USB Hubs and Devices

I have an Abit IP35 Pro motherboard which has 2 ports that are USB2. When I plug my gaming mouse and my SteelSeries 5HV2 USB sound card which are both USB2 and check under USB Root Hub devices, it shows that they are running in Full Speed and not on the High Speed USB Root Hubs. I thought all 4 USB ports on the back of my computer were USB2 and thus the USB2 devices plugged in those ports will run at High Speed or USB2 speed, but it seems like that's not the case. Can someone help me figure out what's going on and why it's like this. I can post screenshots just tell me what I should snap.

Thanks!

I thought USB 2.0 meant High-Speed while USB 1.0 can work in full-speed and low speed. Correct me if I'm wrong.

And in the device manager, two of the root hubs show up as enhanced and are working in high-speed but there are no devices associated with them. I thought the gaming mouse and USB sound card would be high speed devices since they are USB 2.0 and especially the sound card since it requires quite a bit of bandwidth to work.

Actually, USB 1.0 is just the old 4 prong type of USB connector. As Hopalong says, high-speed USB 2.0 ports are very rare. I'm not to sure what your root hubs showing up as advanced is.

Do you mean high-speed "devices" or ports? Because look, here is a screen shot of what I'm talking about:



Even in the BIOS there is an option of whether the USB speed should be "low or full" or "high speed" and I've selected High Speed so the hub/port should be running at high-speed. Now the question is, why aren't my devices running at high speed?

OK I can see what your saying, could you go from where you are in your pic and click on Power Management just to make sure the "allow the computer to turn this off" is unchecked.

Yes, I have unchecked all those check boxes for all the USB Root Hubs. The thing is, the devices are not turning off, they are working fine, it's just that I was wondering why they are not running in high-speed mode when it is available to them. The devices would work much faster than they are now that way. I thought there might be a windows setting or something preventing it from working or maybe windows is choosing how the devices are going to work.

Anyway, if someone knows how it all works, let me know... I'm interested to hear it.

Thanks a lot so far!

The way I understand it the "Standard Enhanced PCI to USB Host Controller" entry is for the USB controller, the chip that drives the ports. You will never see anything connected to it as it connects to the "Root Hub(s)". Seeing that device under Universal Serial Bus controllers means you have USB 2 support. If you plug a USB 2 capable device into a USB 1 port you will get a "This device could preform faster...." pop up message. If you didn't get that message I wouldn't worry about it. I'm sure someone will correct me if I'm wrong.

So you are saying the devices are already running at their optimum speeds?

USB 1 and USB 2 devices use the same 4 pin connector, you can't tell one from the other just by looking at them. A USB 1 spec-ed device will plug into and work in a USB 2 port. It just won't work at the full USB 2 speed. Same deal for a USB 2 device pluged into a USB 1 port. USB 2.0 is quit common these days unless you have a really old PC.
