Note: I created this discussion because I found that all the other discussion threads related to using a Thinkpad Trackpoint Keyboard with MacBooks were archived and therefore I could not post my thoughts there.
    I have been using MacBooks for 3+ years now.  Airs, Pros, Retinas etc.  I LOVE the built-in MacBook Apple Trackpad.  It is wonderful.  Apple has no equal as far as Trackpads go.
    In addition, I have been using the Thinkpad Trackpoint USB Keyboard with my MacBooks for ~2 years, and below is why I have found BOTH the Apple Trackpad and Thinkpad Trackpoint to be great.
    The Trackpoint and Trackpad both have their sweet spots.  Personally I use the built-in Apple Trackpad on my MacBooks when I'm using my MacBook for less than 1 hour, loosely speaking.  If I am going to be heads-down for more than 1 hr writing, reading, surfing, graphic designing, programming, workshop facilitating, teaching, mindmapping, presenting, demoing, etc. then I pull out my "Lenovo Thinkpad USB Keyboard with Trackpoint (55Y9003) > https://www.google.com/search?&q=lenovo+thinkpad+trackpoint+usb+keyboard
    I know many will laugh at me for using a Thinkpad Trackpoint Keyboard with a MacBook...  Keeping an open mind, let's just agree that there is historical precedence for alternative mousing devices.  If I could only choose one, I would use the Apple MacBook built-in Trackpad exclusively, however with alternatives come potential benefits.  Keep in mind that Apple, Microsoft, Logitech and many other companies make millions of dollars each year providing alternative peripheral devices for computers, and mousing is no exception.  Regardless, I just want to share my positive experiences using both. :-)
    Why should you care?  For *some* people the following is true and meaningful.  The Trackpoint (the little red eraser head stick thingy) in the midle of the keyboard enables useful and unique dynamics/use-cases, including:
    You don't have to take your hand(s) off the keyboard to mouse
    You can independantly click without accidentally moving the mouse (Yes I know some people don't have issues with this)
    You don't run out of finger-gesture runway when you're moving your mouse across the screen (I know this is a gray area for some people)
    For mouse-movement-heavy applications (e.g. Graphics, drawing, etc.) the Trackpoint *is at times* more exacting
    Below I share some pictures (which I know *look* ridiculous to some people, but none-the-less help demystify what this looks like.  And, while ridiculous looking, it is actually quite thin and elegant once you get over the initial shock of seeing these two diverse technologies combined in this way.
    Rest assured, the keyboard shown below (google "55Y9003") is VERY light, thin and fits in almost any laptop case/backpack easily so it is not a big deal to carry it, if you work on-the-go.  In addition:
    It is UNCANNY how well it fits on top of the keyboard space of all MacBooks. 
    It fits perfectly around the corners of the MacBook Pro/Air/Retina keyboard
    Note: I took one of the 5 rubber feet/pads off the bottom of my keyboard, the one in the middle
    Lastly, you can actually use the built-in Apple Trackpad at the SAME TIME as the Trackpoint Keyboard. 
    It is quite a nice best-of-both-worlds approach for people that like the benefits of the "Why should you care?" use cases above.
    Please reply and comment with your thoughts and please let's keep it positive, constructive and friendly :-)
    Pictures Below:
    My two Retina MBPs, one with and one without the keyboard, so you can easily see the difference.  (As if you wouldn't)
    A slightly closer-up shot of just the RMBP with the Trackpoint Keyboard on top
    Please reply and comment with your thoughts and please let's keep it positive, constructive and friendly :-)

    Newer Bluetooth version of the ThinkPad External Trackpoint Keyboard available...
    The new version is smaller, so you can use your MacBook Trackpad at the same time as your Trackpoint keyboard.
    Here is the Lenovo model/Part Number# 0B47190
    Here is a picture of what it looks like:
    Note: Just like the older larger USB model keyboard, there is a rubbery footpad in the middle of the bottom of the keyboard that I just peeled off.  Otherwise, it makes the "H" key press accidentally under-neath the keyboard.  Once I took that off, it fit perfectly over and around the built-in MacBook keyboard, so I can optionally put it on top of my MacBook for easy typing. :-)

  • Thinkpad ultranav USB keyboard to PS/2 kvm switches

    Hi
    Can I have some help / info.
    My problem is that i have a Thinkpad Ultranav USB keyboard ( 55Y9012 ) and need to connect to a old PS/2 KVM switches.

  • Thinkpad E530 USB 3.0 and windows 8.1 problem

    Hello, I have a problem with Windows 8.1 Pro x64 and USB 3.0 speed. When I connect a USB 3.0 device I can reach only the speed of USB 2.0. In Windows 7 everything works fine. The notebook is Thinkpad E530 with Intel H77M chipset. All the drivers are installed from the Lenovo support page. Do you have any suggestions? Thanks!

    Hi,
    in this blog, it is just related to Internet Explorer, not the lock screen camera, it can be found at the GPO.

  • Ipod Nano (1st Gen) no longer connects at usb 2.0 speeds

    I have had my nano since it was released almost 2 years ago. When I got it, it connected to my computer (running Win XP) at usb 2.0 speeds, however about 5 months ago, it stopped connecting at this speed and only connected at 1.1 speeds causing very slow updates. I assumed it was my old computer and lived with it. However I just bought a new computer, running windows vista, that has all usb 2.0 ports. I finally tried to connect my ipod this week (I waited until the new ITunes was released), and on the new computer it still connects at USB 1.1. I get the message in windows that says it could operate faster if connected to a usb 2.0 port. I have tried all usb ports on the computer, tried restoring the ipod to factory settings, rebooted, etc, but it still only connects at the slow speed. All other devices I have connect at USB 2.0, except the Ipod. Has anyone else experienced a similar issue? Does anyone know a solution?

    Yes you have a one year warranty from the date of purchase from Apple. Go to this link and on the bottom right hand side it will ask you to enter your serial number and will tell you if you are still under warranty. http://www.apple.com/support/
    If you are you can take it to a Apple store, or request service online here http://depot.info.apple.com/ipod/
    If it is out of warranty you can google a third party service provider and get it serviced out of warranty. There are two that I know of that provide free diagnostic service. You only pay for shipping and they will tell you what is wrong and what it will cost to fix. They are ifixipodsfast.com and ipodmods.com but there are others also (I just have no experience with them) Good luck and as was stated it should charge from your usb. and just for grins, look at the docking connector on your ipod and see if there is any obstruction that is obvious.

  • Help please-USB 2.0 drive only working at USB 1.1 speed (KT3 Ultra2-C, MS-6593)

    Help! I have an MSI KT3 Ultra2-C, part no. MS-6593, running WinXP Home.  According to the manual it has six USB 2.0 ports, but I can't get a USB 2.0 external hard drive working at USB 2.0 speed.  The drive is currently connected using the "D-Bracket 2" which the manual says supports USB 2.0.  In my BIOS all USB ports are set to enabled.
    The drive was detected by Windows XP, but when it installed I got a warning that it is not connected to a full speed USB port.  The drive is only transferring about one megabyte per second of data, which I'm guessing means it's running at USB 1.1.  When I use Sisoft Sandra to look at my port information, it lists "Standard Enhanced PCI to USB Host Controller" and then three listings for "Via Rev 5 or Later USB Universal Host Controller".   All of my USB devices including the new drive are shown mapped to the "Via Rev 5 or later USB Universal Host Controller"  so the "Standard Enhanced PCI to USB Controller" shows no devices connected.   Even though all my USB ports are physically filled, they are all mapping to the "Via Rev 5" controller, which I think is a USB 1.1 controller.  This makes me think if I can somehow force these devices onto the Standard Enhanced PCI to USB Host Controller, they will work at USB 2.0 speed?  How can I make devices use the right USB 2.0 controller instead of the Via USB 1.1 Controller?
    Windows Device Manager looks kind of strange, under USB Controllers it first lists the "Standard Enhanced PCI to USB Host Controller".  Then it lists my USB cable modem, USB printer, and USB hard drive on the following lines.  Then it has several lines that say "USB Root Hub".  Then it has three lines that say "Via Rev 5 or later USB Universal Host Controller".
    Please help me get this external hard drive running at full speed...I'm stumped and thought this USB stuff was all plug and play, and expected my USB 2.0 drive to work on this USB 2.0 motherboard.  Thanks for any responses.

    Go Here: http://www.msi.com.tw/program/support/driver/dvr/spt_dvr_detail.php?UID=357&kind=1 and download the Drivers and the Update. Then go into your device manager and click on the host controller of the USB devices and update driver, then select the drivers that you downloaded and restart your computer. once restarted go back into device manager and make sure that what was once "standard host" controller now shows "Enhanced USB 2.0" controller. Hope that helps.

  • Casio Exilim EX-Z1000 USB Cradle Transfer Speeds

    I just picked up this EX-Z1000 camera and soo far am very happy with it. I do notice however that the transfer speeds are far slower then USB 2.0 should be. It takes me around 30 minutes to move a 1gig movie file off the camera. I have tried a different memory card as well to see if it was the card but they both are slow.
    So I figure it has to do with the cradle or Mac OS not supporting full usb 2.0 speeds. Does anybody else have this problem? Does anybody have a Casio Exilim with a Cradle that gets good transfer speeds?
    Thanks in advance.
    G5 2.3 Dual - MacMini 1.42 - iBook G4 1.33 - PowerMac G4 500   Mac OS X (10.4.7)  

    I have the same camera. It has a USB-1 interface. The Casio "FAQs" indicate that it's "compatible" with USB-2 ports but that's pretty much a meaningless statement. The spec REQUIRES that USB-1 and USB-2 devices communicate with each other. Obviously, such an interconnection must run at the slower USB-1 data rate.
    BTW, you'll find that it has the world's worst user manual. However, once I figured out how to get it to do what I want, I'm really pleased with it (except, of course, for the USB issue).

    I have the same configuration as you.
    I found this thread trying to locate the drivers for the same 3 devices shown in your device manager screenshot.
    My USB 3.0 however seems to go at the proper speed. How are you checking the speed ?

    The USB 3.0 interface is capable of a very fast connection, but it's only as fast as what's connected at each end. FWIW, I just backed up a rMBP to a Toshiba external 3TB drive over USB 3.0 and speeds reached 135 MB/s according to Activity Monitor (226 GB in 34 minutes).
    But what makes a difference is the speed of both the source and the destination, as well as what's being transferred. The source was the internal SSD. The top speed was for large files such as virtual machine files. The speed dropped to less than half that when the files were very small. The destination was also the outermost partition on the HD in the Toshiba. If it had been the innermost partition, the transfer speed would have been a lot slower.
    Quoting USB 3.0 speeds for various devices is largely an advertising gimmick. The same is true for SATA III vs SATA II hard disks. In both cases, it's unlikely that the device can come anywhere near what their connection mode is capable of.

  • Why is my USB 3.0 drive running at USB 2.0 speeds?

    (data for visual reference)
    USB 1.1 - 12 Mbit/s
    USB 2.0 - 480 Mbit/s
    USB 3.0 - 5 Gbit/s
    SATA revision 1.0 - 1.5 Gbit/s - 150 MB/s
    SATA revision 2.0 - 3 Gbit/s - 300 MB/s
    SATA revision 3.0 - 6 Gbit/s - 600 MB/s
    When COPYING (not updating) large volumes of data from my internal Segate SATA-III Hybrid drive to an external Seagate USB 3.0 drive, this is what is happening:
    Both using OSX
    Both data COPY (not updating / integration)
    rsync (terminal interface) - 50MB/s transfer or 480Mbit/s (exact USB 2.0 speeds)
    copy (desktop drag-n-drop) - 1GB every 15-18 seconds (again, exact USB 2.0 speeds)
              1GB * 8 = 8Gbit / 15 = 533,333,333 or about 500Mbit/s
              1GB * 8 = 8Gbit / 18 = 444,444,444 or about 444Mbit/s
    [So, what I have read about rsync -vs- cp is true -- they are identical for fresh copies.]
    But this means that either Seagate or Apple is lying about supporting USB 3.0. I read a report in Feb 2012 that while Apple claims to support USB 3.0, they have not enabled the driver to force people to upgrade to Thunderbolt adapters. Did this change with the Summer 2012 and new models?
    The ABOUT THIS MAC profile says my USB 3.0 devices are enabled to transfer up to 5GB/s, but clearly, they are running at EXACTLY USB 2.0 speeds.
    Even if the Seagate external drive is just SATA-I, then it should be able to deliver 1.2Gbit/s -- 3x what I am seeing! The fact that the speeds are EXACTLY USB 2.0 tells me the MacBook Pro, while claiming USB 3.0 speeds is nothing more than a USB 2.0 port.
    Can someone explain what is happening?
    kai

    I am having the exact same issue on my 2013 MBPr.
    I have two Seagate GoFlex USB 3.0s, one plugged into the regular 3.0 port (450MB/s) on the left and the other plugged into the high-speed (5GB/s) 3.0 port on the right. When doing a simple copy/paste from the one drive to the other, I observe the following speeds:
    Peak Read (USB 3.0): 36.2Mb/s (288Mbit/s)
    Peak Write (USB-HS 3.0): 48.7Mb/s (384Mbit/s)
    This is far below the 620MB/s for 3.0 and is more around the 35MB/s USB 2.0 standard.
    So, I'm likely to agree with the original compaintant that the 3.0 standards aren't being employed by the MacOSX USB drivers and I'd hope to see a fix soon for these issues lest people start moving off of the Mac platforms to other vendors who adhere to industry guidelines.

  • Ipod will not operate @ USB 2.0 speeds

  • Thinkpad X300 with windows xp sp2 gets blue screen after standby.

    We have a Thinkpad X300 (with windows xp sp2) gets blue screen after standby. I mean after you close the lid then open it. Anyone has see this kind of behave before?
    Thanks,

    I have found the solution to this problem - hope you are still watching the thread.
    Express install in parallels seems to be the culprit. Do a custom install instead and set your own virtual hard disk size. I set mine to 12 Gb (12000 Mb)and made it a fixed size instead of "growing" or whatever the heck parallels calls it. I also chose shared network instead of "bridged" (I read that someone else had identified this as part of the problem).
    After making those changes it worked like a charm.

  • External usb 3.0 drives running on usb 2.0 speeds only

    I have 2   2TB USB 3.0 external HD (a Toshiba 2TB Canvio Basics USB 3.0 and a WD My Passport Ultra).
    Both have a maximum transfer rate of 30 MB/s write and 40 MB/s read. This seems to be rather USB 2.0 speed and not USB 3.0.
    According to the specifications of the Macbook Pro Retina it does support USB 3.0.
    Any ideas why my 2 drives both are not handled as USB 3.0 devices, but as USB 2.0?
    Is there a way to tell what mode OS X is using?

    I suggest you contact the hub manufacturer that made yours (since you have apparently identified your problem area) to see if they have any guidance.
    In answer to your question, I do not know of any way to control the hub from your computer.
    Incidentally, are you sure the hub goes to sleep? That would be unusual, I think, to have a dumb device go to sleep.

  • I am trying to get better playback rendering speed Premiere CS6

    I am new to Adobe Premiere CS6.  I am trying to get faster playback rendering speed from my machine.
    Windows 7
    i7 4790K Haswell overclocked to 4.5 (watercooled with Corsair)
    16 GB DDR3@799MHz
    Asus Z87-WS (4 double graphic card slots)
    Geforce GTX 760 (Primary)  GPU hardware acceleration enabled
    Quadro FX5800
    250GB Samsung solid state C: (Windows and Adobe)
    250GB Crucial solid state (Scratch)
    2TB Seagate 7200RPM (video files)
    3TB Seagate 7200RPM (storage)
    Seasonic 1000watt PSU
    I am primarily editing GoPro videos with effects like TimeWarp or Twixtor and color correction.
    I have tried to run the PPBM6 program with no success. I kept getting failure to access files.
    I have been looking at adding a second GTX760 with SLI so they will work together.  And possible removing the Quadro if it is slowing things down.
    Any advice would be appreciated.  Thanks!

    ...are you SURE your 760 GPU is "enabled" by PPro, and giving you the option of "Mercury Playback Acceleration" under  "General Preferences" ??? If the "Mercury Acceleration" is GREYED OUT and limits you to "software Only", go to Studio 1 website and learn to apply the well known "hack" to enable your 760 in PPro,OR, download their simple program to do it for you.
    ...Your machine is POWERFUL....especially with your CPU overclock......you MAY want to increase your memory to 32 GB if you are using After Effects....even PPro MAY run better with 32 GB, depending on your workflow.....most systems like yours have at LEAST 32GB system memory.
    .....The GoPro codec is natively HIGHLY COMPRESSED and difficult to process, even for beefy machines. That is why they provide the free Cineform tool,( which used to be an expensive professional editing codec), to convert some,or,all of your footage to a more "edit friendly" AVI codec, which will FLY on your machine. HOWEVER, those new AVI files are HUGE.....TRIPLE the original size and requiring a LARGE and FAST disk transfer system. Right now, your single 7200 drive for your media is your SLOWEST component in the chain. The CHEAPEST improvement for you would be to add another MATCHING 2TB 7,200 rpm drive to your existing one and then use the 2 drives to create a fast RAID 0 directly off the mother board to improve the speed of your "media drive". THEN, you MUST insure that this RAID 0 is DILIGENTLY BACKED UP in case of a drive failure in the RAID. This ALSO means you must protect against an unexpected power failure which could destroy the RAID data if the failure happened during a critical write operation.....so,a good UPS is required.
    You can OBSERVE how the various components in your system are performing while performing strenuous tasks by bringing up the "task manager" window and watching the CPU load.... if all cores are PEGGED at near 100%, you are "CPU bound". As you are ALREADY overclocked, you can't do anything other than to TRANSCODE your footage to the free Cineform. Your ENABLED GPU can be observed....real time....using the free MSI Afterburner,( or, similar).  Certain operations are accelerated by the GPU with PPro....not ALL!!  Scaling and some effects will use use the "Mercury Acceleration" while rendering previews AND during export.In some cases, rendering previews,or, exporting can be sped up by TEN TIMES by Mercury Acceleration. Watch the "GPU Usage" on Afterburner to see if the GPU is indeed being used, and if you are "saturating" it to its capacity of 100% with accelerated effects.
    Make sure your Windows is fully updated to the current time........make sure your NVidia 760 has the most recent driver and DON'T use the Quadro for now. Set your "Windows page file" to be STATIC on your "C" drive at 24GB. Disable "Hibernation" Set all drives NOT to allow "indexing". Do NOT allow any spinning HDD to be over 50% filled....performance WILL decrease.....make sure any HDD is defragged,( do NOT defrag an SSD ! ). Stop all unnecessary processes, esp. anti-virus programs, while editing. Find out how to best "tune" windows to speed it up at the PPBM 6 and 7 websites.
    BE AWARE that the "run of the mill" SSDs use cheaper Sandforce controllers, and are less suited to handle highly compressed digital video files. Samsung PRO models and recent Crucial M550 series SSDs ONLY are recommended for video use. Both these non-Sandforce SSDs maintain high WRITE speeds,( over 400MB/sec), AND maintain their high speeds after reaching their "steady state" condition. Cheaper EVO series and non-Marvell controlled SSDs MAY lose their fast write speeds over time and SLOW YOU WAY DOWN !!!  Test your current SSDs by transferring large video files between them  and watching MB per second that appears under "details" in the pop up window during transfer. Make sure none are slow.....test them with HD Tune Pro as well.
    Certain non-Adobe plug-ins and certain effects may NOT use all the CPU threads well,or, may not use the GPU.....forcing the CPU to do additional work. You will have to identify problem plug-ins,or, effects by switching them on and off to see if any cripple your system.
    Your machine is POWERFUL.....go to PPBM7 website and read the "tweakers" page to learn more....then, register for free and TEST your machine with their video benchmark test for PPro. It should do WELL.....AND it will help identify if you have any "bottlenecks" which are impairing your system.
    Good Luck !!!!!.....THEN, start using CC 2014.....like Patton said : "...all glory is FLEETING !!"......so is the lifespan of former PPro versions !!!!!!

Maybe you are looking for
