How can I tell if I have USB 2.0?

I've checked like you describe it and have enhanced so USB2.0.
But when I apply an WiFi antenna (capable of 300Mbps) on the USB port and do a file transfer the rate is 12Mbps equal to the max of USB1.1.
USB2.0 is capable of 480Mbps! So I don't understand. Please advice. Thanks in Advance

The question is NOT if I have 2.0. It tells me that ad nauseum. GREAT! I have 2.0. The real question. The hard question is which ports are 2.0?!?!?!! How do you find them? Just plugging something into each port doesn't do it. And that alone is a lot of work. The computer is under a desk with lots of cables so it doesn't move easily. When you plug something in that might benefit from 2.0 and wait for the message "This could run faster yada yada yada...." If it doesn't show is that proof? I am not sure.

So what is the fastest easiest way to tell which ports are USB 2.0?

On most computers, and certainly most all newer computers, all ports are the same - if it shows "enhanced" then on most computers all ports are 2.0.

How do I test whether my USB thumbdrive is USB 2.0?

So what if in my device manager it has enhanced usb controller listed twice?? does in mean that all ports (4) are 2.0 or just two, because i used one with a usb device with no problem and then after awhile i had pop ups say the device could perform faster if i pluged it in to the high speed port but i am pretty sure that all ports would be 2.0 my laptop is a toshiba satellite p300-161

I have followed your instructions to find out if I have USB 2 on my 18month old computer running Vista. One of the entries is VIA USB Enhanced Controller. Does this mean I have USB2?

The answer is in the article you just commented on.

Since yesterday I'm getting messages after plugging in my external HD all the time saying my HD can perform faster if plugging it to a faster usb2. But my ports are USB2 and they always worked fine.. Now for some reason it does seem to work slower, 1 hour ago my computer didn't even recognize my HD no more.. Now it does again, but still that message.. My boyfriend said he's getting the same message when plugging my HD into his laptop since yesterday.. What's going on??

Hih there I need to know if audio interfaces like the audiobox usb or fast track pro that are usb powered can go well with my laptop that is a acer extensa 5620z running vista...please it's important let me know if these kind of sound card can run with no problem on my laptop

Hello, i also have an old usb port on my pc, thanks now i know that i don't have usb 2.0, just wondering if an old usb 1.1 port can affect the speed of my internet acces??I use the connection for my phone modem and planning to buy a usb 2.0 adapter if it can speed up my net access, thanks

Depends on your internet connection. USB 1.1 is 12 megabits per second. If your internet connection is faster than that, you'll want USB 2.0 (480 Mbits/sec).

I installed a 2.0 USB card in Pci. I plugged in 3 HiSpeed items , nothing happen, camera card, camera and mouse. Device Manager shows Enhanced... "" What will show up on my screen when I plug something in the 2.0 USB , does it show same as the 1.1 USB?

What if it reads " Standard "universal" PCI to USB host controller as opposed to Standard "enhanced"
