| | How can I tell which USB slots are 2.0 & which are 1.0 My PC has at least 1 USB 2.0 port. The others are USB 1.x. How can I tell which is which?

So how can I tell if it's plugged into the USB 2.0 port, or what port it IS plugged into? Thanks.

| | Re: How can I tell which USB slots are 2.0 & which are 1.0 There might be an easier way. You can switch the Device Manager View so it shows "View by Connection". You can expand the ACPI tree to navigate down to the PCI bus, then the "Enhanced" controller or controllers expanding that will show it's root hub and any USB 2 devices connected. Microsoft also has a USB Device Viewer that shows the fan-out of the controllers, hubs and connected devices. You can get a copy here: http://www.microsoft.com/whdc/device...CViewdwn.mspx?

| | Re: How can I tell which USB slots are 2.0 & which are 1.0 Well I am really confused. I've noticed this usb and enhanced usb nomenclature before in device manager. But I've assumed that all modern computers have ALL usb2 ports. I just downloaded and ran the USB device viewer. According to it I have 20 usb ports. I do not. And by pure chance my keyboard, mouse and UPS are connected to a USB Universal Host Controller and my external hard drive is connected to a USB2 Enhanced Host Controller. And it tells me I have 8 USB2 ports. It's late and dark in this room so I can't crawl around to the back and count the USB ports there and on the front but 8 sounds about right for the total physical USB ports on my machine. "R.

| | Re: How can I tell which USB slots are 2.0 & which are 1.0 Thanks Uwe for the link. I still don't see this clearly though. If my MB has 8 physical USB ports how many USB2 devices can I connect and run at USB2 speeds. And I think I mean enhanced speeds. If I connected an external hard drive to each of the 8 ports would some run at higher speeds than others. Does Windows somehow look at the device and make a judgment call on whether the device should run at USB2 enhanced speeds? Do I read you correctly that it doesn't matter exactly "which" port a device is connected to?
