Do I have USB 2.0 on my Windows XP computer?

February 8th, 2007 No comments

How you can tell if you have USB 2.0 on your computer, and why it matters:

If you plug a USB 2.0 device into a USB 1.1 port, Windows XP will display a warning message indicating that it will drop back to the slower data transfer speed. (USB 2.0 clocks in with a data transfer speed of 480 Mbits/second compared to USB 1.1′s 12 Mbits/second.)

1. Right click on “My Computer” and select “Properties.”
2. Select the Hardware tab and click the Device Manager button.
3. When Device Manager appears, click the + sign next to the Universal Serial Bus Controllers branch.

If you see an entry containing the words “Enhanced USB Controller”, then the system has a USB 2.0 controller. If you see an entry containing the words “USB Controller”, the system has a USB 1.1 controller.

Note: This tip applies to both Windows XP Home and Professional editions.

Driverquery command on Windows XP

October 22nd, 2006 No comments

When you are trying to troubleshoot a suspected device driver problem, it can be confusing (and time consuming) to locate detailed information about your device properties. (You can go to “Device Manager”, then select your device from the list and locate the properties for that specific device. If you are just looking for information on one driver, this is not a big deal, but if you need to find detailed information on several devices, this would be take too long.)

There is a tool called Driver Query. (Driverquery.exe) Driver Query will provide you with a detailed list of all the device drivers installed on a local system. (Or on any system on a network) Here’s how to use it:

  1. Open a Command Prompt window.
  2. Type Driverquery on the command line.

You will see the results displayed in a table format in the Command Prompt window. If you want to perform more detailed analysis, you can direct the Driver Query to save the results in a CSV file so you can open them in a spreadsheet application. To do so, type the following on the command line:

Driverquery /v  /fo  csv  > drivers.csv

Note: This tip applies only to Windows XP Professional.
