How To Install USB 2.0 Controllers - Help !!!

Hi, guys! I got a virtual machine. My host is XP and guest is also XP. On my guest XP, when I plug in my iphone through the usb, the guest XP sees my USB 2.0 as a USB 1.1. I get this message:
"there are no high speed hub controllers installed on this computer".

It's important that I get my guest XP to properly see my iphone. How do I get my guest to use/install USB 2.0 controllers?

 

Why would you have two same os? are your driver match?

 

I too am trying to run a USB 2.0 device in the virtual environment and am forced to use it as a USB 1 device.
I am runing XP Pro in both the host and virtual machine because that is the only way to run two identical film scanners on one computer. The scanner that is running in the virtual machine scans at about 1/10th the speed of the host machines scanner.
I have read in the Parallels Workstation user guide on page 164 "The current version of Parallels Workstation emulates the 8 -port 2.0 and 2-port 1.1 USB controller.This means that up to eight USB 2.0 and 2 USB 1.1 devices can be connected to a virtual machine simultaneously."
But the user guide under the help menu says"The current version of Parallels Workstation emulates 2-port 1.1 USB controller. This means that up two USB 1.1 devices can be connected to a virtual machine simultaneously."

Why am I unable to use USB 2.0 devices?
Does this version of Workstation not utilize USB 2.0?

Any help would be greatly appreciated.

How to determine whether you do not have to upgrade
You do not have to upgrade the USB 2.0 support if any one of the following conditions is true:

* You purchase a new USB 2.0-capable system that came with Windows XP Service Pack 1 pre-installed. Your original equipment manufacturer (OEM) makes sure that the system has the latest USB 2.0 driver stack.
* You already have Windows XP Service Pack 1 installed on the computer. You add a new USB 2.0 compatible PCI add-in card. In this situation, the latest Windows XP Service Pack 1 drivers for USB 2.0 are auto-selected during driver installation.
* You purchase and install Windows XP with Service Pack 1 included on the CD-ROM.
* You purchase a system from an OEM that slipstreams and pre-installs Windows XP Service Pack 1. Your OEM makes sure that the appropriate USB 2.0 drivers are identified and are installed on the system during GUI-mode install.

How to upgrade to the USB 2.0 Enhanced Host Controller driver in Windows XP Service Pack 1
If your computer supports USB 2.0, and you have a pre-installed USB 2.0 driver from the OEM, you can continue to use the earlier pre-installed drivers for USB 2.0. You can do this even after you install Windows XP Service Pack 1.

To upgrade to the USB 2.0 Enhanced Host Controller driver in Windows XP Service Pack 1, follow these steps:

1. Make sure that Windows XP Service Pack 1 is installed. Make sure that you have restarted your computer if you receive a message to do this.

2. Open Device Manager. Locate Devices by Type.

To open Device Manager, either run Devmgmt.msc at a command prompt, or follow these steps:
1. Click Start, right-click My Computer, and then click Manage.
2. Expand System Tools, click Device Manager, and then click Devices by type on the View menu.
3. Right-click USB 2.0 EHCI Host controller, and then click Update Driver.

You can find the USB Host controller entry in either of the following locations:
* Universal Serial Bus Controllers.

Advanced information
USB 2.0 is a specification revision of the original USB 1.1 specification. USB 2.0 was approved April 2000. The corresponding EHCI specification was finished March 2002.

Windows XP did not include support for USB 2.0 technology for the following reasons:

* There were no production quality EHCI 1.0 compatible host controllers.
* There were not enough production-quality USB 2.0 devices for testing.

The Windows XP Service Pack 1 installer is designed to update all drivers and all files that are included with Windows XP. Because USB 2.0 drivers are not included with Windows XP, you must follow the steps in this article to obtain the latest drivers after you install Windows XP Service Pack 1.

thanks.
