neil Posted February 24, 2005 Share Posted February 24, 2005 simplest way is to stick a USB2 device (a flash key for example) into each available usb port.If the port isn't USB2 then a windows pop-up tells you that the device would run faster if a USB2 port is used.If you don't get a message then you've got USB2.similarly, if you plug in a USB1 device to a USB2 port, a message claims that the device isn't compatible with USB2 and will run at the reduced USB speed.

Zxian Posted February 24, 2005 Share Posted February 24, 2005 similarly, if you plug in a USB1 device to a USB2 port, a message claims that the device isn't compatible with USB2 and will run at the reduced USB speed.<{POST_SNAPBACK}>This isn't quite true. Windows will tell you if the USB port isn't fast enough for the device. If the device isn't fast enough, you won't get any kind of message. The device will simply work at 1.0/1.1 speed.
