Guest unni Posted September 26, 2007 Posted September 26, 2007 I have Windows XP Home edition SP2. The computer(Sony PCV-RZ22G) has 6 US2.0 ports (2 in front and 4 in back) I was getting the following message when I connect a HI-SPEED USB device to my USB port. (External HDD) "HI-SPEED USB Device Attached To non-HI-SPEED Hub" Based on General USB troubleshooting in Windows XP info in the MS support site, I uninstalled the USB controller and tried to reinstall it. The reinstallation failed and I can see a yellow warning sign on the USB Controller in the device manager. The installation process comes up with a message "Cannot Install this Hardware" The driver insallation file is missing a necessary entry. This may be because the INF was written for Windows 95 or later I had to do a Windows restore to make make USB working again. But it is still working at USB 1.1 speed. I also obtained and tried the hotfix for KB892050, but it did not solve the problem.
Guest Ace Posted October 1, 2007 Posted October 1, 2007 Re: USB2.0 port is working only at USB1.1 speed On some mainboards, the difference between 'full speed' and 'high speed' is 12 or 480Mbit USB respectively, if I remember correctly. You may wish to verify your computer's BIOS settings regarding the state of the USB ports. Also see the manufacturer's website for any available updates to your mainboard drivers. =?Utf-8?B?dW5uaQ==?= <unni@discussions.microsoft.com> wrote in news:32FE8868-BABA-4762-A32C-B43E0949B284@microsoft.com: > I have Windows XP Home edition SP2.

Is the USB controller card "labeled" with "Enhanced" in the Device Manager? If it is not, then the controller is: 1) Not a USB2 controller. 2) Requires a "specialized" driver from Sony. 3) Not set as "USB2" in the BIOS 4) Defective. To have USB 2 ports, you need to have the "hardware" controller card that does have the USB 2 controls and the required drivers. Microsoft provides the USB 2 drivers only starting at Windows XP.
Guest unni Posted October 1, 2007 Posted October 1, 2007 Re: USB2.0 port is working only at USB1.1 speed Thanks for the replies. Is the USB controller card "labeled" with "Enhanced" in the Device Manager? - "Yes it is labeled as "Enhanced" in the device manager. On the computer is labeled 6 USB 2.0 ports. So I assume the USb hardware is USB2.0 What should I check in BIOS and how can I do that ? Sony does not provide USB drivers in their site. Also they do not have any updates to the BIOS.
