Sounds like something else is chewing up you memory have you got too much allocated somewhere else or control panel/ system /device manager/ serial bus controlers/ std open host controller... update driver, or uninstall and then reboot and windows should hunt it down for you. you may need the driver for it if it cant find it by itself, that means knowing what sort it is (motherboard handbook) and going to site and getting driver.

If your Device Manager shows an ENHANCED USB Host Controller, the system has High Speed USB (USB 2.0) capability.

Types of High Speed USB (USB 2.0) Host Controllers

· Intel Enhanced

· SiS Enhanced

· VIA Enhanced

· ALi Enhanced

· Standard Enhanced

· NEC Enhanced

The system shown has onboard Intel High Speed USB (USB 2.0) with an NEC High Speed USB (USB 2.0) PCI card installed.

The key word is ENHANCED. If you have an ENHANCED USB Host Controller then you have High Speed USB (USB 2.0)

All other types are USB v.1.1

hope this helps

My pc will not detect the usb cable to install my hp c5150. I know there is nothing wrong with the port b/c my computer will detect my ipod and camera. Any ideas why it won't detect my printer cable?

firsty it could be a faulty usb cable else try changing your chipset drivers right click my computer/ computer left clik on manage. computer manager should open left clcik on device manager in your centre screen look for Universal serial bus controllers click on the plus sign look for you universal host controllers you can have from 4 to 8 of them (do not change the enhanced host controllers)
right click one of the universal host controlers click on update driver a wizard should come up look for browse option and next and then look for the option "let me choose driver" and then select the standard usb host controller and apply if you get a microsoft message just click on continue anyway then repeat for the rest of the universal host controllers once all has been changed try installing the printer drivers and when prompted by software to plug in printer you may do so
hope that helps

I keep getting the statement: "Hi-speed USB Device attached to Non-Hi-Speed Hub

This is purely because you have a USB 2 device on a USB 1 port. Open the device manager and expnad the list for Universal Serial Bus Controllers. Right click on any one of the host controllers and select Properties. Select the tab called Advanced and place a tick in "Don't tell me about USB errors".

My Panasonic CF-74 doesn't seem to be detecting anything I am plugging into the USB ports or the COM port.

Some motherboard BIOS's allow you to specify how many USB ports you want enabled
go to your Control Panel, System, Device Manager.

go down to where it says Universal Serial Bus Controllers, click the + sign,
you will see a list of devices, probably something like this
via rev5 usb host controller
via rev5 usb host controller
usb printing support
usb mass storage controller
usb root hub
usb root hub

right click on the ones that say via or intel or SIS, or ALI, or Standard open host controller, and choose uninstall.

you will be asked if your sure, and you will see some of the USB root hubs disappear.

If you are asked to restart, choose no, and remove the other via/sis/intel/etc open host controller (s) from your system, when they have all been removed restart your computer.

when the computer restarts, it will detect the USB controller and connected devices, reinstall the drivers/software

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.

PC can't communicate with GPS unit for initial map load

It will NOT show up under USB controllers. It should appear as "GARMIN Devices" in your device manager. Mine is right under Floppy disk drives. Do other USB devices 'bong' up when connected and 'bong' down when taken off? Of course you have to have your audio on for that. The GPS should 'sound' just like any other USB device when attached or taken off. I find that GARMIN help is of no use. Forums like this have helped me far more.

USB connection problem using Windows 98 Second Edition

The cause of this problem can be traced to both the computer's hardware configuration and Windows 98SE (Second Edition). PhotoMAX cameras and other devices featuring USB (Universal Serial Bus) connections may not work with computers running Windows 98 Second Edition and equipped with the following computer hardware: * an AMD processor (350 MHz or higher) * VIA Technologies USB Host Controller or SiS 7001 USB Host Controller To find out what USB Host Controller is on your system: 1. Click Start > Settings and choose Control Panel. 2. Double click the System icon. 3. Choose the Device Manager tab. A window similar to the one shown below appears. 4. Expand the Universal Serial Bus controllers listing by clicking on the "+" sign next to the listing. 5. Note the type of host controller in the listing. The example above shows the SiS 7001 PCI to USB Open Host Controller.
