Hello,
I have been having problems with getting USB 2.0 to work on my Windows 7 system since I bought it. I tried to fix it, but it never bothered me too much. Recently it has become more of a problem though. Sometimes I have to disconnect a USB device just to get Windows to boot, and the 1.1 speeds can be frustrating when copying large amounts of data to a flash device. I have a Rosewill USB hub, but I don't think that would cause all my ports (even ports on the front of the computer) to somehow work with only 1.1 speeds.
Some info on my system:
Windows 7 Ultimate x64
Biostar TA790GX 128M Motherboard (http://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=377)
As far as I understand I should have an enhanced USB controller listed on my device manager, but no such device exists as shown here:
I have tried the following with no luck..
1. Updating all my drivers from the Biostar link listed above. I can't install the USB 2.0 driver controller listed (from 2008) as it just tells me 'Device not found'.
2. Disabling legacy USB support in my BIOS.
3. Uninstalling USB devices from device manager and rebooting.
4. I have a Windows update installed that could potentially fix this kind of issue, but it did nothing for me.
So I'm not really sure what the problem is. I don't know if it's a BIOS setting I have wrong (they all seem correct to me), or if Windows just won't let me install the right driver, or maybe it's a motherboard problem. I have no idea, and pretty much have given up on trying to solve this issue on my own.

AMD Standard Enhanced PCI to USB Host Controller chipset drivers. Download drivers for AMD Standard Enhanced PCI to USB Host Controller chipset, or download DriverPack Solution software for automatic driver download and update. Standard Enhanced PCI to USB Host Controller Driver for SAMSUNG - RV409/RV509 working on Microsoft Windows XP Professional. Device Name: Standard Enhanced PCI to USB Host Controller. Why do i see many drivers? Below is a list of drivers that may be suitable for your device. With the different devices, they can have the same driver, it's. The Enhanced Host Controller Interface (EHCI) specification describes the register-level interface for a host controller for the Universal Serial Bus (USB) Revision 2.0. The specification includes a description of the hardware and software interface between system software and the host controller hardware. Being persistent I read that a roll-back to 'Standard' Microsoft drivers might work. I reinstalled VM Workstation 7 and was able to reproduce the same problem. Then I went into Device Manager again and selected 'Roll Back driver' I replaced it with 'Standard Enhanced PCI to USB Host Controller' and everything was back to normal. > to back up a large file. Upon investigating I discovered my Standard > Enhanced > PCI to USB Host Controller was missing from my Device Manager. > > I have run Microsoft Update several times, I have uninstalled all the USB > devices and rebooted to reinstall the USB devices but the missing Host > Controller does not return.

Windows 7
Hi,
Need some expert help - I had to replavc my HD, and did not have reinstall discs- For a novice i have managed to get the laptop up and running again. Two problems, the sound and USB slots done work unless I reboot the laptop. Presarion CQ58 100 SA/ Then it works fine.
I did a free driver mising test and these two drivers are missing AMD Radeon HD Graphics driver and standrad enhanced PCI to USB host controller.
The help i need is gettingh these drivers and secondly is that likely to be the cure to my sick laptop!
Many thanks in advance

Hi:
Download and install the amd chipset drivers and reboot.
Then install the graphics driver:
After you install the above drivers, we'll find out if that fixes all problems.
