When I installed a USB 2.0 external hard drive on my Dell P340 Precision WorkStation computer, I got the error that "There are no HI-SPEED USB host controllers installed on this computer." Device Manager does not show an enhanced controller. The only app note I can find at Dell (thanks to a post on EE) says that the problem is solved by downloing the enhanced driver from the driver CD that came with the computer (http://tinyurl.com/5gdnb
). I don't have that disk. Plus, I cannot find the driver on the Dell web site. Plus, at this moment, the Dell Forums appear to be down.
I cannot find the specifications on the system on the Dell site to be sure that this 2.0 GHz P4 with Intel 850 chipset has USB 2.0 ports, but I assume it does. I have older computers that do have 2.0 ports. The operating system is Windows XP SP2. The USB ports are enabled in the BIOS. Remember that the external hard drive is recognized when I boot into XP; it just does not operate at high speed.
The points for this question will be awarded to the person who either determines that the ports on this computer are not high speed, or 2) who provides me with a link to the enhanced USB driver for this motherboard that enables the high speed ports. Here's the link to the drivers page for this computer: http://support.dell.com/support/downloads/devices.aspx?c=us&l=en&s=gen&SystemID=WRK_PNT_P4_340&os=WW1&osl=EN
On a side note, I was just getting ready to order a new Dell system for an elderly couple, but after spending two hours trying to navigate Dell's site for support, I may rethink it. Their site used to be great.
