USB 3.0 port thinks it is USB 2.0

I just bought a new HP ENVY 15-j101tu Notebook PC. When I plug the external USB 3.0 hard drive the system pops up message saying the device can perform faster when connected to USB 3.0. The speed of file transfer from laptop to the external hard disk is then very slow. To my understanding this laptop comes with all USB 3.0 port. 
Please help to fix this problem. Many thanks in advance

The usb ports on the right and left hand side are usb 3.0.
What is the brand and model of your external usb 3.0 hard drive?
Have you tried the usb 3.0 external hard drive on a different PC to see how Windows reacts to it?
Connect a usb 3.0 usb flash drive to all ports to see how the notebook's OS reacts.

  • IPod not recognised by USB 2.0 port but is by USB 1.0, how come?

    iPodnano_1GB,
    My silly ipod nano isn't being recognised by my recently installed usb 2.0 port.
    The port is working fine as it recognises my creative player just fine, and the pc is fine as my old usb 1.0 recognises the ipod just fine.
    So how come the usb 2.0 isn't picking it up. It gives an error message of 'unrecognised usb storage device'.
    Hope you can help, thanks.

    For those who come here...try this forum: http://whirlpool.net.au/forum-replies-archive.cfm/697583.html

  • Forcing USB 3.0 port to act like USB 2.0 port?

    Hello all! Firstly I would like to say that I am aware that USB 3.0 is backwards compatible, but that does not answer my question.
    Long story short, I am attempting to use a logitech g27 controller through parallels, on windows 7, and it is giving me issues.
    Based on the vast knowledge of the internet, I am under the impression that the USB 3.0 is causing compatibility issues, based on others peoples experiences.
    Is there a way to explicitly make the USB 3.0 port a 2.0 port on my macbook air?
    Thanks!

    I will definitely keep this in mind as a backup as I would prefer to not have to purchase anything else. Thanks for the suggestion though!

  • 870A-G54 doesn't boot devices from USB 3.0 port

    I have the latest BIOS, and USB devices boot just fine when plugged into a USB 2.0 port. My current USB stick of choice is formatted FAT32. But when it's plugged into a USB 3.0 port, it's not even listed in the boot menu, nor can the device be used to flash the BIOS. It's simply not there. I can use USB 3.0 ports like normal once an operating system has loaded.
    I have had this issue since I purchased the motherboard about a year ago. I don't recall seeing anything in the documentation that mentions this limitation. I suspect that the board's USB controller may be faulty. However, performance and connectivity is otherwise unaffected. It's a strange quirk, and it's now bugging me sufficiently to ask for help. Google has been of no use, and I searched the forum and couldn't find any info here either. So, does anyone know what might be going on here?
    Rest of the relevant specs:
    1090T stock
    12GB of RAM (don't ask)
    Sapphire 6850 stock
    Spinpoint F3 1TB

  • USB to Serial port adapter - Mac thinks  it's a modem

    I’m trying to connect my Mac’s USB port to a Sony Beta SP recorder's Serial Port using a generic USB to Serial adapter which uses the Prolific PL-2303 chip.
    I’m using the latest Prolific Universal driver, but when I plug in the USB cable I get a message that a ‘new network device has been detected’ and suggesting that I use System Preferences to set it up. But in System Preferences it seems to think the USB to Serial adapter is a modem and is looking for a phone number and other configuration data.
    Does anyone know how to get it to work as just a serial communication device to my Sony’s serial port? If I get it working I'll be connecting it to an RS232 to RS422 adapter to talk to the Sony port.
    Thanks.

    Thanks Andy.
    I'll have a go again. It was late last night when I was trying to set it up, so maybe a fresh brain will have more success. I did try to 'Cancel' the network preference window that opened, but got the impression that it would not work unless I did 'something'. Someone else told me I could cancel that message permanently within System Preferences, so I'll try that too. Yet another bit of advice I got was that I would have to install 'MacPorts' and run something called 'Minicom' to set up the serial parameters. Windows was so simple by comparison
    As a non-techie (at least in all these software and protocol issues) I'm more than a little confused.

  • XP thinks my Mac Pro USB 2.0 ports are 1.0

    For some reason, when my computer starts up in XP, an alert comes up and warns me that my devices should be using USB 2.0 to take advantage of the best speed available. However the new Pac Pros have 5 USB ports which are ALL USB 2.0.
    Any clue why this might be?

    Thanks for your suggestions, but I need to clarify something.
    When I connect my USB 2.0 Flash drive to the top of the two front USB ports, I get, "This USB device can perform faster if you connect it to a Hi-Speed USB 2.0 Host Controller.  For a list of avaliable ports, click here."  When I click there, I get "VIA USB 2.0 Enhanced Host" and inside of that "USB Root Hub (6 ports)" and inside of that "Unused Port" six times.  The flash drive is recognized as drive G: and the transfer rate is very slow.
    When I connect my USB 2.0 Flash drive to the bottom of the two front USB ports, I get, "USB Devce Not Recognized.  One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it."  The flash drive is not recognized.
    When I connect my USB 2.0 Flash drive to either of the two USB ports in the back that are connected directly to the mainboard, or to either of the two USB ports in the back that are connected to a card in a PCI slot, I get no messages and the flash drive is recognized as drive G: and the transfer rate is exactly the same as when it is attached to either of the front USB ports.

  • HP 2005pr USB 2.0 Port Replicator - Video not with my Surface Pro 3

    Hi everyone,
    I've spent tons of hours already trying to get the HP 2005pr USB 2.0 Port Replicator working with my Surface Pro 3 and no luck. I mean, the USB replication / hub works, meaning that if I plug in a USB mouse / keyboard, they work. It recognizes the device in Device Manager and the ViewSpan application is running. But if I plug in a display in the VGA, nothing happens, no monitor gets detected, and even if I "force-detect" one it still doesn't display anything.
    I've tried with 3 driver versions so far:
    0.2.5 - not working at all. Reboots my Surface while installing. (this one is on the device itself).
    3.X - which is the first with support for Windows 8 I think. I can install it and everything works as described above - meaning no VGA.
    5.3.X - same story as above.
    I've tried uninstalling, restarting and uninstalling several times with both versions. No luck. And I've literally been on every forum where people have problems with the replicator and nothing helped.
    Anyone had any luck getting such a setup to work?
    Or any ideas on how to get it to work?
    Thanks.

    Hi @blinkk2
    I see that you are having problem connecting an external monitor to your Microsoft Surface Pro 3 through the HP USB Port Replicator. As the USB ports are working with the mouse and keyboard we know what the Port Replicator itself is working this is going to be something with the drivers on the Surface. I would recommend contacting Microsoft Support to see if they can recommend a graphics driver for you.

  • USB 2.0 stopped being recognized by USB 3.0 port

    Hey all,
    Two days ago, I was syncing my iPod Classic (USB 2.0) with iTunes and I also had my USB 2.0 Time Machine drive plugged in (I do not think it was backing up at the time), both of these devices were plugged into the USB 3.0 ports on my 15" MacBook Pro (Mid 2012). All of a sudden, my MacBook informs me that both devices were disconnected. For the next 30 minutes, these devices connected and disconnected sporadically. I tried restarting my MacBook multiple times, I reset the PRAM multiple times, I reset the SMC multiple times, I booted into Windows 7 (I use Boot Camp) and both devices show up as unrecognized. They do not show up at all on the OS X (10.10.2) side of my computer. What's strange though, is that all USB 3.0 devices work perfectly. I tried an old USB 2.0 flash drive, didn't work.
    Anyone have any thoughts? I have searched Google and these forums for the last two days to no avail.

    To plug a 2.0 into a 3.0 you are using an adapter? Is this where the problem is? Even with the old flash drive? or did you also try using the 2.0 ports on your MBP? The adapter could be bad or the cables for your external devises. You did the steps you need to do to correct the problem. Other then that it would be a hardware problem. And you would need to take it to an apple store to be checked out.

  • Lenovo Thinkpad E530 - USB 3.0 Ports Not Working Code 10

    Hi everyone, so I own a Lenovo E530 with Windows 7 and just earlier today I plugged in my optical mouse into it, about 10 minutes in, Windows gave me a "not enough power message" for my USB 3.0 ports on the left side and they just stopped working. I have 3 USB 3.0 ports on the left side of the laptop, and one USB 2.0 on the right which works just fine.
    From there it gave me Code 10 for Teredo Tunneling Pseudo-Interface in the Network Adapter section (which I was able to fix via a registry change) and now what is left to fix is the Intel USB 3.0 eXtensible Host Controller which I cannot seem to fix. I have tried the uninstall/reinstall processes, with Intel's own drivers and Lenovo drivers which were just older version of the Intel USB 3.0 drivers, over and over yet it is still stuck on Code 10, where it will not start.
    I never really overused the USB ports either, aside from plugging in a portable USB fan and portable hard drive here and there, and a USB dongle for a wireless mouse and keyboard (Logitech all-in-ones), that is pretty much all I have done with it. I do not believe the ports are not bad or anything, although it may be a hardware problem, but all 3 USB ports still give power on my fan and external HDs when I plug it in, it is just that Windows does not recognize it and nothing happens when I plug something into. But on the other hand, the USB 2.0 port reads just fine and recognizes everything. I have also tried the Troubleshooter multiple times, but everytime it tries to reinstall I get the "Failed" message.
    Here is a screenshot of what I am talking about.
    http://i.imgur.com/mKqWpFU.png
    http://i.imgur.com/RLkbyHY.png
    I have tried reinstalling and uninstalling the Intel USB 3.0 eXtensible Host Controller Driver for W7 using the ones listed on the drivers page through Lenovo and using the newest version fround on Intel's webpage as well. Having done these I still could not get it working, so I did a full reformat of the Hard Drive, from there I am able to get the USB 2.0 and 1 of the 3 USB 3.0 ports to work (the very top one above/left of the HDMI port) and recognize devices when I plug them into Windows. But this is working through not having the USB 3.0 Driver installed and just the basic one without having any updates/drivers installed on. Once I install the USB 3.0 Driver back it, it goes back to the original problem.
    The problem still persists even though I have done multiple reformats, uninstall/reinstalls, updating to newest drivers and BIOS, etc. I have owned and still own a whole family of Lenovo laptops which still work perfectly fine, but this is the first time I have seen anything like this go wrong in a laptop. Is there anything else I can try to fix this problem? The laptop just went out of warranty a few months ago, and if I were to send it in and get it repaired would it cost me a lot?

  • How do I remove USB virtual printer port

    Im having some problems printing (see different thread) so I have removed all reference to the printers and drivers (nothing in devices and printers; nothing in print management), Ive removed all USB devices (except the mouse) switched off and removed the
    battery for 60 minutes. The restarted.
    Still 3 USB ports
    Ive tried
    http://www.ehow.com/how_6688235_delete-usb-virtual-printer-port.html  but I cant see the virtual USB ports in device manager
    http://www.ehow.com/how_6910965_delete-usb-printer-port.html  But I cant (unsurprisingly) find the ports in installed programs
    http://www.ehow.com/how_5869559_remove-usb-printer-port.htmll  (delete form devices and printers) But when I highlight the port from printer properties and click delete I get "selected port cannot be deleted. The request is not supported
    Makes me think these are not properly installed ports.
    Ive searched the registry for USB001 and there are 4 USB00? entries all under unknown printer with headings like 6&30e6e7fe&0&USB003. So I tried to deleted all of them. It lest me delete the parameter sub key but I am not allowed to delete the other
    keys (error while deleting key)
    So after a bit of a search I came up with psexec (see link for more details and do take backups and read the instructions)
    http://social.technet.microsoft.com/Forums/windows/en-US/56fed319-a532-46a4-a384-fd795998c4a3/regedit-permissions-access-denied-or-error-while-deleting-key-even-as-admin?forum=w7itproinstall
    And that allowed me to get rid of the ports from the registry but they were still visible in Devices adn printers under ports (after slecting a device)
    So how do I get rid of these wretched ports?
    TFAI

    Hi,
    Yes, you could create a new port for other printer. Of course, you also assign it to a different print if you don't use this printer.
    The detailed steps are below:
    1. Click the START button, click navigate to "Control Panel", then navigate to and click on "Printers."
    2. Once the printers window is open, click on "Add a printer" in the dark blue menu bar.
    3. At the "Choose a printer port" section click on the "Create a new port" radio button then select "Standard TCP/IP Port" for the "Type of port."
    4. At the "Type a printer hostname or IP Address" section select "TCP/IP Device" for "Device type" and input the proper hostname depending on the printer that you are installing, the IPs for all of the different departmental printers can be gotten from the
    main printer help page on this website.
    5. At the "Type a printer name" section type in what you would like to call the printer under the "Printer name" section, this is entirely up to you. Here you also want to make sure that the driver that it says it will install corresponds with the model
    of printer you are installing.
    6. After the installation you should get a section called "You've successfully added [printername]." Here you should click the "Print a test page" button to make sure everything is installed correctly.

  • How to unmount external HDD automatically on USB 3.0 port ?

    Hi All,
    Could anybody help me? I use my MBP on battery power usually and have an external HDD. I gave 10 min. to go sleep. Sometimes I have to leave alone my mac e.g. for a long call or manage something. When I come back my machine is sleeping... after wake up I got an alert about unmounting, should formatting external HDD, because can't read it so on... Is any possibility (automator setting?) to unmount automatically before go sleep? I've read the community's discussion but haven't found a real solution. I think it is not lifelike to look at it very attentively during you do 1000 other things and if the unmounting is so important for OS. I trust there is a simple solution maybe you know it.
    Thanks,
    Zack

    From my point of few its not HDD problem because the HDD works in connection with USB 2.0 port.
    Im wondering if you already tried to update the USB 3.0 driver.
    Did you try this HDD in connection with another computers / USB 3.0 ports?
    I think its worth a check.
    Furthermore I read about some USB 3.0 controller problems from different manufacturers.
    Sometimes it could be possible that some compatibility problems between different devices may arise.

  • USB 3.0 port running at 2.0 speed

    Yes the the the yellow marked driver is installed exactly as you have shown. But the usb device tree viewer software is indicating that the device is working as usb 2.0.  Also I tried to do use the "Crystal Disk mark" to check the speeds, and the speeds were corresponding to USB 2.0. The official HP website doesnt have usb 3.0 drivers listed as it has been done for earlier OS such as Win 8 or Win 7. I have 2 hard disks, both are USB 3.0 so I dont think that there is any problem in the hard disks. HD 1 - Toshiba Canvio 1.0 TB and HD 2 - Seagate Expansion Portable 1.0 TB.  

    I was using win7 so far and had no issues. Recent upgrade to Win10 has caused me this problem.My laptop has 3 usb ports, 2 of which are USB2.0 and one is USB 3.0. However the USB 3.0 port is running at speeds of USB 2.0. My harddisk is seagate expansaion portable 1.0 TB.  Any solutions. I have already done successful online update of all drivers. 

  • IPod not recognized by laptop's USB 1.0 port

    There are a couple of problems here. I have an external hard drive that can only be accessed with a USB 2.0 cable. I had to buy a card with USB 2.0 ports since my laptop only has USB 1.0. When I try to update the iPod (plugged into the USB 2.0 card as well as the external hard drive), everything freezes, goes very slowly, and I can't transfer songs from the external hard drive.
    When I unplug the external hard drive I can update songs from my laptop's hard drive, but the iPod has to be plugged into the USB 2.0 card. When I plug the iPod into the laptop's USB 1.0 port (regardless of whether the external hard drive is connected) the iPod is not recognized, it only gets charged.
    I tried this iPod on a different computer last night and it worked great.
    So two questions: 1) how do I transfer songs from my external hard drive (get my computer not to freeze) and 2) how can I make my laptop recognize my iPod when it's plugged into the laptop's USB 1.0 port?
    Thanks a lot

    Well... from what i am reading about your post, you want to transfer your music from the external hard drive to your laptop. if this is correct then i think that you should open the hard drive into a window and put all the music into 1 folder and drag it onto your desktop, then once the music is downloaded onto your laptop, (if there is enough space) unplug the external hard drive and use the USB 2.0 port 4 your ipod w/o the hard drive. sometimes when i plug my ipod into my PC it will stop everything for 5 minutes then it starts to work. so i recommend to plug it into the 2.0 and wait a while and see what happens.

  • 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???
