How do I determine the speed of my USB devices?

[Taz]

I've got several different bits of kit attached to my PC via USB. The USB ports on my PC are USB 2.0 Hi Speed compliant. However, my attached devices are a mixture of 1.1 and 2.0. Is there any way I can check what speed a particular USB device is connected?

I just really need to make sure that my USB 2.0 Hi Speed devices are connected at the highest speed.

You could always try googling the items for their specifications and finding out that way. It would be a lot quicker (unless you have lots of devices) than installing software or finding out via Windows. It won't take that long.

Assuming youre not using any 1.1 hubs, anything that is plugged into a 2 port will be running at 2 speeds.

Unless the device doesmt support 2 speeds, or you have usb2 speeds disabled (there IS a bios option for it!).

If you have a windows 98 CD look in Tools\ResKit\diagnose\

Theres a program called usbview.exe, might be opn the disks of later versions too....

I think its also part of one of the sdk's.. might be where I got it...

Found 'usbview.exe' after a Google search. Shows my printer is connected at 'Low' speed even though it is USB 2.0 compliant. Could it be the cable? Do I need a cable that is designed and certified for USB 2.0 Hi Speed use in order to get the 480Mbs? I just used my old cable that i'm not sure is certified for UBS 2.0 Hi Speed use.

Yes the cable does have to be USB 2.0 compliant. It says on the box/packaging whether it is or not. If it's not compliant, get a nice one from WHSmiths that lights up at both ends for about £12! I did...
