passionne Posted October 14, 2005 Posted October 14, 2005 Hello, When I connect a USB 2.0 device, I obtain the following message : "HI-SPEED USB Device attached to non HI-SPEED Hub The unknown usb device will function at reduced speed. You must add a HI-SPEED USB host controller to this computer to obtain maximum performance." In the device manager, I have the following entries : The "standard openHCD USB host controller" and "USB root hub" enable USB 1.1 only. I deleted them then rebooted. But Windows generates them automatically and all my devices are detected on them, and not on the USB 2.0 drivers. I own Windows XP SP2. which are said to include USB 2.0 drivers. Nvidia driver is the 6.66 version. Really, I don't know how to solve this problem. May someone help me, please ? Thanks. Share this post Link to post Share on other sites More sharing options...
yahooad Posted October 14, 2005 Posted October 14, 2005 the disk that came with the motherboard should have drivers there are probably instructions for installing it, but briefly, put the cd in, find the drivers, right click on the device then click update driver (or find it in properties if its not there) then click have disk and scroll to where the drivers are select them and then finish the wizard Share this post Link to post Share on other sites More sharing options...
Dave_Sz Posted October 14, 2005 Posted October 14, 2005 Make sure both 2.0 and 1.1 are enable in the BIOS. There is an option for usb2.0/1.1 or 1.1 only. Share this post Link to post Share on other sites More sharing options...

passionne Posted October 14, 2005 Posted October 14, 2005 Finally, I found the solution : I deleted all the entries related to USB drivers in the device manager. Then, in the control panel, I selected "add hardware". And Windows included both the "standard OpenHCD USB Host Controller " for USB 1.1 and "Standard Enhanced PCI to USB host controller" for USB 2.0. And when I connect a USB key, I no longer have the message, informing me that the device works at USB 1.1 bandwidth instead of USB 2.0 one. I hope that that will help other people. Thanks for your help nevertheless. Share this post Link to post Share on other sites More sharing options...

Angry_Games Posted October 18, 2005 Posted October 18, 2005 you do NOT need USB2.0 drivers if you are using Windows XP SP1 or later do NOT install USB drivers if you ARE using SP1 or later. deleting them in device manager and letting them redetect is a good workaround that many have found Share this post Link to post Share on other sites More sharing options...
