USB 3.0 detected as USB 2.0 hub

I want to add USB 3.0 ports to my laptop (Dell 1545, running Win7 with all available updates).

I installed a Renesas ExpressCard with two USB 3.0 ports.  This map features well uses the drivers of Renesas that accompanies it.  The Device Manager lists as a hub USB 3.0, and several external HDs that have USB 3.0 interfaces work fine when plugged in it.

Now, I need to have more USB 3.0 ports available on this laptop for other equipment.

To do this, I bought an external USB 3.0 hub generic (unknown manufacturer, 7 switch ports and a power adapter which provides 5V @ 2A power supply by bus).

No drivers have been provided with the hub, in fact, it has been announced as not requiring any because Win7 had already installed the necessary drivers.

I plugged the external hub in one of the ports of the ExpressCard and Win7 has recognized, but only as a USB 2.0 hub.  All devices I've tried on the external hub worked OK, but only at USB 2.0 speed.  Device Manager displays the Renesas USB 2.0 external hub as a hub, and it uses the same driver (Renesas v3.0.16.0) as the ExpressCard.  When you try to update the driver, Win7 says it's the best driver available.  I've considered uninstalling the driver of Renesas and tries to install a driver Win7, but I don't know if it works or if it would affect the ExpressCard.

If anyone has any ideas on this, I would appreciate hearing them.

Hi Jerry,

This problem may occur because of conflicts between the towing devices (Renesas ExpressCard and Generic USB 3.0 external hub). It could also be a USB 3.0 adapter generic defective as external devices detect USB 3.0 when it is connected to the ExpressCard of Renesas, in which, they are not connected to the generic adapter.

To learn more about the issue, I you suggest to disconnect the ExpressCard Renesas and then connect the Generic USB adapter only on the computer. Make sure these devices are getting detected as USB 3.0 device. In addition, when you connect the USB adapter to the expresscard, make sure that you have connected to the USB 3.0, rather than a USB 2.0 port. If the problem persists always, so, you can contact the manufacturer of the Generic USB adapter.

  • Problem detection IOGEAR GUH285 USB 2.0 hub

    I just bought this 2.0 hub 4 port USB of IOGEAR (model GUH285). This is supposed to be a plug-and-play hub. Infact, if I connect it to my other computer with windows 7, it works fine. But on this one (Windows 7 too), it's not!

    In PC-1, where he works, it does not install any software device driver. It works and is listed under USB controllers in Device Manager.
    In PC-2, where it does not, it's trying to install a software device driver and it fails. If I look in the Device Manager, it lists under other devices-> hub USB 2.0 with a yellow sign at the front. If I try to update the driver and then manually select the location one or C:\\Windows\Drivers, it can't find it (my assumption was that it takes a generic player already installed on PC - 2 is on PC - 1). I contacted the manufacturer, but they say it should work like him for the other PC running the same operating system windows 7. Can someone help me please.

    by the way, I got it works... had to install manually the usb hub root for her... but now there is another problem... my usb for mouse Logitech M305 wireless receiver would not work with her. Other things attached to the hub as a Western digital external drive, USB in Kingston, dell etc USB keyboard key work perfectly well. Only problem is with the USB receiver. If I connect the M305 usb receiver to the hub, it will try to install a device driver and invariably fails and it lists, as previously, under "other device-> usb receiver" in Device Manager. But if I connect the M305 usb receiver to the other free usb port on my laptop directly, it works very well and it lists as composite USB device. I can see that the driver is 'C:\Windows\system32\drivers\usbccgp.sys' when it is listed as a device composite usb plugged into the USB port on my laptop. It is just plug and play in this case. Is there a way I can manually install this driver specific to the M305 usb receiver when it is connected to the USB 2.0 hub? Hope that I have understood the question.

  • EX7000 with USB 3.0 Hub

    The EX7000 (Extender/Access Point) has a USB 3.0 port. Can I use ReadyShare installation with a USB and USB printer simultaneously by connecting a USB 3.0 hub to the EX7000?

    Hi declanb,

    Unfortunately, the EX7000 does not work with a USB3.0 Hub that you described.
    It is possible to use the hub with only hard drives. But the USB printer does not work with the hub.

  • IBM Thinkpad message: 'this machine can run faster with the USB 2.0 hub.

    Original title: Thinkpad USB 2.0 Hub.

    Hello:

    I have an IBM Thinkpad T-21 which is under Ubuntu & Windows xp.  I primarily use Windows XP.  The pop-up that keeps occurring is "this machine can run faster with the USB 2.0 hub.  Can you tell me how to upgrade my USB 2.0 Hub?  Would like to know because I can't sync my Android phone with my computer until I do it. Thank you.

    Are you sure you copied this error message properly?  In other words, he says that the hub could perform better if connected to a USB 2.0 port?  As far as I can determine that the T21 is not come with a USB 2.0 port, even if you connect a USB 2.0 device (for example a hub), the unit will only race as fast as the port allows it.

    What is the brand and model of your terminal?

    It is possible that the message means the opposite (i.e., your computer has a USB 2.0 port, but the hub is only a USB 1.1 device).

    USB 2.0 was introduced in 2001, so if you bought your computer before 2001, it is likely that you use USB 1.1 or 1.0.

    Open the Device Manager (start > run > devmgmt.msc > OK)
    Expand the category of 'USB Bus controllers'.
    If you see the "Enhanced" work for one or more of the listed devices, you have a USB 2.0 port.  If you do not see "Enhanced", you have USB 1.1.

    If the problem is that the USB port on the computer is not 2.0, so your only solution is to buy a USB 2.0 PC Card adapter.  Example and example 2
    If the problem is that the hub is not 2.0, then you will need to buy a new hub.

  • USB devices connected through a USB 2.0 Hub Stop Responding and are not recognized after Hub reconnects

    Recently, I have this strange problem where if I connect an additional USB device to one of my USB hubs, some of my devices stop working (especially my keyboard and mouse).

    I have two hubs Generic USB connected to my motherboard. My motherboard is an ASUS Rampage II Extreme X 58 who and chips ICH10. It has 4 USB ports in the front and 6 ports on the rear panel (all USB 2.0). I also have a USB 3 controller card that is connected to one of the PCI-E card to the Board of Directors.  I have the following problems:

    1. Connect a USB device to one of my USB hubs (or one of the USB ports on the front panel) causes some of my devices to stop working (especially my keyboard and mouse that are connected via a USB hub). It seems that crashes of USB controller.  If disconnect and reconnect my HUB, windows does not recognize devices connected to this hub.
    2. Now, after the crash, if unplugging the devices connected to the hub and connect it directly to one of the ports on the front or the back of the computer, Windows instantly recognizes!

    Now I'm confused what is the cause of this problem. I had the same computer since the release of the i7 and X 58 and never had this problem (although I don't remember if I used USB hubs right there).

    Why Windows to recognise the devices connected to the hub at the beginning, but not after the crash?

    Why USB devices stop working when I connect to another USB device on my computer?

    And how do I solve this problem?

    AK

    Just a thought by the way.  If the hubs are not powered you can cause the + 5V due to the excessive number of devices not powered up to a point where it causes accidents and able to resume.

    Reduce the number of UN powered can solve this problem,

    First of all, my old 5-port Belkin hub worked perfectly but just leave me about 2 weeks ago. It will appear on the page of familiar devices of exclamation in a yellow circle. I tried to restore my settings of PCs, but in vain. I talked to Belkin and they said because it's a simple device plug-and-play, no driver is necessary.

  • Hub USB 3.0 not found?

    Hi, I'm running Win7 64 bit on a motherboard Asus Z87. I recently did the upgrade from 32 to 64 bits, but this problem has followed me to the new system. The problem is the system apparently cannot detect a USB 3.0 hub, and the drivers from the CD of the motherboard or Intel (probably?) are not detected.

    It is currently listed as an "unknown device" on the control panel with a warning Code 28.

    Key material:

    IUSB3\ROOT_HUB30 & VID_8086 & PID_8C31 & REV_0005 & SID_85341043
    IUSB3\ROOT_HUB30 & VID_8086 & PID_8C31 & REV_0005
    IUSB3\ROOT_HUB30 & VID_8086 & PID_8C31

    I suspect that the problem may lie in the USB ports on my computer case, which are distinct from those provided on the motherboard.

    Any help is appreciated, thanks.

  • ESX 4.1.0 USB troubles

    Hey all, I'm trying to connect a USB to an ESX 4.1.0 server to copy some files on it but I have a few questions.  It seems to be detected (present in dmesg and lsusb), but he does not appear in fdisk-l and I can't ride.

    If I do a 'method' in / dev, no / dev/sda * nodes are present.

    Any help/advice would be greatly appreciated.

    Thank you!

    Hello

    You can't see your USB drive becaused it is transmitted to be mounted on the virtual machines, not the host. Mount it on the host, you must stop the service "usbarbitrator" before plugging the USB:

    1. ssh into your ESX

    2 /etc/init.d/usbarbitrator stop

    3. connect the USB drive

    4. support USB key

    5 do stuff you want to do

    6. umount USB

    7 /etc/init.d/usbarbitrator start

    Fact
