How to tell which USB sockets are USB 2

On my PC I have 4 USB sockets at the back and I also have two more USB sockets on the front of my PC, I was wondering how do I tell if they are all USB 2, as something makes me think that the USB's on the front of my PC would be USB 1 as this was the case if I am not mistaken on my last PC, how can I check to see if they are all USB 2 or USB 1.

Come to think of it, unless some of them are via a PCI card, they should all be the same. If they are connected to the motherboard, they will be all the same.

Is there any way that I can check without opening the PC case.

If you have a USB 2.0 capable device and you plug it into a USB socket if its USB 1.1 it should come up with a message saying something about its able to work quicker if you use USB 2.0. My little MP3 player for example is USB 2.0 and comes up with this, even if it didn't if you use it and drop some files on it its plain to see when its slower and therefore using USB 1.1.

It should say enhanced usb in device manager if you have usb2 sockets.

Acolyte is referring to USB Controllers in Device Manager.

I have just ran a couple of tests.

I have a got a Western Digital Passport USB 2 external hard drive, I also have an AC powered 7 port USB hub. I have just done a test where I dragged and dropped a file, I timed how long it took for it to finish saving it to the external hard drive (this was done with the external hard drive plugged into the 7 port USB hub) I then done the same test with the same file, but this time I connected the external hard drive into the USB's I have at the front of my PC, I timed both tests and the time took on both tests was exactly the same.

Also I did not see any message appear when I either connected the external hard drive into to the front or back USB's showing "its able to work quicker if you use USB 2.0". So therefore can I assume that all the USB sockets on my PC are USB 2 ?

There must be a good chance. to check for sure follow the advice of Acolyte/Stuartli.

Start>right click My computer>properties>hardware>device manager and then expand the Universal Serial Bus Controllers. If you see "enhanced" it means you have USB2.

I've just run the same on my new laptop with 3 USB2 ports. It reports:

SIS 7001 PCI to USB Open Host Controller
SIS 7001 PCI to USB Open Host Controller
SIS PCI to USB Enhanced Host Controller

Plus a variety of Generic USB Hubs and USB Root Hubs.

Why only one Enhanced reported?
