Sparks99,
If you are receiving PC messages that state you should connect your USB 2.0
device to a higher speed USB port, and you know that you have USB 2.0 ports
on your computer, there are certain USB controller upgrades that have been
made available through Microsoft Windows Update that can enable USB 2.0 on
your computer. To get these updates use the following steps:
1. Connect to the Internet if the computer is not already connected.
2. Open Device Manager: (right click Computer, select Properties , and then
Device Manager).
3. Click the plus sign (+) next to Universal Serial Bus Controllers.
4. Right click the first USB Host Controller, select Update Driver Software.
5. Follow the information given to download and install any available
updates.
(The Other Universal Serial BUS Controllers should be automatically updated.)
6. Test the USB device again. (If the message still appears, continue
using these steps with the other USB Controllers until the message no longer
appears.)
7. You should also follow these steps with the USB Root Hubs, if they do
not update automatically. Follow on-screen prompts.
If I were doing this, I would first update Vista with all updates available
on the Microsoft update site. I would do this on the theory that the process
might include USB 2 updates. After installing all Vista updates, test the
USB drvice, and if you still get the message, then follow the above steps.
Note, that in order to have USB 2 cabability, you must have a motherboard
chipset that supports USB 2 and also the BIOS must be properly set to enable
USB 2. Also, on some systems, some USB ports may only support USB 1 or 1.1.
If you get the message after doing all the updates, try a different port.
Moreover, you can check in Device Manager, under Universal Serial Bus
Controllers, to see whether you already have USB 2.0 drivers installed. Do
this before trying to update the drivers. If one or more USB Host
Controllers are shown as:
Standard Enhanced PCI to USB Host Controller (it's USB 2.0)
If any are listed as:
Standard Universal PCI to to USB Host Controller (its USB 1.0/1.1)
Note that USB 2.0 has the word Enhanced while the other has the word
Universal.
Another way to check which USB drivers you have installed is the check the
name of the drivers that are installed under USB Controller Properties Driver
tab, as follows:
usbuhci.sys (it's USB 2.0)
usbehci.sys (it's USB 1.0/1.1)
Do these checks before updating. If your system checks out as haveing all
the USB 2.0 drivers installed, then you don't need to update.
Post back if you have questions.
