I use a dongle to get wireless from a hub yet I keep getting a message saying this highspeed device isn't working properly as I'musing a USB 1.0 and need a 2.0 of which I've got 6 ports??? which isn't true as there is only two...yet when I check the files the laptop does have USB 2.0...???

Anyone help at all???

    My dongle is in my laptop all the time (so i can get the wireless)...the hub is compliant...never plug the hub into the computer as its in a different room (thats why trying to get wireless) comesup pretty much whenever I replug the dongle in or turn the computer on...

    I'm sure the laptop and dongle are USB 2.0 yet its saying the dongle is plugged into a USB1.0 port???

    Hmmm according to &,2817,157...
    reviews, it has 2 Hi-Speed USB Ports Hi-Speed Equates to USB 2.0 Y/N?.
    Wish Lenevo (IBM) would have had a better Specs description then by just saying it has 2 USB Ports, lol.


    Going over your comment, i'm a bit confused regarding the Hub and the Dongle, i.e
    "the hub is compliant...never plug the hub into the computer as its in a different room"
    So where is the hub connected to in the other room? and what is the Hub a wireless device for Networking or a USB Hub with many 2 ports? Most USB Hubs come with 4, so yeah please clarify.

    If I had to take a guess I would say your Dongle isn't USB 2.0 BUT then without seeing and or knowing what mfr and or model they are, I cannot say it for sure.

    Anyway goodluck

    When do you get the message; when you plug the hub into the computer or the dongle into the hub?

    Is the usb hub 2.0 compliant.

    Does it work in usb 2.0 when you put the dongle directly into the laptop?

My take on this is that the usb on the laptop is hardware 1.0 so since it cannot be updated the hub is 2.0 compliant but it is plugged into a 1.0 hardware on the laptop motherboard, you should check your laptop manufacturer to see if there is an update to the software hardware interface. just in case it is a driver issue and not a hardware issue.

Why can't my Dell desktop computer pick up my wireless connection? It keeps telling me a cable is unpluged but the wireless service is working fine.

Most desktop computers, and especially office models, do not have integrated wireless networking like laptops do since they are not portable. They were designed for wired network cabling. If the desktop HAS wireless capability, there would need to be an expansion card installed and a wireless antenna protruding from the back, or it needs a wireless transmitter/receiver dongle plugged into a USB port. If it doesn't have either of these, it probably doesn't have wireless. However, wireless connectivity is as easy as getting a wireless USB dongle for about 35-40 USD.

Hello I have a dell lattitude cpi a series laptop. I would like to get the usb working again with the 2.0 usb wirless plug in dongle. It did work before. Now when I plug in the usb device it tells me to...

IT sounds like you need to download and install the driver for the WPN111. If you recently did a clean install of the operating system, it would have been removed with the clean install. The WPN11 is a Net gear product and you can get the driver from their website. The message that appears for plugging into a usb 2.0 hub you can just close that out. It is just informing you that it will perform better plugged into the usb 2.0. The existing usb on the CPi is usb 1.1

Ibm x22 doesnt recognise external DVD drive, keeps messaging saying could go faster on USB 2 port, but thats it

Did you check in the bios if your USB ports are configured as USB 2? That could fix it.
If not possible, try uninstalling the USB Root Hub devices in the device manager, that can fix some USB problems.

Laptop keeps searching for unnecessary driver

Might be a good idea to try picking up a driver anyways. Any kind of USB device whether it be a printer, a flash drive, or a USB hub requires a driver for communicating with the device. I'd suggest taking a look on Targus' website and downloading drivers specifically for your model of hub, for your OS. You might be pleasantly surprised.

Power Surge error message




I guess that this could be your error message:

"Error message when you wake up a Windows XP-based computer from hibernation or from standby: "Power Surge on Hub Port: A USB Device has exceeded the power limits of its hub port"


If it is the case, please try below solution:




When you wake up a Microsoft Windows XP-based computer from hibernation or from standby, you may receive the following error message:


Power Surge on Hub Port: A USB Device has exceeded the power limits of its hub port. This error message is displayed even if there are no USB devices connected to the computer.   WORKAROUND loadTOCNode(1, 'workaround'); To work around this issue, disable the USB 2.0-enhanced host controller.

Note When you disable the USB 2.0-enhanced host controller, you lose USB 2.0 functionality. That is, you revert to USB 1.1 functionality.

To disable the USB 2.0-enhanced host controller, follow these steps: 1. Right-click My Computer, and then click Manage. 2. Under Computer Management (Local), click Device Manager. 3. In the Device Manager pane, expand Universal Serial Bus controllers. 4. Right-click the USB 2.0-enhanced host controller, and then click Disable.

Note The name of the USB 2.0-enhanced host controller may vary. 5. When you receive the confirmation message, click Yes. 6.

Close Device Manager.



I hope that this should resolve the issue for you.



Please let me know the result. 


you can mail me at for any further assistance on this issue.


I'll be glad to help you.
