|"I see 4 hubs, none of which are 'Enhanced' and 4 controllers, one of which IS Enhanced. Does that mean I have USB 2.0 capability on all of the 4 ports? "|
Yes you have USB 2.0 capability, and the drivers have been loaded for it (if they weren't you would not see the Enhanced one) - and going by the age of the mboard probably on all the ports, but you probably have 6 USB ports, not 4 - the number of physical USB ports on the back of the computer and probably plus the two lower down on the front of the case. If you don't have 4 ports on the back you have two, and two more available if you connect a 2 port USB wiring adapter to a header on the mboard (it may already be there in a slot space at the back). If you don't have two on the front of the case, you have 2 or 4 on the back, and four or two more available if you connect two/a 2 port USB wiring adapter(s) to (a) header(s) on the mboard (they/it may already be there in a slot space at the back).
If you double click on each hub, click on Power, it shows you the number of available USB ports for each hub. If there is a device connected it shows you the number of ma it draws, and the number of available ports left.
All USB 2.0 controllers include support for USB 1.1.
The USB 1.1 controller support is listed separately, usually one per two USB ports. Windows finds that support automatically and loads built in drivers.
The Enhanced controller is the USB 2.0 controller. XP must have SP1 or later updates loaded, the mboard chipset drivers must have been loaded, in order for Windows install to install drivers for that.
All the ports, in the case of this mboard, probably support both USB 1.1 and USB 2.0.
They are not labelled differently but you have two types of hubs.
The USB 1.1 hubs usually have two ports (or one).
The USB 2.0 hub has more - 6 in this case - if the only USB you have is built into the mboard, that's usually the same as the number of USB 1.1 hubs x 2.
On my computer the USB 2.0 hub is the last one listed of 5 (I have 8 USB ports available) .
If a device preferably requries USB 2.0, the number of ma it draws is shown only in Power for the USB 2.0 hub, the one with more than two ports.
