  • I'm sure one of the parts of my answer will help: 1. For Windows 9x - Check your device manager (right-click my computer and click properties). Click the "+" sign at the side of Universal Serial Bus Controllers, and the Controllers displayed should say 1.0 or 2.0. For Windows XP - Right-click My Computer, click properties, open the Hardware Tab and click the Device Manager button, click the "+" sign to display the Universal Serial Bus Controllers. 2. Check your Bios. The device list should state if your USB is whether 1.0 or 2.0 3. Check your PC Brand and Model (i.e. Compaq Presario 2200) type the name on Google, go to any technical specifications page and check the type of USB port coming with that model. 4. What year is the PC? USB 2.0 was launched on mid-2002. 5. Plug a USB 2.0 device on your PC. Any warning or pop up saying that you are using a 2.0 device on a 1.0 port (sacrificing speed)? 6. If the device you are using have a testing software that checks the device speed, check if its running at more than 12 mbits per second (USB 1.0 runs up to 12 mbits, while 2.0 runs up to 440 mbits per sec). For general knowledge USB ports, whatever version, are compatible and the difference is hardware not software, so the only way to upgrade from 1.0 to 2.0 is changing the USB ports physically. Anyway, if you plug a 1.0 device on a 2.0 port, it will run but on 1.0 speed. Viceversa, this means a 2.0 device on a 1.0 port, will run a 1.0 speed. Just in case, most USB 1.0 ports came out to the market with software problems. To solve this problems look on Google for "USB 1.0 Filter" it will upgrade your port to USB 1.1 (driver only).
  • Plug a USB device in and if they are USB 1, a baloon will pop up and say the device could run faster with a USB 2 port.
