USB 1.1 and 2.0 controllers in same PC?

[Nathan McNulty]

This is the way my computer looks as well. I have 8 USB 2.0 ports and
they all run at that speed. These are just the controllers, not the
actual ports

Also, the hex is most likely a location marker or something like that,
but I'm not sure.

I have a 3-month-old HP Pavilion a450n desktop computer running Windows
XP SP1. I am curious about the USB controllers reported in Device
Manager. I see 5 controllers, which appear like this:

Intel(R) 82801EB USB Universal Host Controller - 24D2
Intel(R) 82801EB USB Universal Host Controller - 24D4
Intel(R) 82801EB USB Universal Host Controller - 24D7
Intel(R) 82801EB USB Universal Host Controller - 24DE
Intel(R) 82801EB USB2 Enhanced Host Controller - 24DD

Can this be right? Do I really have 4 USB 1.1 controllers and only one
USB 2.0 controller?

If, as I suspect, this doesn't make sense, is my computer somehow
misconfigured?

(Also, what do the hex numbers shown in the above list refer to?)

Thanks,
- Bob

You could try putting a usb 1.1 device in each of the usb ports. If any of
the usb ports are NOT 2.0, you will not get the error message that a usb 1.1
device has been plugged into a high speed port. I.e., as long as you get
the error message for each of the ports, you know that they are all 2.0.

That said, it's unlikely that the pc comes with both 1.1 and 2.0 ports. If
from the above you do not get the error message for 1 or more ports, you can
open a command prompt window, type
set devmgr_show_nonpresent_devices=1
then, press enter
then type
compmgmt.msc
press enter
click on device manager and view, show hidden devices
under USB Controllers, delete all controllers and hubs, restart.
